Unable to find process isolation executable: podman on AAP/AWX

Get Help

OK, I know I am a Red Hat employee, but I need help, and I assume other folks will hit this, so I would rather get help online, in the open, so everyone will benefit when someone helps me out :pray:

I routinely will build images for AAP using the containerized installer, then use these images in labs and workshps, and everything installs fine. But “SOMETIMES” I will get this error when trying to sync a project (through the infra.controller content collection, which uses the awx.awx content collection).

Worker output:
Unable to find process isolation executable: podman

If I login to the webUI, and manually sync the project, everything will work fine… and there is no errors.

I have a feeling… (guess) that it has something to do with when I issue an SSL cert.

I will do something like this->

- name: Make sure Automation Controller is stopped
  become: true
  become_user: "{{ run_commands_user }}"
  containers.podman.podman_container:
    name: automation-controller-web
    state: stopped
  register: install_controller
  until: install_controller is not failed
  retries: 5

I then let Let’s Encrypt create a cert (it sets up an https website using the certbot package, retrieves the cert, then deletes the web service).

Then turn Automation controller back on later->

- name: Make sure Automation Controller is online before changing base URL
  become: true
  become_user: "{{ run_commands_user }}"
  containers.podman.podman_container:
    name: automation-controller-web
    state: started
  register: install_controller
  until: install_controller is not failed
  retries: 5

I am curious… if I should be doing that with all these containers…

[ec2-user@ansible-1 ~]$ podman ps

so there is actually 6 containers… should I be restarting all of these rather than just the web? or if my hypothesis is just off…

I also have tried a block/rescue to and until loops… but once it hits this podman error, I can’t seem to bypass it unless I manually login to the webUI. It is hair pulling furstrating…

That error comes from ansible-runner. That error is only going to happen when runner cannot successfully execute the podman --version command and shouldn’t have anything to do with SSL certs. I suspect you might be hitting a worker node that somehow doesn’t have podman installed? Or perhaps a broken installation?

as soon as I login to the webUI, the project syncs successfully, and I never see that error again… podman exists fine

Sean do you have a snippet that just uses awx.awx.collection that I can try to reproduce the problem with?

also is that worker output error message on the stdout page of the project sync in the UI?

I cannot reliabley recreate this, but here is when it happened last time from the POV from my control node provisioning the AWX host on AWS:

the workshop will use the infra.controller validated content collection role->

 - infra.controller_configuration.projects

which is basically doing this->

- name: Add project
  awx.awx.project:
    name: "Our Project"
    organization: "Default"
    scm_type: git
    scm_url: "https://github.com/redhat-partner-tech/automated-satellite.git"
    execution_environment: "quay.io/s4v0/ee-automated-satellite-aap2:2.0.0"
    scm_branch: 'aap2-24'

when we login we see the podman error… but when we manually press sync on the webUI it just works… and no other problems are reported… it is very weird…

We encountered this issue on containerized AAP 2.5 today and a reboot resolved it.
