Created attachment 1421026 [details] log from docker-systemd failure # docker run -t registry.access.redhat.com/rhel7/rhel:latest /usr/sbin/init systemd 219 running in system mode. (+PAM +AUDIT +SELINUX +IMA -APPARMOR +SMACK +SYSVINIT +UTMP +LIBCRYPTSETUP +GCRYPT +GNUTLS +ACL +XZ -LZ4 -SECCOMP +BLKID +ELFUTILS +KMOD +IDN) ... [ OK ] Reached target Encrypted Volumes. Failed to create cgroup /system.slice/docker-<sha>.scope/system.slice/systemd-journald.service: Permission denied .... Lots and lots of these. See attachment for full log. RPMs of note: kernel-3.10.0-862.el7.x86_64 docker-1.13.1-58.git87f2fab.el7.x86_64 container-selinux-2.55-1.el7.noarch selinux-policy-3.13.1-192.el7_5.3.noarch This is RHEL 7.4 with latest updates; I haven't seen it fail on RHEL 7.5 (!) Under the previous 7.4 kernel (kernel-3.10.0-693.el7.x86_64), before rebooting, the error was quicker: Set hostname to <7381be6f2c57>. Initializing machine ID from random generator. Failed to create root cgroup hierarchy: Permission denied Failed to allocate manager object: Permission denied [!!!!!!] Failed to allocate manager object, freezing. AFAICT RHEL 7.4 only, not 7.5
Is the container_manage_cgroup boolean turned on? setsebool -P container_manage_cgroup 1
Sigh, that was it. Sorry for the noise.
