1. 使用crictl 查看容器ID

crictl ps

2. 查看Cgroup位置

crictl inspect 容器ID

3. 到容器Cgroup的目录下

使用上个命令就能找到CgroupPath

4 . 到cgroup目录下

正确目录是 :
/sys/fs/cgroup/memory/kubepods.slice/kubepods-burstable.slice/kubepods-burstable-podf68e1877_4a10_423e_a0f4_9ac64be78637.slice/cri-containerd-b639921a4406145ca0c7adea96b231e533cb8d17f02182758d8fc4b8ef9b24df.scope
其中: /sys/fs/cgroup/memory/kubepods.slice/kubepods-burstable.slice/ 是固定的然后根据上个命令查看的位置移动到该目录

修改值

使用echo 将值放入上个地址目录中的

echo 1073741824 > /sys/fs/cgroup/memory/kubepods.slice/kubepods-burstable.slice/kubepods-burstable-podf68e1877_4a10_423e_a0f4_9ac64be78637.slice/cri-containerd-b639921a4406145ca0c7adea96b231e533cb8d17f02182758d8fc4b8ef9b24df.scope/memory.limit_in_bytes
