Docker does not know about our named cpuacct,cpu,cpuset cgroup hierarchy with multiple subsystems in it. So to use them with docker in integration-cli test TestRunWithCpuset inside docker container we need to add symlinks to them in hack/dind script. Example: old version of parser will do: cat /proc/1/cgroup 11:cpu,cpuacct,name=my_cpu_cpuacct:/ ... and create and mount this hierarchy to directory /cgroup/cpu,cpuacct,name=my_cpu_cpuacct/ so docker cannot find it because it has strange name in new parser directory will be same as on host /cgroup/my_cpu_cpuacct and have symlinks for docker to find it /cgroup/cpu -> /cgroup/my_cpu_cpuacct /cgroup/cpuacct -> /cgroup/my_cpu_cpuacct in other case if where is no name cat /proc/1/cgroup 11:cpu,cpuacct:/ ... mount will be same for both parsers /cgroup/cpu,cpuacct and new one will also create symlinks /cgroup/cpu -> /cgroup/cpu,cpuacct /cgroup/cpuacct -> /cgroup/cpu,cpuacct Signed-off-by: Pavel Tikhomirov <ptikhomirov@parallels.com> Upstream-commit: d322cd5dcb0ad480c974f4cc58d9d01c3d2801a7 Component: engine
