describe-servers¶

Description¶

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.

Synopsis¶

  describe-servers
[--server-name <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options¶

--server-name (string)

Describes the server with the specified ServerName.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Examples¶

To describe servers

The following describe-servers command returns information about all servers that are associated with your account, and in your default region.:

aws opsworks-cm describe-servers

The output for each server entry returned by the command resembles the following. Output:

{
 "Servers": [
    {
       "BackupRetentionCount": 8,
       "CreatedAt": 2016-07-29T13:38:47.520Z,

Output¶

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 Server: DescribeServersResponse$Servers$EngineAttributes contains PUPPET_API_CA_CERT. This is 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.

(structure)

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 -> (timestamp)

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.

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.
