When you self-host things you often use Docker. And when you are responsible for things running with Docker how do you keep things updated?
One answer to this used to be watchtower, a daemon that updated your docker packages. BUT … it’s abandoned. So I wrote a slightly better replacement called Mangrullo
Crystal + Kemal + Docr + Other things as usual :-)
Noice, been kinda missing a watchtower replacement.
Sidenote: anyone knows of a Crystal Docker shard that allows for listening on events?
What kind of events?
Container start/stop/die primarily.
You can just run docker events --filter type=container --filter event=start and look at the output or something. Surely there is also a REST endpoint in the socket … maybe docr can be expanded to support it
