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
