Set of semantic-release plugins for publishing a docker image to Docker Hub.

{
  "release": {
    "verifyConditions": {
      "path": "semantic-release-docker",
      "registryUrl": "docker.io"
    },
    "publish": {
      "path": "semantic-release-docker",
      "name": "username/imagename"
    }
  }
}

Configuration

Your credentials have to be configured with the environment variables DOCKER_USERNAME and DOCKER_PASSWORD.

In addition, you need to specify the name of the image as the name setting in the publish step. If you need to specify a custom docker registry URL, add it as the registryUrl setting in the verifyConditions step.

Plugins

`verifyConditions`

Verify that all needed configuration is present and login to the Docker registry.

`publish`

Tag the image specified by name with the new version, push it to Docker Hub and update the latest tag.
