I updated fedora server 23 to fedora server 25. Everything works fine execpt docker. which is quite bad because i have about 28 containers that should be running right now. I have found out that it could be a problem with SystemD and how the cgroups filesystems get mounted. So i added
GRUB_CMDLINE_LINUX="systemd.legacy_systemd_cgroup_controller=yes"
but it is still not working. In my system logfile i can see some more errors
Jan 30 08:23:50 kindred.one systemd[1]: libcontainer-7475-systemd-test-default-dependencies.scope: Scope has no PIDs. Refusing.
Jan 30 08:23:50 kindred.one systemd[1]: libcontainer-7475-systemd-test-default-dependencies.scope: Scope has no PIDs. Refusing.
but i haven't found anything useful about this error.
this is the error that i get on the terminal.
/usr/bin/docker-current: Error response from daemon: invalid header field value "oci runtime error: container_linux.go:247: starting container process caused \"process_linux.go:334: running prestart hook 1 caused \\\"error running hook: exit status 1, stdout: , stderr: \\\"\"\n".
EDIT:
these are the labels on the docker binaries
system_u:object_r:container_runtime_exec_t:s0
The problem seems related to SELinux labelling. If you don't want to disable SELinux, you have to relabelling your system.
Check the output of
ls -Z1 /usr/bin/docker*
They should be
system_u:object_r:docker_exec_t:s0
It seems you get the same than Bug 1405131 - Docker refuses to start containers (SELINUX).
