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.
