DescribeAutoScalingGroups#

class AutoScaling.Paginator.DescribeAutoScalingGroups#

paginator = client.get_paginator('describe_auto_scaling_groups')

paginate(**kwargs)#

Creates an iterator that will paginate through responses from AutoScaling.Client.describe_auto_scaling_groups().

Request Syntax

response_iterator = paginator.paginate(
    AutoScalingGroupNames=[
        'string',
    ],
    Filters=[
        {
            'Name': 'string',
            'Values': [
                'string',
            ]
        },
    ],
    PaginationConfig={
        'MaxItems': 123,
        'PageSize': 123,
        'StartingToken': 'string'
    }
)

Parameters:

AutoScalingGroupNames (list) –
The names of the Auto Scaling groups. By default, you can only specify up to 50 names. You can optionally increase this limit using the MaxRecords property.

If you omit this property, all Auto Scaling groups are described.
- (string) –
Filters (list) –
One or more filters to limit the results based on specific tags.
- (dict) –
  
  Describes a filter that is used to return a more specific list of results from a describe operation.
  
  If you specify multiple filters, the filters are automatically logically joined with an AND, and the request returns only the results that match all of the specified filters.
  
  For more information, see Tag Auto Scaling groups and instances in the Amazon EC2 Auto Scaling User Guide.
  - Name (string) –
    
    The name of the filter.
    
    The valid values for Name depend on which API operation you’re using with the filter ( DescribeAutoScalingGroups or DescribeTags).
    
    DescribeAutoScalingGroups
    
    Valid values for Name include the following:
    - tag-key - Accepts tag keys. The results only include information about the Auto Scaling groups associated with these tag keys.
    - tag-value - Accepts tag values. The results only include information about the Auto Scaling groups associated with these tag values.
    - tag:<key> - Accepts the key/value combination of the tag. Use the tag key in the filter name and the tag value as the filter value. The results only include information about the Auto Scaling groups associated with the specified key/value combination.
    DescribeTags
    
    Valid values for Name include the following:
    - auto-scaling-group - Accepts the names of Auto Scaling groups. The results only include information about the tags associated with these Auto Scaling groups.
    - key - Accepts tag keys. The results only include information about the tags associated with these tag keys.
    - value - Accepts tag values. The results only include information about the tags associated with these tag values.
    - propagate-at-launch - Accepts a Boolean value, which specifies whether tags propagate to instances at launch. The results only include information about the tags associated with the specified Boolean value.
  - Values (list) –
    
    One or more filter values. Filter values are case-sensitive.
    
    If you specify multiple values for a filter, the values are automatically logically joined with an OR, and the request returns all results that match any of the specified values. For example, specify “tag:environment” for the filter name and “production,development” for the filter values to find Auto Scaling groups with the tag “environment=production” or “environment=development”.
    - (string) –
PaginationConfig (dict) –
A dictionary that provides parameters to control pagination.
- MaxItems (integer) –
  
  The total number of items to return. If the total number of items available is more than the value specified in max-items then a NextToken will be provided in the output that you can use to resume pagination.
- PageSize (integer) –
  
  The size of each page.
- StartingToken (string) –
  
  A token to specify where to start paginating. This is the NextToken from a previous response.

Return type:

dict

Returns:

If the value is $Default, Amazon EC2 Auto Scaling selects the default version of the launch template when launching instances. The default value is $Default.
        
        Overrides (list) –
        
        Any properties that you specify override the same properties in the launch template.
        
        (dict) –
        
        Use this structure to let Amazon EC2 Auto Scaling do the following when the Auto Scaling group has a mixed instances policy:
        
        Override the instance type that is specified in the launch template.
        
        Use multiple instance types.
        
        Specify the instance types that you want, or define your instance requirements instead and let Amazon EC2 Auto Scaling provision the available instance types that meet your requirements. This can provide Amazon EC2 Auto Scaling with a larger selection of instance types to choose from when fulfilling Spot and On-Demand capacities. You can view which instance types are matched before you apply the instance requirements to your Auto Scaling group.
        
        After you define your instance requirements, you don’t have to keep updating these settings to get new EC2 instance types automatically. Amazon EC2 Auto Scaling uses the instance requirements of the Auto Scaling group to determine whether a new EC2 instance type can be used.
        
        InstanceType (string) –
        
        The instance type, such as m3.xlarge. You must specify an instance type that is supported in your requested Region and Availability Zones. For more information, see Instance types in the Amazon EC2 User Guide for Linux Instances.
        
