If I understood correctly, he manually runs watchtower to poll rather than leaving it running all the time. What wasn’t clear to me was if he has it doing the updates (evidenced by him saying he cleans up where needed after) or just pull down the updated images and he then manually restarts/rebuilds the container.
I leave it running all the time and it only updates at something like 03:00. The only containers I don’t have set to latest are DBs as major updates tend to break things.
Yes, I’ve set
WATCHTOWER_RUN_ONCEand run it manually (letting it download and automatically apply the updates) when I find time. In the rare case something breaks, I can fix it immediately or roll back the broken container by setting the label to the previous version.Thank you. Side question:
Still a docker noob. I find I have a lot of orphaned images. What do people normally do, schedule a purge or just prune them manually every once in a while?
