ElasticLoadBalancingv2.Client¶A low-level client representing Elastic Load Balancing (Elastic Load Balancing v2)
A load balancer distributes incoming traffic across targets, such as your EC2 instances. This enables you to increase the availability of your application. The load balancer also monitors the health of its registered targets and ensures that it routes traffic only to healthy targets. You configure your load balancer to accept incoming traffic by specifying one or more listeners, which are configured with a protocol and port number for connections from clients to the load balancer. You configure a target group with a protocol and port number for connections from the load balancer to the targets, and with health check settings to be used when checking the health status of the targets.
Elastic Load Balancing supports the following types of load balancers: Application Load Balancers, Network Load Balancers, Gateway Load Balancers, and Classic Load Balancers. This reference covers the following load balancer types:
For more information, see the Elastic Load Balancing User Guide .
All Elastic Load Balancing operations are idempotent, which means that they complete at most one time. If you repeat an operation, it succeeds.

can_paginate(operation_name)¶Check if an operation can be paginated.
create_foo, and you'd normally invoke the
operation as client.create_foo(**kwargs), if the
create_foo operation can be paginated, you can use the
call client.get_paginator("create_foo").True if the operation can be paginated,
False otherwise.close()¶Closes underlying endpoint connections.
create_listener(**kwargs)¶Creates a listener for the specified Application Load Balancer, Network Load Balancer, or Gateway Load Balancer.
For more information, see the following:
This operation is idempotent, which means that it completes at most one time. If you attempt to create multiple listeners with the same settings, each call succeeds.

[REQUIRED]
The Amazon Resource Name (ARN) of the listener.
[REQUIRED]
The conditions.
Information about a condition for a rule.
Each rule can optionally include up to one of each of the following conditions: http-request-method , host-header , path-pattern , and source-ip . Each rule can also optionally include one or more of each of the following conditions: http-header and query-string . Note that the value for a condition cannot be empty.
The field in the HTTP request. The following are the possible values:
http-headerhttp-request-methodhost-headerpath-patternquery-stringsource-ipThe condition value. Specify only when Field is host-header or path-pattern . Alternatively, to specify multiple host names or multiple path patterns, use HostHeaderConfig or PathPatternConfig .
If Field is host-header and you are not using HostHeaderConfig , you can specify a single host name (for example, my.example.com) in Values . A host name is case insensitive, can be up to 128 characters in length, and can contain any of the following characters.
If Field is path-pattern and you are not using PathPatternConfig , you can specify a single path pattern (for example, /img/*) in Values . A path pattern is case-sensitive, can be up to 128 characters in length, and can contain any of the following characters.
Information for a host header condition. Specify only when Field is host-header .
One or more host names. The maximum size of each name is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of the strings matches the host name.
Information for a path pattern condition. Specify only when Field is path-pattern .
One or more path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig .
Information for an HTTP header condition. Specify only when Field is http-header .
The name of the HTTP header field. The maximum size is 40 characters. The header name is case insensitive. The allowed characters are specified by RFC 7230. Wildcards are not supported.
You can't use an HTTP header condition to specify the host header. Use HostHeaderConditionConfig to specify a host header condition.
One or more strings to compare against the value of the HTTP header. The maximum size of each string is 128 characters. The comparison strings are case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If the same header appears multiple times in the request, we search them in order until a match is found.
If you specify multiple strings, the condition is satisfied if one of the strings matches the value of the HTTP header. To require that all of the strings are a match, create one condition per string.
Information for a query string condition. Specify only when Field is query-string .
One or more key/value pairs or values to find in the query string. The maximum size of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in Values using a '' character.
If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.
Information about a key/value pair.
The key. You can omit the key.
The value.
Information for an HTTP method condition. Specify only when Field is http-request-method .
The name of the request method. The maximum size is 40 characters. The allowed characters are A-Z, hyphen (-), and underscore (_). The comparison is case sensitive. Wildcards are not supported; therefore, the method name must be an exact match.
If you specify multiple strings, the condition is satisfied if one of the strings matches the HTTP request method. We recommend that you route GET and HEAD requests in the same way, because the response to a HEAD request may be cached.
Information for a source IP condition. Specify only when Field is source-ip .
One or more source IP addresses, in CIDR format. You can use both IPv4 and IPv6 addresses. Wildcards are not supported.
If you specify multiple addresses, the condition is satisfied if the source IP address of the request matches one of the CIDR blocks. This condition is not satisfied by the addresses in the X-Forwarded-For header. To search for addresses in the X-Forwarded-For header, use HttpHeaderConditionConfig .
[REQUIRED]
The rule priority. A listener can't have multiple rules with the same priority.
[REQUIRED]
The actions.
Information about an action.
Each rule must include exactly one of the following types of actions: forward , fixed-response , or redirect , and it must be the last action to be performed.
The type of action.
The Amazon Resource Name (ARN) of the target group. Specify only when Type is forward and you want to route to a single target group. To route to one or more target groups, use ForwardConfig instead.
[HTTPS listeners] Information about an identity provider that is compliant with OpenID Connect (OIDC). Specify only when Type is authenticate-oidc .
The OIDC issuer identifier of the IdP. This must be a full URL, including the HTTPS protocol, the domain, and the path.
The authorization endpoint of the IdP. This must be a full URL, including the HTTPS protocol, the domain, and the path.
The token endpoint of the IdP. This must be a full URL, including the HTTPS protocol, the domain, and the path.
The user info endpoint of the IdP. This must be a full URL, including the HTTPS protocol, the domain, and the path.
The OAuth 2.0 client identifier.
The OAuth 2.0 client secret. This parameter is required if you are creating a rule. If you are modifying a rule, you can omit this parameter if you set UseExistingClientSecret to true.
The name of the cookie used to maintain session information. The default is AWSELBAuthSessionCookie.
The set of user claims to be requested from the IdP. The default is openid .
To verify which scope values your IdP supports and how to separate multiple values, see the documentation for your IdP.
The maximum duration of the authentication session, in seconds. The default is 604800 seconds (7 days).
The query parameters (up to 10) to include in the redirect request to the authorization endpoint.
The behavior if the user is not authenticated. The following are possible values:
Indicates whether to use the existing client secret when modifying a rule. If you are creating a rule, you can omit this parameter or set it to false.
[HTTPS listeners] Information for using Amazon Cognito to authenticate users. Specify only when Type is authenticate-cognito .
The Amazon Resource Name (ARN) of the Amazon Cognito user pool.
The ID of the Amazon Cognito user pool client.

