Start watchtower check immediately

[backupandforkacc]

The next check in watchtower is scheduled for the next day. Is there a chance to do a check immediately?

Yes, but not combined with the scheduled updates. Use --run-once to do a scan on startup and then exit.

this leads to:

$ docker start containrrr/watchtower:latest --run-once --name=watchtower2
unknown flag: --run-once

You cannot pass it to docker start.

$ docker run --rm \
    -v /var/run/docker.sock:/var/run/docker.sock \
    containrrr/watchtower \
    --run-once
