docker.md

修改默认存储位置：

vim /etc/docker/daemon.json

{
  "graph": "/docker"
}

非root用户使用docker命令

https://docs.docker.com/engine/installation/linux/linux-postinstall/#manage-docker-as-a-non-root-user

sudo groupadd docker
udo usermod -aG docker $USER

通过ssh直接连接docker container

https://docs.docker.com/engine/examples/running_ssh_service/

对于centos,需要在修改sshd_config之前，先生成，即添加 RUN /usr/bin/ssh-keygen -A

限制一个主机上所有docker容器的CPU使用 vim /etc/systemd/system/docker_limit.slice [Unit] Description=Slice that limits docker resources Before=slices.target

[Slice] CPUAccounting=true CPUQuota=140% #Memory Management #MemoryAccounting=true #MemoryLimit=2G

systemctl start docker_limit.slice systemctl daemon-reload systemctl start docker_limit.slice