Each rule can optionally include up to one of each of the following conditions: http-request-method , host-header , path-pattern , and source-ip . Each rule can also optionally include one or more of each of the following conditions: http-header and query-string . Note that the value for a condition cannot be empty.
Field (string) --
The field in the HTTP request. The following are the possible values:
http-headerhttp-request-methodhost-headerpath-patternquery-stringsource-ipValues (list) --
The condition value. Specify only when Field is host-header or path-pattern . Alternatively, to specify multiple host names or multiple path patterns, use HostHeaderConfig or PathPatternConfig .
If Field is host-header and you are not using HostHeaderConfig , you can specify a single host name (for example, my.example.com) in Values . A host name is case insensitive, can be up to 128 characters in length, and can contain any of the following characters.
If Field is path-pattern and you are not using PathPatternConfig , you can specify a single path pattern (for example, /img/*) in Values . A path pattern is case-sensitive, can be up to 128 characters in length, and can contain any of the following characters.
HostHeaderConfig (dict) --
Information for a host header condition. Specify only when Field is host-header .
Values (list) --
One or more host names. The maximum size of each name is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of the strings matches the host name.
PathPatternConfig (dict) --
Information for a path pattern condition. Specify only when Field is path-pattern .
Values (list) --
One or more path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig .
HttpHeaderConfig (dict) --
Information for an HTTP header condition. Specify only when Field is http-header .
HttpHeaderName (string) --
The name of the HTTP header field. The maximum size is 40 characters. The header name is case insensitive. The allowed characters are specified by RFC 7230. Wildcards are not supported.
You can't use an HTTP header condition to specify the host header. Use HostHeaderConditionConfig to specify a host header condition.

