Chapter 3. Publishing an automation execution environment

Procedure

1. Log in to registry.redhat.io via Podman:

   $ podman login -u="[username]" -p="[token/hash]" registry.redhat.io

   Copy to Clipboard Toggle word wrap

2. Ensure that you can pull the desired automation execution environment base image

   podman pull registry.redhat.io/ansible-automation-platform-22/ee-minimal-rhel8:latest

   Copy to Clipboard Toggle word wrap

3. Configure your Ansible Builder files to specify the desired base image and any additional content to add to the new execution environment image.

   1. For example, to add the Kubernetes Core Collection from Galaxy to the image, fill out the requirements.yml file as follows:

      collections:
        - kubernetes.core

      Copy to Clipboard Toggle word wrap
   2. For more information on definition files and their content, refer to to definition file breakdown section.

4. In the execution environment definition file, specify the original ee-minimal container’s URL and tag in the EE_BASE_IMAGE field. In doing so, your final execution-environment.yml file will look like the following:

   Example 3.1. A customized execution-environment.yml file

   version: 1
   
   build_arg_defaults:
     EE_BASE_IMAGE: 'registry.redhat.io/ansible-automation-platform-22/ee-minimal-rhel8:latest'
   
   dependencies:
     galaxy: requirements.yml

   Copy to Clipboard Toggle word wrap
   Note

   Since this example uses the community version of kubernetes.core and not a certified collection from automation hub, we do not need to create an ansible.cfg file or reference that in our definition file.

5. Build the new execution environment image using the following command:

   $ ansible-builder build -t registry.redhat.io/[username]/new-ee

   Copy to Clipboard Toggle word wrap

   where [username] specifies your username, and new-ee specifies the name of your new container image.

1. Use the podman images command to confirm that your new container image is in that list:

   Example 3.2. Output of a podman images command with the image new-ee

   REPOSITORY          TAG     IMAGE ID      CREATED        SIZE
   localhost/new-ee    latest  f5509587efbb  3 minutes ago  769 MB

   1. Verify that the collection is installed:

      $ podman run registry.redhat.io/[username]/new-ee ansible-doc -l kubernetes.core

      Copy to Clipboard Toggle word wrap

   2. Tag the image for use in your automation hub:

      $ podman tag registry.redhat.io/[username]/new-ee [automation-hub-IP-address]/[username]/new-ee

   3. Log in to your automation hub using Podman:

      Note

      You must have admin or appropriate container repository permissions for automation hub to push a container. See Managing containers in private automation hub in the Red Hat Ansible Automation Platform documentation for more information.

      $ podman login -u="[username]" -p="[token/hash]" [automation-hub-IP-address]

      Copy to Clipboard Toggle word wrap

   4. Push your image to the container registry in automation hub:

      $ podman push [automation-hub-IP-address]/[username]/new-ee

      Copy to Clipboard Toggle word wrap
   5. Pull your new image into your automation controller instance:
2. Navigate to automation controller.
3. From the side-navigational bar, click Administration Execution Environments.
4. Click Add.

5. Enter the appropriate information then click Save to pull in the new image.

   Note

   If your instance of automation hub is password or token protected, ensure that you have the appropriate container registry credential set up.
