start_maintenance(**kwargs)¶Manually starts server maintenance. This command can be useful if an earlier maintenance attempt failed, and the underlying cause of maintenance failure has been resolved. The server is in an UNDER_MAINTENANCE state while maintenance is in progress.
Maintenance can only be started on servers in HEALTHY and UNHEALTHY states. Otherwise, an InvalidStateException is thrown. 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) --
Server (dict) --
Contains the response to a StartMaintenance 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 (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) --
