docker - 为什么docker run `--oom-kill-disable` 无效，而`echo 1 > memory.oom_control` 在我自己的系统中有效！

问题描述

当我为 docker run --oom-kill-disable 运行一个容器时，它是无效的；但是当我“echo 1 > memory.oom_control”时，它是有效的。

docker version:
Client:
 Version:   17.12.0-ce
 API version:   1.35
 Go version:    go1.9.2
 Git commit:    c97c6d6
 Built: Wed Dec 27 20:05:38 2017
 OS/Arch:   linux/amd64

Server:
 Engine:
  Version:  17.12.0-ce
  API version:  1.35 (minimum version 1.12)
  Go version:   go1.9.2
  Git commit:   c97c6d6
  Built:    Wed Dec 27 20:12:29 2017
  OS/Arch:  linux/amd64
  Experimental: false

1.sudo docker run -it --memory=100M --oom-kill-disable MyselfImage /bin/bash
2.stress --vm 1 --vm-bytes 200M #stress process is killed
stress: info: [42] dispatching hogs: 0 cpu, 0 io, 1 vm, 0 hdd
stress: FAIL: [42] (415) <-- worker 43 got signal 9
stress: WARN: [42] (417) now reaping child worker processes
stress: FAIL: [42] (451) failed run completed in 1s
3.echo 1 > /sys/fs/cgroup/memory/docker/XXX/memory.oom_control
4.stress --vm 1 --vm-bytes 200M #stress process is not killed
stress: info: [42] dispatching hogs: 0 cpu, 0 io, 1 vm, 0 hdd
...

为什么 memory.oom_control 文件不被--oom-kill-disable参数更改。

解决方案

当我尝试 docker 19.03.7 时，它可以工作！所以，这个问题是我的 docker(17.12.0-ce) 中的一个错误
