public class UpdateInstanceRequest : AmazonOpsWorksRequest

The UpdateInstanceRequest type exposes the following members


Public Method UpdateInstanceRequest()


Public Property AgentVersion System.String Gets and sets the property AgentVersion.

The default AWS OpsWorks agent version. You have the following options:

  • INHERIT - Use the stack's default agent version setting.
  • version_number - Use the specified agent version. This value overrides the stack's default setting. To update the agent version, you must edit the instance configuration and specify a new version. AWS OpsWorks then automatically installs that version on the instance.

The default setting is INHERIT. To specify an agent version, you must use the complete version number, not the abbreviated number shown on the console. For a list of available agent version numbers, call DescribeAgentVersions.

Public Property AmiId System.String Gets and sets the property AmiId.

A custom AMI ID to be used to create the instance. The AMI must be based on one of the supported operating systems. For more information, see Instances

If you specify a custom AMI, you must set Os to Custom.
Public Property Architecture Amazon.OpsWorks.Architecture Gets and sets the property Architecture.

The instance architecture. Instance types do not necessarily support both architectures. For a list of the architectures that are supported by the different instance types, see Instance Families and Types.

We strongly recommend using the default value of true, to ensure that your instances have the latest security updates.
