1、安装docker

直接使用阿里云上面的安装脚本

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

安装成功后执行docker --help命令被识别则安装成功,常用命令列表

2、常用操作

创建有sudo权限的容器

sudo docker run -itd(后台运行)  --name ubuntu_v1 ubuntu(镜像名称) 
#sudo docker run -itd --privileged --restart=always --name ubuntu_v1 ubuntu /bin/bash 不能赋予privileged权限,和宿主机的权限接近

关闭容器

sudo docker stop ubuntu

开启容器

sudo docker start ubuntu

访问docker容器

sudo docker exec -it ubuntu /bin/bash

把当前修改好的容器打包成镜像:相当于一个tag

docker commit 容器名字 镜像名字

备份镜像:

docker  save -o image.tar imagename

加载备份文件:

docker load -i image.tar

docker中创建用户:

g:gid u:uid
sudo useradd -d /home/wlj -g 999 -u 998 -m -s /bin/bash wlj

添加用户到docker组:

sudo useradd -d /home/test   -g 1001  -m -s /bin/bash test

重启docker服务:会停止所有的容器

systemctl daemon-reload
systemctl restart docker

启动docker service:

systemctl daemon-reload
systemctl start docker.service
systemctl enable docker.service #自动启动
systemctl status docker

限制docker容器大小

修改/etc/systemd/system/docker.service.d/docker.service:
[service]
Type=notify
OPTIONS='--storage-opt overlay2.size=40G'
EnvironmentFile=/etc/sysconfig/docker
