Environment

An array of EnvironmentVariable objects that specify environment variables to be associated with the app. After you deploy the app, these variables are defined on the associated app server instance. For more information, see Environment Variables.

There is no specific limit on the number of environment variables. However, the size of the associated data structure - which includes the variables' names, values, and protected flag values - cannot exceed 20 KB. This limit should accommodate most if not all use cases. Exceeding it will cause an exception with the message, "Environment: is too large (maximum is 20KB)."

If you have specified one or more environment variables, you cannot modify the stack's Chef version.

Type

The app type. Each supported type is associated with a particular layer. For example, PHP applications are associated with a PHP layer. AWS OpsWorks Stacks deploys an application to those instances that are members of the corresponding layer. If your app isn't one of the standard types, or you prefer to implement your own Deploy recipes, specify other.

Required: Yes

Type: String

Allowed values: aws-flow-ruby | java | rails | php | nodejs | static | other

Update requires: No interruption

For the AWS OpsWorks stack myApp, Ref returns the ID of the AWS OpsWorks app.

For more information about using the Ref function, see Ref.
