Ubuntu
docker.io package

docker logs doesnt work with log-driver=journald

Asked by Andor

There are multiple bug reports where log-driver=journald doesn't support read via command `docker logs` and command `kubectl logs` if you are using kubernetes on top of docker.
Everywhere docker developers suggest to remove `docker.io` package and install their build package.
Maybe you can suggest a better solution for this problem? Maybe some option can help with this issue?

I used strace (strace -s 1024 -fp 4551) on running dockerd from docker.io-17.12.1-0ubuntu1 package to diagnose a problem and found this:
