Stuck on starting a rootless container...

[74razor]

Hoping someone can point me in the right direction with starting a rootless container on start-up. I'm following Sanders certification guide but not getting the expected results. Here are my steps:

podman login (enter RH account creds)
podman pull ubi8
podman run -dt --name rhel8 ubi8
mkdir ~/.config/systemd/user; cd ~/.config/systemd/user
podman generate systemd --name rhel8 --files
I vim into the container-rhel8.service file and change the line to read WantedBy=default.target
systemctl --user daemon-reload
loginctl enable-linger user1
systemctl --user --now enable container-rhel8.servicebut it errors out:
Job for container-rhel8.service failed because the control process exited with error code.
See "systemctl --user status container-rhel8.service" and "journalctl --user -xe" for details.

[user1@rhcsa2 user]$ journalctl --user -xe

I went through this chapter and things make sense. I 'should' work... but I must be missing something.

Ok, I think this is because I used 'systemctl --user --now enable container-rhel8.service' when the container was already running. I tried it on another VM with just 'systemctl --user enable container-rhel8.service' and it worked fine.

Hey, try this:

1. podman generate systemd --name rhel8 --files --new
2. stop and remove the cointainer via podman command
3. enable and start you rootless container

I hope this can help.

I see you've solved this but wanted to mention that it is not necessary to add the WantedBy by hand. That is what the systemctl --user --enable does.

In my opinion the Guided Exercise: Managing Containers as Services has a better overview of the steps required than the preceding chapter.
