Functions ¶
Types ¶
type Cgroup ¶
type Cgroup struct {
Name string `json:"name"`
Parents map[string]string `json:"parents"`
Own map[string]bool `json:"own"`
}
Cgroup represents a group inside all controllers. For example:
Name='/foo/bar' maps to /sys/fs/cgroup/<controller>/foo/bar on all controllers.
If Name is relative, it uses the parent cgroup path to determine the location. For example:
Name='foo/bar' and Parent[ctrl]="/user.slice", then it will map to /sys/fs/cgroup/<ctrl>/user.slice/foo/bar
func NewFromPid ¶
NewFromPid loads cgroup for the given process.
func NewFromSpec ¶
NewFromSpec creates a new Cgroup instance if the spec includes a cgroup path. Returns nil otherwise. Cgroup paths are loaded based on the current process.
func (*Cgroup) Install ¶
func (c *Cgroup) Install(res *specs.LinuxResources) error
Install creates and configures cgroups according to 'res'. If cgroup path already exists, it means that the caller has already provided a pre-configured cgroups, and 'res' is ignored.
func (*Cgroup) Join ¶
Join adds the current process to the all controllers. Returns function that restores cgroup to the original state.
func (*Cgroup) MemoryLimit ¶
MemoryLimit returns the memory limit.
