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 🙏 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). ![image](https://us1.discourse-cdn.com/ansible/original/2X/1/1ec0157e48712a5863f1e71d461124515d7734df.png) ```auto 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-\> ```auto - 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-\> ```auto - 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… ```auto [ec2-user@ansible-1 ~]$ podman ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES a5dd9747001b registry.redhat.io/rhel8/postgresql-13:latest run-postgresql 6 weeks ago Up 25 minutes postgresql 462fc9c41346 registry.redhat.io/rhel8/redis-6:latest run-redis 6 weeks ago Up 25 minutes redis a9bed32cb9f5 registry.redhat.io/ansible-automation-platform-24/ee-supported-rhel8:latest /usr/bin/receptor... 6 weeks ago Up 25 minutes receptor 714348cda22c registry.redhat.io/ansible-automation-platform-24/controller-rhel8:latest /usr/bin/launch_a... 6 weeks ago Up 25 minutes automation-controller-rsyslog e606bb5e6231 registry.redhat.io/ansible-automation-platform-24/controller-rhel8:latest /usr/bin/launch_a... 6 weeks ago Up 25 minutes automation-controller-task d37e4e346fbe registry.redhat.io/ansible-automation-platform-24/controller-rhel8:latest /usr/bin/launch_a... 6 weeks ago Up 21 minutes automation-controller-web ``` 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: ```auto TASK [infra.controller_configuration.projects : Configure Controller Projects | Wait for finish the projects creation] ************************************* Wednesday 29 November 2023 15:40:59 -0800 (0:00:06.092) 0:25:29.196 **** FAILED - RETRYING: [nov29-student1-ansible-1]: Configure Controller Projects | Wait for finish the projects creation (45 retries left).

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