重装 Docker

安装 docker-ce-18.06.0.ce

[root@Docker ]# yum remove docker  docker-common docker-selinux docker-engine -y
[root@Docker ]# yum install -y docker-ce-18.06.0.ce

可能会遇到的报错

 file /usr/share/zsh/vendor-completions/_docker from install of docker-ce-18.06.0.ce-3.el7.x86_64 conflicts with file from package docker-ce-cli-1:19.03.8-3.el7.x86_64

Error Summary

解决方法

卸载 docker-ce-cli-1:19.03.8-3.el7.x86_64 -y

[root@Docker ]# yum erase docker-ce-cli-1:19.03.8-3.el7.x86_64 -y

再次安装 docker-ce-18.06.0.ce

[root@Docker ]# yum install -y docker-ce-18.06.0.ce
[root@Docker ]# systemctl start docker
[root@Docker ]# systemctl enable docker