One or more strings to compare against the value of the HTTP header. The maximum size of each string is 128 characters. The comparison strings are case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If the same header appears multiple times in the request, we search them in order until a match is found.
If you specify multiple strings, the condition is satisfied if one of the strings matches the value of the HTTP header. To require that all of the strings are a match, create one condition per string.
QueryStringConfig (dict) --
Information for a query string condition. Specify only when Field is query-string .
Values (list) --
One or more key/value pairs or values to find in the query string. The maximum size of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in Values using a '' character.
If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.
(dict) --
Information about a key/value pair.
Key (string) --
The key. You can omit the key.
Value (string) --
The value.

Values (list) --
The name of the request method. The maximum size is 40 characters. The allowed characters are A-Z, hyphen (-), and underscore (_). The comparison is case sensitive. Wildcards are not supported; therefore, the method name must be an exact match.
If you specify multiple strings, the condition is satisfied if one of the strings matches the HTTP request method. We recommend that you route GET and HEAD requests in the same way, because the response to a HEAD request may be cached.
SourceIpConfig (dict) --
Information for a source IP condition. Specify only when Field is source-ip .
Values (list) --
One or more source IP addresses, in CIDR format. You can use both IPv4 and IPv6 addresses. Wildcards are not supported.

Information about the target group attributes
Information about a target group attribute.
The name of the attribute.
The following attribute is supported by all load balancers:
deregistration_delay.timeout_seconds - The amount of time, in seconds, for Elastic Load Balancing to wait before changing the state of a deregistering target from draining to unused . The range is 0-3600 seconds. The default value is 300 seconds. If the target is a Lambda function, this attribute is not supported.The following attributes are supported by both Application Load Balancers and Network Load Balancers:
stickiness.enabled - Indicates whether sticky sessions are enabled. The value is true or false . The default is false .stickiness.type - The type of sticky sessions. The possible values are lb_cookie and app_cookie for Application Load Balancers or source_ip for Network Load Balancers.The following attributes are supported only if the load balancer is an Application Load Balancer and the target is an instance or an IP address:
load_balancing.algorithm.type - The load balancing algorithm determines how the load balancer selects targets when routing requests. The value is round_robin or least_outstanding_requests . The default is round_robin .slow_start.duration_seconds - The time period, in seconds, during which a newly registered target receives an increasing share of the traffic to the target group. After this time period ends, the target receives its full share of traffic. The range is 30-900 seconds (15 minutes). The default is 0 seconds (disabled).stickiness.app_cookie.cookie_name - Indicates the name of the application-based cookie. Names that start with the following prefixes are not allowed: AWSALB , AWSALBAPP , and AWSALBTG ; they're reserved for use by the load balancer.stickiness.app_cookie.duration_seconds - The time period, in seconds, during which requests from a client should be routed to the same target. After this time period expires, the application-based cookie is considered stale. The range is 1 second to 1 week (604800 seconds). The default value is 1 day (86400 seconds).stickiness.lb_cookie.duration_seconds - The time period, in seconds, during which requests from a client should be routed to the same target. After this time period expires, the load balancer-generated cookie is considered stale. The range is 1 second to 1 week (604800 seconds). The default value is 1 day (86400 seconds).The following attribute is supported only if the load balancer is an Application Load Balancer and the target is a Lambda function:
lambda.multi_value_headers.enabled - Indicates whether the request and response headers that are exchanged between the load balancer and the Lambda function include arrays of values or strings. The value is true or false . The default is false . If the value is false and the request contains a duplicate header field name or query parameter key, the load balancer uses the last value sent by the client.The following attributes are supported only by Network Load Balancers:
deregistration_delay.connection_termination.enabled - Indicates whether the load balancer terminates connections at the end of the deregistration timeout. The value is true or false . The default is false .preserve_client_ip.enabled - Indicates whether client IP preservation is enabled. The value is true or false . The default is disabled if the target group type is IP address and the target group protocol is TCP or TLS. Otherwise, the default is enabled. Client IP preservation cannot be disabled for UDP and TCP_UDP target groups.proxy_protocol_v2.enabled - Indicates whether Proxy Protocol version 2 is enabled. The value is true or false .

get_paginator(operation_name)¶Create a paginator for an operation.
create_foo, and you'd normally invoke the
operation as client.create_foo(**kwargs), if the
create_foo operation can be paginated, you can use the
call client.get_paginator("create_foo").client.can_paginate method to
check if an operation is pageable.get_waiter(waiter_name)¶Returns an object that can wait for some condition.
modify_listener(**kwargs)¶Replaces the specified properties of the specified listener. Any properties that you do not specify remain unchanged.
Changing the protocol from HTTPS to HTTP, or from TLS to TCP, removes the security policy and default certificate properties. If you change the protocol from HTTP to HTTPS, or from TCP to TLS, you must add the security policy and default certificate properties.
To add an item to a list, remove an item from a list, or update an item in a list, you must provide the entire list. For example, to add an action, specify a list with the current actions plus the new action.

