Bug 638268 – app-emulation/docker-17.10.0: service start fails

• Product: Gentoo Linux
• Status: RESOLVED OBSOLETE

[Description Andriy Utkin (RETIRED) 2017-11-20 19:41:18 UTC]

Reproduces with app-emulation/docker-17.10.0 and older.

Postinst doesn't complain about any missing kernel config options.

Workaround: comment out "ulimit -n 1048576" in start_pre(). I don't know why this helps.

Another workaround is to start "dockerd" directly from shell, or directly via start-stop-daemon, which is what init script implicitly does, I suppose:

/sbin/start-stop-daemon --start --exec /usr/bin/dockerd --pidfile /run/docker.pid --verbose --background --stderr /var/log/docker-err.log --stdout /var/log/docker-out.log -- -p /run/docker.pid

reopen if still actual.