        You can specify up to 40 instance types per Auto Scaling group.
        
        WeightedCapacity (string) –
        
        If you provide a list of instance types to use, you can specify the number of capacity units provided by each instance type in terms of virtual CPUs, memory, storage, throughput, or other relative performance characteristic. When a Spot or On-Demand Instance is launched, the capacity units count toward the desired capacity. Amazon EC2 Auto Scaling launches instances until the desired capacity is totally fulfilled, even if this results in an overage. For example, if there are two units remaining to fulfill capacity, and Amazon EC2 Auto Scaling can only launch an instance with a WeightedCapacity of five units, the instance is launched, and the desired capacity is exceeded by three units. For more information, see Configure an Auto Scaling group to use instance weights in the Amazon EC2 Auto Scaling User Guide. Value must be in the range of 1–999.
        
        If you specify a value for WeightedCapacity for one instance type, you must specify a value for WeightedCapacity for all of them.
        
        Warning
        Every Auto Scaling group has three size parameters ( DesiredCapacity, MaxSize, and MinSize). Usually, you set these sizes based on a specific number of instances. However, if you configure a mixed instances policy that defines weights for the instance types, you must specify these sizes with the same units that you use for weighting instances.
        
        LaunchTemplateSpecification (dict) –
        
        Provides a launch template for the specified instance type or set of instance requirements. For example, some instance types might require a launch template with a different AMI. If not provided, Amazon EC2 Auto Scaling uses the launch template that’s specified in the LaunchTemplate definition. For more information, see Specifying a different launch template for an instance type in the Amazon EC2 Auto Scaling User Guide.
        
        You can specify up to 20 launch templates per Auto Scaling group. The launch templates specified in the overrides and in the LaunchTemplate definition count towards this limit.
        
        LaunchTemplateId (string) –
        
        The ID of the launch template. To get the template ID, use the Amazon EC2 DescribeLaunchTemplates API operation. New launch templates can be created using the Amazon EC2 CreateLaunchTemplate API.
        
        Conditional: You must specify either a LaunchTemplateId or a LaunchTemplateName.
        
        LaunchTemplateName (string) –
        
        The name of the launch template. To get the template name, use the Amazon EC2 DescribeLaunchTemplates API operation. New launch templates can be created using the Amazon EC2 CreateLaunchTemplate API.
        
        Conditional: You must specify either a LaunchTemplateId or a LaunchTemplateName.
        
        Version (string) –
        
        The version number, $Latest, or $Default. To get the version number, use the Amazon EC2 DescribeLaunchTemplateVersions API operation. New launch template versions can be created using the Amazon EC2 CreateLaunchTemplateVersion API. If the value is $Latest, Amazon EC2 Auto Scaling selects the latest version of the launch template when launching instances. If the value is $Default, Amazon EC2 Auto Scaling selects the default version of the launch template when launching instances. The default value is $Default.
        
        InstanceRequirements (dict) –
        
        The instance requirements. Amazon EC2 Auto Scaling uses your specified requirements to identify instance types. Then, it uses your On-Demand and Spot allocation strategies to launch instances from these instance types.
        
        You can specify up to four separate sets of instance requirements per Auto Scaling group. This is useful for provisioning instances from different Amazon Machine Images (AMIs) in the same Auto Scaling group. To do this, create the AMIs and create a new launch template for each AMI. Then, create a compatible set of instance requirements for each launch template.
        
        Note
        If you specify InstanceRequirements, you can’t specify InstanceType.
        
        VCpuCount (dict) –
        
        The minimum and maximum number of vCPUs for an instance type.
        
        Min (integer) –
        
        The minimum number of vCPUs.
        
        Max (integer) –
        
        The maximum number of vCPUs.

        For instance types with Intel CPUs, specify intel.
        
        For instance types with AMD CPUs, specify amd.
        
        For instance types with Amazon Web Services CPUs, specify amazon-web-services.
        
        Note
        Don’t confuse the CPU hardware manufacturer with the CPU hardware architecture. Instances will be launched with a compatible CPU architecture based on the Amazon Machine Image (AMI) that you specify in your launch template.
        
        Default: Any manufacturer
        
        (string) –
        
        MemoryGiBPerVCpu (dict) –

        Max (float) –
        
        The memory maximum in GiB.
        
        ExcludedInstanceTypes (list) –
        
        The instance types to exclude. You can use strings with one or more wild cards, represented by an asterisk ( *), to exclude an instance family, type, size, or generation. The following are examples: m5.8xlarge, c5*.*, m5a.*, r*, *3*.
        
