Chapter 4. Publishing an automation execution environment

Procedure

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

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

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

   podman pull registry.redhat.io/ansible-automation-platform-26/ee-minimal-rhel8:latest

3. Configure your Ansible Builder files to specify the required 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, use the Galaxy entry:

      collections:
        - kubernetes.core

   2. For more information about definition files and their content, see the Breakdown of definition file content 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 looks similar to the following:

   version: 3
   
   images:
     base_image:
       name: 'registry.redhat.io/ansible-automation-platform-25/ee-minimal-rhel9:latest'
   
   dependencies:
     galaxy:
       collections:
         - kubernetes.core

   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 by using the following command:

   $ ansible-builder build -t [username]/new-ee

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

   Note

   If you do not use -t with build, an image called ansible-execution-env is created and loaded into the local container registry.

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

     The following shows the 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

6. Verify that the collection is installed:

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

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

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

8. 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. For more information, see Manage containers in private automation hub.

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

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

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

10. Pull your new image into your automation controller instance:

    1. Go to automation controller.
    2. From the navigation panel, select Automation Execution Infrastructure Execution Environments.
    3. Click Add.

    4. 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.