[REQUIRED]
The Amazon Resource Name (ARN) of the rule.
The conditions.
Information about a condition for a rule.
Each rule can optionally include up to one of each of the following conditions: http-request-method , host-header , path-pattern , and source-ip . Each rule can also optionally include one or more of each of the following conditions: http-header and query-string . Note that the value for a condition cannot be empty.
The field in the HTTP request. The following are the possible values:
http-headerhttp-request-methodhost-headerpath-patternquery-stringsource-ipThe condition value. Specify only when Field is host-header or path-pattern . Alternatively, to specify multiple host names or multiple path patterns, use HostHeaderConfig or PathPatternConfig .
If Field is host-header and you are not using HostHeaderConfig , you can specify a single host name (for example, my.example.com) in Values . A host name is case insensitive, can be up to 128 characters in length, and can contain any of the following characters.
If Field is path-pattern and you are not using PathPatternConfig , you can specify a single path pattern (for example, /img/*) in Values . A path pattern is case-sensitive, can be up to 128 characters in length, and can contain any of the following characters.
Information for a host header condition. Specify only when Field is host-header .
One or more host names. The maximum size of each name is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of the strings matches the host name.
Information for a path pattern condition. Specify only when Field is path-pattern .
One or more path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig .
Information for an HTTP header condition. Specify only when Field is http-header .
The name of the HTTP header field. The maximum size is 40 characters. The header name is case insensitive. The allowed characters are specified by RFC 7230. Wildcards are not supported.
You can't use an HTTP header condition to specify the host header. Use HostHeaderConditionConfig to specify a host header condition.
One or more strings to compare against the value of the HTTP header. The maximum size of each string is 128 characters. The comparison strings are case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If the same header appears multiple times in the request, we search them in order until a match is found.
If you specify multiple strings, the condition is satisfied if one of the strings matches the value of the HTTP header. To require that all of the strings are a match, create one condition per string.
Information for a query string condition. Specify only when Field is query-string .
One or more key/value pairs or values to find in the query string. The maximum size of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in Values using a '' character.
If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.
Information about a key/value pair.
The key. You can omit the key.
The value.
Information for an HTTP method condition. Specify only when Field is http-request-method .
The name of the request method. The maximum size is 40 characters. The allowed characters are A-Z, hyphen (-), and underscore (_). The comparison is case sensitive. Wildcards are not supported; therefore, the method name must be an exact match.
If you specify multiple strings, the condition is satisfied if one of the strings matches the HTTP request method. We recommend that you route GET and HEAD requests in the same way, because the response to a HEAD request may be cached.
Information for a source IP condition. Specify only when Field is source-ip .
One or more source IP addresses, in CIDR format. You can use both IPv4 and IPv6 addresses. Wildcards are not supported.
If you specify multiple addresses, the condition is satisfied if the source IP address of the request matches one of the CIDR blocks. This condition is not satisfied by the addresses in the X-Forwarded-For header. To search for addresses in the X-Forwarded-For header, use HttpHeaderConditionConfig .
The actions.
Information about an action.
Each rule must include exactly one of the following types of actions: forward , fixed-response , or redirect , and it must be the last action to be performed.
The type of action.
The Amazon Resource Name (ARN) of the target group. Specify only when Type is forward and you want to route to a single target group. To route to one or more target groups, use ForwardConfig instead.

register_targets(**kwargs)¶Registers the specified targets with the specified target group.
If the target is an EC2 instance, it must be in the running state when you register it.
By default, the load balancer routes requests to registered targets using the protocol and port for the target group. Alternatively, you can override the port for a target when you register it. You can register each EC2 instance or IP address with the same target group multiple times using different ports.
With a Network Load Balancer, you cannot register instances by instance ID if they have the following instance types: C1, CC1, CC2, CG1, CG2, CR1, CS1, G1, G2, HI1, HS1, M1, M2, M3, and T1. You can register instances of these types by IP address.

