Functions ¶
func CreateCgroups ¶
func CreateCgroups(m fs.Mounter, root string, enabledCgroups map[int][]string, mountContext string) error
CreateCgroups mounts the v1 cgroup controllers hierarchy in /sys/fs/cgroup under root
func GetCgroupPathByPid ¶
GetCgroupPathByPid returns the cgroup path of the process with the given pid and given controller.
func GetControllerDirs ¶
GetControllerDirs takes a map with the enabled cgroup controllers grouped by hierarchy and returns the directory names as they should be in /sys/fs/cgroup
func GetEnabledCgroups ¶
GetEnabledCgroups returns a map with the enabled cgroup controllers grouped by hierarchy
func GetOwnCgroupPath ¶
GetOwnCgroupPath returns the cgroup path of this process in controller hierarchy
func IsControllerMounted ¶
IsControllerMounted returns whether a controller is mounted by checking that cgroup.procs is accessible
func JoinSubcgroup ¶
JoinSubcgroup makes the calling process join the subcgroup hierarchy on a particular controller
func RemountCgroups ¶ added in v1.21.0
func RemountCgroups(m fs.Mounter, root string, enabledCgroups map[int][]string, subcgroup string, readWrite bool) error
RemountCgroups remounts the v1 cgroup hierarchy under root. It mounts /sys/fs/cgroup/[controller] read-only, but leaves needed knobs in the pod's subcgroup read-write, such that systemd inside stage1 can apply isolators to them. It leaves /sys read-write if the given readWrite parameter is true. When this is done, <stage1>/sys/fs/cgroup/<controller> should be RO, and <stage1>/sys/fs/cgroup/<cotroller>/.../machine-rkt/.../system.slice should be RW
