watchtower won't check other containers than itself

[kingzleshe]

The logs shows
"No, pull needed. Skipping image "1 scanned, 0 updated, 0 failed"

It that has something to do with my other containers pulled by docker-compose？

my mistake
the docker run only check watchtower

[piksel]

As it says in the startup message:

Only checking containers with name "storj" or "watchtower"

This is because you specified that in the command:
containrrr/watchtower --debug storj watchtower --stop-timeout 300s --interval 8

If you just remove those two, watchtower will check all running containers.

Since only one container is checked, my guess is that there are no containers with the name storj running?