Response Structure
Information about the rules.
Information about a rule.
The Amazon Resource Name (ARN) of the rule.
The priority.
The conditions. Each rule can include zero or one of the following conditions: http-request-method , host-header , path-pattern , and source-ip , and zero or more of the following conditions: http-header and query-string .
Information about a condition for a rule.
Each rule can optionally include up to one of each of the following conditions: http-request-method , host-header , path-pattern , and source-ip . Each rule can also optionally include one or more of each of the following conditions: http-header and query-string . Note that the value for a condition cannot be empty.
The field in the HTTP request. The following are the possible values:
http-headerhttp-request-methodhost-headerpath-patternquery-stringsource-ipThe condition value. Specify only when Field is host-header or path-pattern . Alternatively, to specify multiple host names or multiple path patterns, use HostHeaderConfig or PathPatternConfig .
If Field is host-header and you are not using HostHeaderConfig , you can specify a single host name (for example, my.example.com) in Values . A host name is case insensitive, can be up to 128 characters in length, and can contain any of the following characters.
If Field is path-pattern and you are not using PathPatternConfig , you can specify a single path pattern (for example, /img/*) in Values . A path pattern is case-sensitive, can be up to 128 characters in length, and can contain any of the following characters.
Information for a host header condition. Specify only when Field is host-header .
One or more host names. The maximum size of each name is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of the strings matches the host name.
Information for a path pattern condition. Specify only when Field is path-pattern .
One or more path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig .
Information for an HTTP header condition. Specify only when Field is http-header .
The name of the HTTP header field. The maximum size is 40 characters. The header name is case insensitive. The allowed characters are specified by RFC 7230. Wildcards are not supported.
You can't use an HTTP header condition to specify the host header. Use HostHeaderConditionConfig to specify a host header condition.
One or more strings to compare against the value of the HTTP header. The maximum size of each string is 128 characters. The comparison strings are case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If the same header appears multiple times in the request, we search them in order until a match is found.
If you specify multiple strings, the condition is satisfied if one of the strings matches the value of the HTTP header. To require that all of the strings are a match, create one condition per string.
Information for a query string condition. Specify only when Field is query-string .
One or more key/value pairs or values to find in the query string. The maximum size of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in Values using a '' character.
If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.
Information about a key/value pair.
The key. You can omit the key.
The value.
Information for an HTTP method condition. Specify only when Field is http-request-method .
The name of the request method. The maximum size is 40 characters. The allowed characters are A-Z, hyphen (-), and underscore (_). The comparison is case sensitive. Wildcards are not supported; therefore, the method name must be an exact match.
If you specify multiple strings, the condition is satisfied if one of the strings matches the HTTP request method. We recommend that you route GET and HEAD requests in the same way, because the response to a HEAD request may be cached.
Information for a source IP condition. Specify only when Field is source-ip .
One or more source IP addresses, in CIDR format. You can use both IPv4 and IPv6 addresses. Wildcards are not supported.
If you specify multiple addresses, the condition is satisfied if the source IP address of the request matches one of the CIDR blocks. This condition is not satisfied by the addresses in the X-Forwarded-For header. To search for addresses in the X-Forwarded-For header, use HttpHeaderConditionConfig .
The actions. Each rule must include exactly one of the following types of actions: forward , redirect , or fixed-response , and it must be the last action to be performed.

