Centos8 安装 Docker 过程及错误解决

yum install -y yum-utils

yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

yum install docker-ce docker-ce-cli containerd.io

执行安装命令后报错，提示 containerd.io 版本过低

Error:
  Problem: package docker-ce-3:19.03.8-3.el7.x86_64 requires containerd.io >= 1.2.2-3, but none of the providers can be installed
  ...

安装最新的 containerd.io

yum install https://download.docker.com/linux/fedora/30/x86_64/stable/Packages/containerd.io-1.2.13-3.1.fc30.x86_64.rpm

然后安装 docker-ce

yum install docker-ce docker-ce-cli containerd.io

这个时候又报错，docker-ce 与 podman-manpages 冲突

Error: Transaction check error:
  file /usr/share/man/man1/docker-attach.1.gz from install of docker-ce-cli-1:19.03.8-3.el7.x86_64 conflicts with file from package podman-manpages-1.4.2-5.module_el8.1.0+237+63e26edc.noarch
  ...

卸载 podman-manpages

yum remove podman-manpages.noarch

卸载后再次执行安装命令，完成后查看是否安装成功

docker -v
Docker version 19.03.8, build afacb8b

启动 docker

systemctl start docker

设置 docker 开机启动

systemctl enable docker
