一、docker卸载
yum remove docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-engine
二、docker默认工作门路
/var/lib/docker
三、docker装置
# 1.docker须要的安装包 yum install -y yum-utils
# 2.镜像仓库yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo # 默认是国外的，比较慢 yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo # docker阿里镜像库「快」
# 3.装置docker相干「ce社区版，ee企业版」yum install docker-ce docker-ce-cli containerd.io
# 4.更新软件包索引yum makecache fast
# 5.启动dockersystemctl start docker
# 6.查看docker版本docker version
# 7.装置hello-worlddocker run hello-world
# 8.查看docker镜像docker images
# 9.卸载docker # 9.1.卸载依赖 yum remove docker-ce docker-ce-cli containerd.io # 9.2.删除资源 rm -rf /var/lib/docker rm -rf /var/lib/containerd

# 配置应用sudo mkdir -p /etc/dockersudo tee /etc/docker/daemon.json <<-'EOF'{ "registry-mirrors": ["https://r0gd3ueb.mirror.aliyuncs.com"]}EOFsudo systemctl daemon-reloadsudo systemctl restart docker
四、Docker命令
4.1 docker run 流程