Each rule can optionally include up to one of each of the following conditions: http-request-method , host-header , path-pattern , and source-ip . Each rule can also optionally include one or more of each of the following conditions: http-header and query-string . Note that the value for a condition cannot be empty.
Field (string) --
The field in the HTTP request. The following are the possible values:
http-headerhttp-request-methodhost-headerpath-patternquery-stringsource-ipValues (list) --
The condition value. Specify only when Field is host-header or path-pattern . Alternatively, to specify multiple host names or multiple path patterns, use HostHeaderConfig or PathPatternConfig .
If Field is host-header and you are not using HostHeaderConfig , you can specify a single host name (for example, my.example.com) in Values . A host name is case insensitive, can be up to 128 characters in length, and can contain any of the following characters.
If Field is path-pattern and you are not using PathPatternConfig , you can specify a single path pattern (for example, /img/*) in Values . A path pattern is case-sensitive, can be up to 128 characters in length, and can contain any of the following characters.
HostHeaderConfig (dict) --
Information for a host header condition. Specify only when Field is host-header .
Values (list) --
One or more host names. The maximum size of each name is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of the strings matches the host name.
PathPatternConfig (dict) --
Information for a path pattern condition. Specify only when Field is path-pattern .
Values (list) --
One or more path patterns to compare against the request URL. The maximum size of each string is 128 characters. The comparison is case sensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If you specify multiple strings, the condition is satisfied if one of them matches the request URL. The path pattern is compared only to the path of the URL, not to its query string. To compare against the query string, use QueryStringConditionConfig .
HttpHeaderConfig (dict) --
Information for an HTTP header condition. Specify only when Field is http-header .
HttpHeaderName (string) --
The name of the HTTP header field. The maximum size is 40 characters. The header name is case insensitive. The allowed characters are specified by RFC 7230. Wildcards are not supported.
You can't use an HTTP header condition to specify the host header. Use HostHeaderConditionConfig to specify a host header condition.

One or more strings to compare against the value of the HTTP header. The maximum size of each string is 128 characters. The comparison strings are case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character).
If the same header appears multiple times in the request, we search them in order until a match is found.
If you specify multiple strings, the condition is satisfied if one of the strings matches the value of the HTTP header. To require that all of the strings are a match, create one condition per string.
QueryStringConfig (dict) --
Information for a query string condition. Specify only when Field is query-string .
Values (list) --
One or more key/value pairs or values to find in the query string. The maximum size of each string is 128 characters. The comparison is case insensitive. The following wildcard characters are supported: * (matches 0 or more characters) and ? (matches exactly 1 character). To search for a literal '*' or '?' character in a query string, you must escape these characters in Values using a '' character.
If you specify multiple key/value pairs or values, the condition is satisfied if one of them is found in the query string.
(dict) --
Information about a key/value pair.
Key (string) --
The key. You can omit the key.
Value (string) --
The value.
HttpRequestMethodConfig (dict) --
Information for an HTTP method condition. Specify only when Field is http-request-method .
Values (list) --
The name of the request method. The maximum size is 40 characters. The allowed characters are A-Z, hyphen (-), and underscore (_). The comparison is case sensitive. Wildcards are not supported; therefore, the method name must be an exact match.
If you specify multiple strings, the condition is satisfied if one of the strings matches the HTTP request method. We recommend that you route GET and HEAD requests in the same way, because the response to a HEAD request may be cached.
SourceIpConfig (dict) --
Information for a source IP condition. Specify only when Field is source-ip .
Values (list) --
One or more source IP addresses, in CIDR format. You can use both IPv4 and IPv6 addresses. Wildcards are not supported.
If you specify multiple addresses, the condition is satisfied if the source IP address of the request matches one of the CIDR blocks. This condition is not satisfied by the addresses in the X-Forwarded-For header. To search for addresses in the X-Forwarded-For header, use HttpHeaderConditionConfig .
Actions (list) --

[REQUIRED]
The Amazon Resource Name (ARN) of the target group.
The targets.
Information about a target.
The ID of the target. If the target type of the target group is instance , specify an instance ID. If the target type is ip , specify an IP address. If the target type is lambda , specify the ARN of the Lambda function. If the target type is alb , specify the ARN of the Application Load Balancer target.
The port on which the target is listening. If the target group protocol is GENEVE, the supported port is 6081. If the target type is alb , the targeted Application Load Balancer must have at least one listener whose port matches the target group port. Not used if the target is a Lambda function.
An Availability Zone or all . This determines whether the target receives traffic from the load balancer nodes in the specified Availability Zone or from all enabled Availability Zones for the load balancer.
This parameter is not supported if the target type of the target group is instance or alb .
If the target type is ip and the IP address is in a subnet of the VPC for the target group, the Availability Zone is automatically detected and this parameter is optional. If the IP address is outside the VPC, this parameter is required.
With an Application Load Balancer, if the target type is ip and the IP address is outside the VPC for the target group, the only supported value is all .
If the target type is lambda , this parameter is optional and the only supported value is all .
