89a4d4b071 kubelet: modify the function of getCgroupSubsystemsV2 to use libcontainer API 2021-06-24 16:58:05 +09:00
b10s
de60340e51 Improve the getCgroupSubsystemsV1() which uses random record per subsystem 
returned by libcontainercgroups.GetCgroupMounts().

Example array from GetCgroupMounts():
```
[
        {
                Mountpoint: "/sys/fs/cgroup/systemd",
                Root: "/",
                Subsystems: []string len: 1, cap: 1, ["systemd"],},
        {
                Mountpoint: "/sys/fs/cgroup/cpu,cpuacct",
                Root: "/",
                Subsystems: []string len: 2, cap: 2, ["cpu","cpuacct"],},
        {
                Mountpoint: "/sys/fs/cgroup/systemd/some/path",
                Root: "/some/path",
                Subsystems: []string len: 1, cap: 1, ["systemd"],},
]
```
becames a map:
```
[
        "memory": "/sys/fs/cgroup/memory/kubepods",
        "systemd": "/sys/fs/cgroup/systemd/some/path",
]
```
which seems to be wrong.

Using shortest path of mountpoint per subsystem would be more reliable.

kubelet: clamp cpu shares to max allowed 
clamp the max cpu.shares to the maximum value allowed by the kernel.

It is not an issue when using cgroupfs, as the kernel will
anyway make sure the value is not out of range and automatically clamp
it, systemd has an additional check that prevents the cgroup creation.

Closes: https://github.com/kubernetes/kubernetes/issues/92855

kubelet: add initial support for cgroupv2 
do a conversion from the cgroups v1 limits to cgroups v2.

e.g. cpu.shares on cgroups v1 has a range of [2-262144] while the
equivalent on cgroups v2 is cpu.weight that uses a range [1-10000].

This PR adds the pod-level metrics for CPU and memory stats. cAdvisor
can get all pod cgroup information so we can add this pod-level CPU and
memory stats information from the corresponding pod cgroup

Need to count in init-container when calculating a pod's cpu limits.
Otherwise, may cause pod start failure due to "invalid argument"
error while trying to write "cpu.cfs_quota_us" file.
