OpsWorksCM / Client / describe_servers

describe_servers#

OpsWorksCM.Client.describe_servers(**kwargs)#

Lists all configuration management servers that are identified with your account. Only the stored results from Amazon DynamoDB are returned. AWS OpsWorks CM does not query other services.

This operation is synchronous.

A ResourceNotFoundException is thrown when the server does not exist. A ValidationException is raised when parameters of the request are not valid.

Response Structure

  • (dict) –

    • Servers (list) –

      Contains the response to a DescribeServers request.

      For Chef Automate servers: If DescribeServersResponse$Servers$EngineAttributes includes CHEF_MAJOR_UPGRADE_AVAILABLE, you can upgrade the Chef Automate server to Chef Automate 2. To be eligible for upgrade, a server running Chef Automate 1 must have had at least one successful maintenance run after November 1, 2019.

      For Puppet servers: DescribeServersResponse$Servers$EngineAttributes contains the following two responses:

      • PUPPET_API_CA_CERT, the PEM-encoded CA certificate that is used by the Puppet API over TCP port number 8140. The CA certificate is also used to sign node certificates.

      • PUPPET_API_CRL, a certificate revocation list. The certificate revocation list is for internal maintenance purposes only. For more information about the Puppet certificate revocation list, see Man Page: puppet certificate_revocation_list in the Puppet documentation.

      • (dict) –

        Describes a configuration management server.

        • AssociatePublicIpAddress (boolean) –

          Associate a public IP address with a server that you are launching.

        • BackupRetentionCount (integer) –

          The number of automated backups to keep.

        • ServerName (string) –

          The name of the server.

        • CreatedAt (datetime) –

          Time stamp of server creation. Example 2016-07-29T13:38:47.520Z

        • CloudFormationStackArn (string) –

          The ARN of the CloudFormation stack that was used to create the server.

        • CustomDomain (string) –

          An optional public endpoint of a server, such as https://aws.my-company.com. You cannot access the server by using the Endpoint value if the server has a CustomDomain specified.

        • DisableAutomatedBackup (boolean) –

          Disables automated backups. The number of stored backups is dependent on the value of PreferredBackupCount.

        • Endpoint (string) –

          A DNS name that can be used to access the engine. Example: myserver-asdfghjkl.us-east-1.opsworks.io. You cannot access the server by using the Endpoint value if the server has a CustomDomain specified.

        • Engine (string) –

          The engine type of the server. Valid values in this release include ChefAutomate and Puppet.

        • EngineModel (string) –

          The engine model of the server. Valid values in this release include Monolithic for Puppet and Single for Chef.

        • EngineAttributes (list) –

          The response of a createServer() request returns the master credential to access the server in EngineAttributes. These credentials are not stored by AWS OpsWorks CM; they are returned only as part of the result of createServer().

          Attributes returned in a createServer response for Chef

          • CHEF_AUTOMATE_PIVOTAL_KEY: A base64-encoded RSA private key that is generated by AWS OpsWorks for Chef Automate. This private key is required to access the Chef API.

          • CHEF_STARTER_KIT: A base64-encoded ZIP file. The ZIP file contains a Chef starter kit, which includes a README, a configuration file, and the required RSA private key. Save this file, unzip it, and then change to the directory where you’ve unzipped the file contents. From this directory, you can run Knife commands.

          Attributes returned in a createServer response for Puppet

          • PUPPET_STARTER_KIT: A base64-encoded ZIP file. The ZIP file contains a Puppet starter kit, including a README and a required private key. Save this file, unzip it, and then change to the directory where you’ve unzipped the file contents.

          • PUPPET_ADMIN_PASSWORD: An administrator password that you can use to sign in to the Puppet Enterprise console after the server is online.

          • (dict) –

            A name and value pair that is specific to the engine of the server.

            • Name (string) –

              The name of the engine attribute.

            • Value (string) –

              The value of the engine attribute.

        • EngineVersion (string) –

          The engine version of the server. For a Chef server, the valid value for EngineVersion is currently 2. For a Puppet server, specify either 2019 or 2017.

        • InstanceProfileArn (string) –

          The instance profile ARN of the server.

        • InstanceType (string) –

          The instance type for the server, as specified in the CloudFormation stack. This might not be the same instance type that is shown in the EC2 console.

        • KeyPair (string) –

          The key pair associated with the server.

        • MaintenanceStatus (string) –

          The status of the most recent server maintenance run. Shows SUCCESS or FAILED.

        • PreferredMaintenanceWindow (string) –

          The preferred maintenance period specified for the server.

          The preferred backup period specified for the server.

        • SecurityGroupIds (list) –

          The security group IDs for the server, as specified in the CloudFormation stack. These might not be the same security groups that are shown in the EC2 console.

          • (string) –

        • StatusReason (string) –

          Depending on the server status, this field has either a human-readable message (such as a create or backup error), or an escaped block of JSON (used for health check results).

        • SubnetIds (list) –
