name

Specifies the operation. You can specify only one command.

For stacks, the following commands are available:

• execute_recipes: Execute one or more recipes. To specify the recipes, set an Args parameter named recipes to the list of recipes to be executed. For example, to execute phpapp::appsetup, set Args to {"recipes":["phpapp::appsetup"]}.

• install_dependencies: Install the stack's dependencies.

• update_custom_cookbooks: Update the stack's custom cookbooks.

• update_dependencies: Update the stack's dependencies.

The update_dependencies and install_dependencies commands are supported only for Linux instances. You can run the commands successfully on Windows instances, but they do nothing.

For apps, the following commands are available:

• deploy: Deploy an app. Ruby on Rails apps have an optional Args parameter named migrate. Set Args to {"migrate":["true"]} to migrate the database. The default setting is {"migrate":["false"]}.

• rollback Roll the app back to the previous version. When you update an app, AWS OpsWorks Stacks stores the previous version, up to a maximum of five versions. You can use this command to roll an app back as many as four versions.

• start: Start the app's web or application server.

• stop: Stop the app's web or application server.

• restart: Restart the app's web or application server.

• undeploy: Undeploy the app.
