Update Containers

How to properly upgrade a container the Docker way (also the podman way).

1. Update container
   podman pull docker.io/path/to/application

2. Stop old container and remove it
   podman stop containername
podman rm containername

3. Start it back up using the full run line for that specific container from when you initially set it up.
   podman run -d ...

4. Done!

Example:

SSH into your UDM-Pro. Below is an example using the above method. Ignore the errors.

podman pull pihole/pihole

Trying to pull docker.io/pihole/pihole...
