Just writing down what I asked myself this morning: what is the best way to update running docker images?

• watchtower - it uses polling, so either we ask it to poll docker-hub every minute and trigger docker-hub's DOS protection (like I did), or we wait for 1h for it to update. Well, byzcoin updates once a week, so that's probably OK. But for short update cycles it doesn't shine
• ssh prod bash -c "docker-compose down; docker-compose pull; docker-compose up -d" in a github-workflow - well, it works, but still feels bad. You have to create an ssh-keypair (or take your personal one ;) and install the public one in github

Are there any other options?

As watchtower hits rate limiting, the ~best one is to trigger update ourself, via ssh.

I don't think so. I know of some way using kubernetes which triggers deployement when a new image is build but only for its own containers.
