update-server-engine-attributes¶

Description¶

Updates engine-specific attributes on a specified server. The server enters the MODIFYING state when this operation is in progress. Only one update can occur at a time. You can use this command to reset a Chef server’s public key (CHEF_PIVOTAL_KEY ) or a Puppet server’s admin password (PUPPET_ADMIN_PASSWORD ).

This operation is asynchronous.

This operation can only be called for servers in HEALTHY or UNHEALTHY states. Otherwise, an InvalidStateException is raised. A ResourceNotFoundException is thrown when the server does not exist. A ValidationException is raised when parameters of the request are not valid.

Synopsis¶

  update-server-engine-attributes
--server-name <value>
--attribute-name <value>
[--attribute-value <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--server-name (string)

The name of the server to update.

--attribute-name (string)

The name of the engine attribute to update.

--attribute-value (string)

The value to set for the attribute.

--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.

--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.

See ‘aws help’ for descriptions of global parameters.

Examples¶

To update server engine attributes

The following update-server-engine-attributes command updates the value of the CHEF_PIVOTAL_KEY engine attribute for a Chef Automate server named automate-06. It is currently not possible to change the value of other engine attributes.

aws opsworks-cm update-server-engine-attributes \
    --attribute-name CHEF_PIVOTAL_KEY \
    --attribute-value "new key value" \
    --server-name "automate-06"

The output shows you information similar to the following about the updated server.

    "Server": {
        "BackupRetentionCount": 2,
        "CreatedAt": 2016-07-29T13:38:47.520Z,

Output¶

Server -> (structure)

Contains the response to an UpdateServerEngineAttributes request.

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.

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.
