# cgroups
[![Build Status](https://travis-ci.org/containerd/cgroups.svg?branch=master)](https://travis-ci.org/containerd/cgroups)
[![codecov](https://codecov.io/gh/containerd/cgroups/branch/master/graph/badge.svg)](https://codecov.io/gh/containerd/cgroups)
[![GoDoc](https://godoc.org/github.com/containerd/cgroups?status.svg)](https://godoc.org/github.com/containerd/cgroups)
[![Go Report Card](https://goreportcard.com/badge/github.com/containerd/cgroups)](https://goreportcard.com/report/github.com/containerd/cgroups)
Go package for creating, managing, inspecting, and destroying cgroups.
The resources format for settings on the cgroup uses the OCI runtime-spec found
[here](https://github.com/opencontainers/runtime-spec).
## Examples
### Create a new cgroup
This creates a new cgroup using a static path for all subsystems under `/test`.
* /sys/fs/cgroup/cpu/test
* /sys/fs/cgroup/memory/test
* etc....
It uses a single hierarchy and specifies cpu shares as a resource constraint and
uses the v1 implementation of cgroups.
```go
shares := uint64(100)
control, err := cgroups.New(cgroups.V1, cgroups.StaticPath("/test"), &specs.LinuxResources{
CPU: &specs.CPU{
Shares: &shares,
},
})
defer control.Delete()
```
### Create with systemd slice support
```go
control, err := cgroups.New(cgroups.Systemd, cgroups.Slice("system.slice", "runc-test"), &specs.LinuxResources{
CPU: &specs.CPU{
Shares: &shares,
},
})
```
### Load an existing cgroup
```go
control, err = cgroups.Load(cgroups.V1, cgroups.StaticPath("/test"))
```
### Add a process to the cgroup
```go
if err := control.Add(cgroups.Process{Pid:1234}); err != nil {
}
```
### Update the cgroup
To update the resources applied in the cgroup
```go
shares = uint64(200)
if err := control.Update(&specs.LinuxResources{
CPU: &specs.CPU{
Shares: &shares,
},
}); err != nil {
}
```
### Freeze and Thaw the cgroup
```go
if err := control.Freeze(); err != nil {
}
if err := control.Thaw(); err != nil {
}
```
### List all processes in the cgroup or recursively
```go
processes, err := control.Processes(cgroups.Devices, recursive)
```
### Get Stats on the cgroup
```go
stats, err := control.Stat()
```
By adding `cgroups.IgnoreNotExist` all non-existent files will be ignored, e.g. swap memory stats without swap enabled
```go
stats, err := control.Stat(cgroups.IgnoreNotExist)
```
### Move process across cgroups
This allows you to take processes from one cgroup and move them to another.
```go
err := control.MoveTo(destination)
```
### Create subcgroup
```go
subCgroup, err := control.New("child", resources)
```
