3.4.0 images should default to `log.output` of `-` (stdout) #62

Closed rocketraman closed 5 years ago

rocketraman commented 5 years ago

I upgraded my cluster from 3.3.x to 3.4.1 I actually thought the upgrade failed (see https://github.com/arangodb/arangodb/issues/7914) because the default log output of a 3.4.1 cluster goes to a file (see /etc/arangodb/arang). The echo messages from the init script do show up on stdout, so if one is looking at the container logs, it seems like the server has just hung, when in fact it is likely starting normally.

I do see https://github.com/arangodb/arangodb-docker/blob/c77fa2b9bca45deb37e2a709dead1147541857ba/alpine/3.4.1/Dockerfile#L30 is intended to set the output to standard output but as you can see, it does not appear to be working:

$ kubectl exec -it arangodb-db-0 --namespace default grep "file =" /tmp/arangod.conf
file = /var/log/arangodb3/arangod.log

Temporary fix is to start container with CMD: "--log.output -".

Note: the _/arangodb container shouldn't be doing this, only the arangodb/arangodb one.