        For example, if you specify c5*, you are excluding the entire C5 instance family, which includes all C5a and C5n instance types. If you specify m5a.*, Amazon EC2 Auto Scaling will exclude all the M5a instance types, but not the M5n instance types.
        
        Note
        If you specify ExcludedInstanceTypes, you can’t specify AllowedInstanceTypes.
        
        Default: No excluded instance types
        
        (string) –
        
        InstanceGenerations (list) –
        
        Indicates whether current or previous generation instance types are included.
        
        For current generation instance types, specify current. The current generation includes EC2 instance types currently recommended for use. This typically includes the latest two to three generations in each instance family. For more information, see Instance types in the Amazon EC2 User Guide for Linux Instances.
        
        For previous generation instance types, specify previous.
        
        Default: Any current or previous generation
        
        (string) –
        
        SpotMaxPricePercentageOverLowestPrice (integer) –
        
        [Price protection] The price protection threshold for Spot Instances, as a percentage higher than an identified Spot price. The identified Spot price is the price of the lowest priced current generation C, M, or R instance type with your specified attributes. If no current generation C, M, or R instance type matches your attributes, then the identified price is from either the lowest priced current generation instance types or, failing that, the lowest priced previous generation instance types that match your attributes. When Amazon EC2 Auto Scaling selects instance types with your attributes, we will exclude instance types whose price exceeds your specified threshold.
        
        The parameter accepts an integer, which Amazon EC2 Auto Scaling interprets as a percentage.
        
        If you set DesiredCapacityType to vcpu or memory-mib, the price protection threshold is based on the per-vCPU or per-memory price instead of the per instance price.
        
        Note
        Only one of SpotMaxPricePercentageOverLowestPrice or MaxSpotPriceAsPercentageOfOptimalOnDemandPrice can be specified. If you don’t specify either, Amazon EC2 Auto Scaling will automatically apply optimal price protection to consistently select from a wide range of instance types. To indicate no price protection threshold for Spot Instances, meaning you want to consider all instance types that match your attributes, include one of these parameters and specify a high value, such as 999999.
        
        MaxSpotPriceAsPercentageOfOptimalOnDemandPrice (integer) –
        
        [Price protection] The price protection threshold for Spot Instances, as a percentage of an identified On-Demand price. The identified On-Demand price is the price of the lowest priced current generation C, M, or R instance type with your specified attributes. If no current generation C, M, or R instance type matches your attributes, then the identified price is from either the lowest priced current generation instance types or, failing that, the lowest priced previous generation instance types that match your attributes. When Amazon EC2 Auto Scaling selects instance types with your attributes, we will exclude instance types whose price exceeds your specified threshold.
        
        The parameter accepts an integer, which Amazon EC2 Auto Scaling interprets as a percentage.
        
        If you set DesiredCapacityType to vcpu or memory-mib, the price protection threshold is based on the per-vCPU or per-memory price instead of the per instance price.
        
        Note
        Only one of SpotMaxPricePercentageOverLowestPrice or MaxSpotPriceAsPercentageOfOptimalOnDemandPrice can be specified. If you don’t specify either, Amazon EC2 Auto Scaling will automatically apply optimal price protection to consistently select from a wide range of instance types. To indicate no price protection threshold for Spot Instances, meaning you want to consider all instance types that match your attributes, include one of these parameters and specify a high value, such as 999999.
        
        OnDemandMaxPricePercentageOverLowestPrice (integer) –
        
        [Price protection] The price protection threshold for On-Demand Instances, as a percentage higher than an identified On-Demand price. The identified On-Demand price is the price of the lowest priced current generation C, M, or R instance type with your specified attributes. If no current generation C, M, or R instance type matches your attributes, then the identified price is from either the lowest priced current generation instance types or, failing that, the lowest priced previous generation instance types that match your attributes. When Amazon EC2 Auto Scaling selects instance types with your attributes, we will exclude instance types whose price exceeds your specified threshold.
        
        The parameter accepts an integer, which Amazon EC2 Auto Scaling interprets as a percentage.
        
        To turn off price protection, specify a high value, such as 999999.
        
        If you set DesiredCapacityType to vcpu or memory-mib, the price protection threshold is applied based on the per-vCPU or per-memory price instead of the per instance price.
        
        Default: 20
        
        BareMetal (string) –
        
        Indicates whether bare metal instance types are included, excluded, or required.
        
