title: Automatically Updating Podman Containers
|
|
---
|
|
|
|
Recently, I have been [transitioning to Podman](/blog/rootless-docker-compose-podman/) for running my container infrastructure. In the process, I brought over Watchtower which I have previously used for auto-updating docker containers. Before doing so, I didn't check its [compatibility](https://github.com/containrrr/watchtower/issues/1060) (whoops) and found a few of my containers would every other week or so not come back up.
|
|
|
|
I then remembered that I restart my server for general system updates almost every day. What if I perform the podman container updates on start up? After modiyfing my systemd service to include an extra field called `ExecStartPre` and removing Watchtower, I found no more missing containers! The field `ExecStartPre` performs a pull (update) before starting up the containers via `ExecStart`.
