• "upgrade_os_to" - Specifies the desired Amazon Linux version for instances whose OS you want to upgrade, such as Amazon Linux 2016.09. You must also set the "allow_reboot" argument to true.
• "allow_reboot" - Specifies whether to allow AWS OpsWorks Stacks to reboot the instances if necessary, after installing the updates. This argument can be set to either "true" or "false". The default value is "false".

For example, to upgrade an instance to Amazon Linux 2016.09, set "Args" to the following.

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.
