type ResourceConfig ¶
ResourceConfig 用于传递资源限制配置的结构体，包含内存限制，CPU 时间片权重，CPU核心数
type Subsystem ¶
type Subsystem interface {
// Name 返回子系统的名称，如cpu、memory
Name() string
// Set 设置某个cgroup在这个子系统的资源限制
Set(cgroupPath string, res *ResourceConfig) error
// Apply 将进程添加到某个cgroup中
Apply(cgroupPath string, pid int, res *ResourceConfig) error
// Remove 移除某个cgroup
Remove(cgroupPath string) error
// CgroupFileName 返回控制子系统资源的cgroup文件名
CgroupFileName() string
}
Subsystem 接口，每个Subsystem可以实现下面的4个接口， 这里将cgroup抽象成了path,原因是cgroup在hierarchy的路径，便是虚拟文件系统中的虚拟路径
