Create Docker image(s)
======================

If you are creating an operator for an OpenStack component or another project that does not provide a docker container,
or if you need to modify the base image of an existing container, you first need to create a new project with a Dockerfile under https://gitlab.com/yaook/images.

You can use a repository like `Barbican <https://gitlab.com/yaook/images/barbican>`__ as a reference. 
To determine which UID and GID to use inside the Dockerfile, increment the ID of the last entry from the table inside :doc:`../../explanations/containers`.

Make sure you also add the following to the repository:

* ``gitlab-ci.yaml`` with the following jobs:

  * linting:

    * shell linting if the repository includes shell fixes
    * Dockerfile linting [1]_

  * Docker build and push
  * Docker manifest creation
  * a test case to verify port connectivity to a running container
  * version bumping
* default policy files (see :doc:`../openstack_policies`)
* `LICENSE <https://www.apache.org/licenses/LICENSE-2.0.txt>`__ file of the Apache License


.. [1] Regardless that it is not implemented in other repositories yet.
