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 for Chef Automate 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.

See also: AWS API Documentation

Synopsis

  describe-servers
[--server-name <value>]
[--next-token <value>]
[--max-results <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--server-name (string)

Describes the server with the specified ServerName.

--next-token (string)

next-token is a string that is returned in some command responses. It indicates that not all entries have been returned, and that you must run at least one more request to get remaining items. To get remaining results, call describe-servers again, and assign the token from the previous results as the value of the nextToken parameter. If there are no more results, the response object's nextToken parameter value is null . Setting a nextToken value that was not returned in your previous results causes an InvalidNextTokenException to occur.

--max-results (integer)

To receive a paginated response, use this parameter to specify the maximum number of results to be returned with a single call. If the number of available results exceeds this maximum, the response includes a next-token value that you can assign to the next-token request parameter to get the next set of results.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

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 describe-servers request.

(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.

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

Engine -> (string)

The engine type of the server. The valid value in this release is Chef .

EngineModel -> (string)

The engine model of the server. The valid value in this release is Single .

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 for Chef Automate; they are returned only as part of the result of createServer().

Attributes returned in a createServer response:
  • CHEF_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.

(structure)

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. Because Chef is the engine available in this release, the valid value for EngineVersion is 12 .

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.

PreferredBackupWindow -> (string)

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)

ServiceRoleArn -> (string)

The service role ARN used to create the server.

Status -> (string)

The server's status. This field displays the states of actions in progress, such as creating, running, or backing up the server, as well as the server's health state.

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)

The subnet IDs specified in a create-server request.

(string)

ServerArn -> (string)

The ARN of the server.

NextToken -> (string)

next-token is a string that is returned in some command responses. It indicates that not all entries have been returned, and that you must run at least one more request to get remaining items. To get remaining results, call describe-servers again, and assign the token from the previous results as the value of the nextToken parameter. If there are no more results, the response object's nextToken parameter value is null . Setting a nextToken value that was not returned in your previous results causes an InvalidNextTokenException to occur.
