Scriptworker Readme

Scriptworker implements the TaskCluster worker model, then launches a pre-defined script.

This worker was designed for Releng processes that need specific, limited, and pre-defined capabilities.

Usage

• Create a config file. By default scriptworker will look in ./scriptworker.yaml, but this config path can be specified as the first and only commandline argument. There is an example config file, and all config items are specified in scriptworker.constants.DEFAULT_CONFIG.

Credentials can live in ./scriptworker.yaml, ./secrets.json, ~/.scriptworker, or in environment variables: TASKCLUSTER_ACCESS_TOKEN, TASKCLUSTER_CLIENT_ID, and TASKCLUSTER_CERTIFICATE.

• Launch: scriptworker [config_path]

Testing

Without integration tests, install tox, then

NO_CREDENTIALS_TESTS=1 tox -e py36

Without any tests connecting ot the net, then

NO_TESTS_OVER_WIRE=1 tox -e py36

With integration tests, first create a client with the scopes:

queue:cancel-task:test-dummy-scheduler/*
queue:claim-work:test-dummy-provisioner/dummy-worker-*
queue:create-task:lowest:test-dummy-provisioner/dummy-worker-*
queue:define-task:test-dummy-provisioner/dummy-worker-*
queue:get-artifact:SampleArtifacts/_/X.txt
queue:scheduler-id:test-dummy-scheduler
queue:schedule-task:test-dummy-scheduler/*
queue:task-group-id:test-dummy-scheduler/*
queue:worker-id:test-dummy-workers/dummy-worker-*

Then create a ./secrets.json or ~/.scriptworker that looks like:

{
    "integration_credentials": {
        "clientId": "...",
        "accessToken": "...",
        "certificate": "..."
    }
}

(certificate is only specified if using temp creds)

then

tox
