I set it to debug at somepoint and forgot maybe? Idk, but why the heck does the default config of the official Docker is to keep all logs, forever, in a single file woth no rotation?
Feels like 101 of log files. Anyway, this explains why my storage recipt grew slowly but unexpectedly.
It’s because with docker you don’t need to do log files. Logging should be to stdout, and you let the host, orchestration framework, or whoever is running the container so logs however they want to. The container should not be writing log files in the first place, containers should be immutable except for core application logic.
Docker stores that stdout per default in a log file in var/lib/docker/containers/…
You can configure the default or override per service. This isn’t something containers should be doing.
At worst it saves in the config folder/volume where persistent stuff should be.
Good point!
