A Concourse resource to deploy applications to Marathon.

Source Configuration

• app_id: Required. The name of your app in Marathon.

• uri: Required. The URI of the Marathon instance you wish to deploy to.

• basic_auth: Optional. Use if you are using HTTP Basic Auth to protect your Marathon instance. Takes user_name and password

• api_token: Optional. Use if you are using DC/OS and need to set an HTTP API token.

Behavior

check: Extract versions of an app from Marathon.

Returns a list of any versions greater than or equal the last know version of the app defined by app_id.

in: Fetch data about the current version of an app.

Returns JSON description of the current running version of the app.

Parameters

None.

out: Deploy an app to Marathon.

Given a JSON file specified by app_json, post it to Marathon to deploy the app. The resource will cancel the deployment if its not successful after time_out.

Parameters

• app_json: Required. Path to the JSON file describing your marathon app. For more information about the format see the Marathon docs.

• time_out: Required. How long, in seconds, to wait for Marathon to deploy the app. Timed out deployments will roll back and fail the job.

• replacements: Optional. A name/value list of templated strings in the app.json to replace during the deploy. Useful for things such as passwords or urls that change.

• replacement_files: Optional. Similar to replacements except value is a path to a file who's content will be used in the replace.

• restart_if_no_update: Optional. If Marathon doesn't detect any change in your app.json it won't deploy a new version. Setting this to true will restart an existing app causing a new version. Default is false.
