Running a Skill in a Docker Desktop Extension

The following files are needed to turn a Docker Desktop extension into a skill:

• datalog - datalog subscriptions
• skill.yaml - skill metadata
• Dockerfile - copying skill.yaml and datalog into the file system root of the final image; add the com.docker.skill.api.version="extension/v2" label
• Add @atomist/[email protected] to your dependencies

With these changes in place, you can now call subscribe in your Extension UI:

  skill.subscribe({
    namespace: "atomist",
    name: "skill-extension",
    apiKey: "<api key>",
    workspaceId: "<workspace id>",
    debug: true,
  }, {"new_issue": async ctx => {
    setResponse(JSON.stringify(ctx.event.context.subscription.result[0][0]));
    return skill.status.completed("Handled new issue event");
  }}, require("pusher-js/with-encryption"));

In order to register the extension as skill, you need to docker build and push the image to your Docker registry and make sure that the image is visible in your Atomist workspace. When we transact the image, we'll discover the skill metadata and register the skill.

Once it is build and registered, navigate to https://skills.dso.docker.com/catalog/skills/atomist/skill-extension?stability=unstable and enable your skill.
