Custom Configuration

Important

AWS OpsWorks Stacks is no longer accepting new customers. Existing customers will be able to use the OpsWorks console, API, CLI, and CloudFormation resources as normal until May 26, 2024, at which time they will be discontinued. To prepare for this transition, we recommend you transition your stacks to AWS Systems Manager as soon as possible. For more information, see AWS OpsWorks Stacks End of Life FAQs and Migrating your AWS OpsWorks Stacks applications to AWS Systems Manager Application Manager.

AWS OpsWorks Stacks exposes additional configuration settings as built-in attributes, which are all in the opsworks_java namespace. You can use custom JSON or a custom attributes file to override the built-in attributes and specify custom values. For example, the JVM and Tomcat versions are represented by the built-in jvm_version and java_app_server_version attributes, both of which are set to 7. You can use custom JSON or a custom attributes file to set either or both to 6. The following example uses custom JSON to set both attributes to 6:

{
  "opsworks_java": {
    "jvm_version": 6,
    "java_app_server_version" : 6
  }
}

For more information, see Using Custom JSON.

Another example of custom configuration is installing a custom JDK by overriding the use_custom_pkg_location, custom_pkg_location_url_debian, and custom_pkg_location_url_rhel attributes.

Note

If you override the built-in cookbooks, you will need to update those components yourself.
