libcgroups
This is a fork of github.com/uber-go/automaxprocs that exposes the existing functions necessary to get the current process' cgroups, and the cpu quota allocation from that.
Importing the base package will automatically set GOMAXPROCS to match Linux container
CPU quota.
Quick Start
To automatically set GOMAXPROCS:
import _ "github.com/ovesh/automaxprocs"
func main() {
// Your application logic here.
}
To get the current CPU quota
allCGroups, err := cgroups.NewCGroupsForCurrentProcess()
if err != nil {
// handle err
}
quota, defined, err := allCGroups.CPUQuota()
if !defined || err != nil {
// handle err
}
fmt.Println("quota:", quota)

Overview ¶
Package automaxprocs automatically sets GOMAXPROCS to match the Linux container CPU quota, if any.
Example ¶
package main
// Importing automaxprocs automatically adjusts GOMAXPROCS.
import (
"fmt"
"github.com/ovesh/automaxprocs/internal/cgroups"
_ "go.uber.org/automaxprocs"
)
// To render a whole-file example, we need a package-level declaration.
var _ = ""
func main() {}
func getCurrentCPUAllocation() error {
allCGroups, err := cgroups.NewCGroupsForCurrentProcess()
if err != nil {
return err
}
fmt.Printf("all allCGroups: %+v\n", allCGroups)
quota, defined, err := allCGroups.CPUQuota()
if !defined || err != nil {
return err
}
fmt.Println("quota:", quota)
return nil
}