        Default: excluded
        
        BurstablePerformance (string) –

        For example, if you specify c5*, Amazon EC2 Auto Scaling will allow the entire C5 instance family, which includes all C5a and C5n instance types. If you specify m5a.*, Amazon EC2 Auto Scaling will allow all the M5a instance types, but not the M5n instance types.
        
        Note
        If you specify AllowedInstanceTypes, you can’t specify ExcludedInstanceTypes.
        
        Default: All instance types
        
        (string) –
      - InstancesDistribution (dict) –
        
        The instances distribution.
        
        OnDemandAllocationStrategy (string) –
        
        The allocation strategy to apply to your On-Demand Instances when they are launched. Possible instance types are determined by the launch template overrides that you specify.
        
        The following lists the valid values:
        
        lowest-price
        
        Uses price to determine which instance types are the highest priority, launching the lowest priced instance types within an Availability Zone first. This is the default value for Auto Scaling groups that specify InstanceRequirements.
        
        prioritized
        
        You set the order of instance types for the launch template overrides from highest to lowest priority (from first to last in the list). Amazon EC2 Auto Scaling launches your highest priority instance types first. If all your On-Demand capacity cannot be fulfilled using your highest priority instance type, then Amazon EC2 Auto Scaling launches the remaining capacity using the second priority instance type, and so on. This is the default value for Auto Scaling groups that don’t specify InstanceRequirements and cannot be used for groups that do.
        
        OnDemandBaseCapacity (integer) –
        
        The minimum amount of the Auto Scaling group’s capacity that must be fulfilled by On-Demand Instances. This base portion is launched first as your group scales.
        
        This number has the same unit of measurement as the group’s desired capacity. If you change the default unit of measurement (number of instances) by specifying weighted capacity values in your launch template overrides list, or by changing the default desired capacity type setting of the group, you must specify this number using the same unit of measurement.
        
        Default: 0
        
        OnDemandPercentageAboveBaseCapacity (integer) –
        
        Controls the percentages of On-Demand Instances and Spot Instances for your additional capacity beyond OnDemandBaseCapacity. Expressed as a number (for example, 20 specifies 20% On-Demand Instances, 80% Spot Instances). If set to 100, only On-Demand Instances are used.
        
        Default: 100
        
        SpotAllocationStrategy (string) –
        
        The allocation strategy to apply to your Spot Instances when they are launched. Possible instance types are determined by the launch template overrides that you specify.
        
        The following lists the valid values:
        
        capacity-optimized
        
        Requests Spot Instances using pools that are optimally chosen based on the available Spot capacity. This strategy has the lowest risk of interruption. To give certain instance types a higher chance of launching first, use capacity-optimized-prioritized.
        
        capacity-optimized-prioritized
        
        You set the order of instance types for the launch template overrides from highest to lowest priority (from first to last in the list). Amazon EC2 Auto Scaling honors the instance type priorities on a best effort basis but optimizes for capacity first. Note that if the On-Demand allocation strategy is set to prioritized, the same priority is applied when fulfilling On-Demand capacity. This is not a valid value for Auto Scaling groups that specify InstanceRequirements.
        
        lowest-price
        
        Requests Spot Instances using the lowest priced pools within an Availability Zone, across the number of Spot pools that you specify for the SpotInstancePools property. To ensure that your desired capacity is met, you might receive Spot Instances from several pools. This is the default value, but it might lead to high interruption rates because this strategy only considers instance price and not available capacity.
        
        price-capacity-optimized (recommended)
        
        The price and capacity optimized allocation strategy looks at both price and capacity to select the Spot Instance pools that are the least likely to be interrupted and have the lowest possible price.
        
        SpotInstancePools (integer) –
        
        The number of Spot Instance pools across which to allocate your Spot Instances. The Spot pools are determined from the different instance types in the overrides. Valid only when the SpotAllocationStrategy is lowest-price. Value must be in the range of 1–20.
        
        Default: 2
        
        SpotMaxPrice (string) –
        
        The maximum price per unit hour that you are willing to pay for a Spot Instance. If your maximum price is lower than the Spot price for the instance types that you selected, your Spot Instances are not launched. We do not recommend specifying a maximum price because it can lead to increased interruptions. When Spot Instances launch, you pay the current Spot price. To remove a maximum price that you previously set, include the property but specify an empty string (“”) for the value.
        
        Warning
        If you specify a maximum price, your instances will be interrupted more frequently than if you do not specify one.
