CentOS 8.1 安装docker-ce

添加docker-ce的yum源

实际上，添加的这个yum源仍然是el7的

yum install -y yum-utils

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

安装依赖包：

yum install https://download.docker.com/linux/fedora/30/x86_64/stable/Packages/containerd.io-1.2.6-3.3.fc30.x86_64.rpm
Install Docker Engine

安装docker-ce

yum install docker-ce  -y

安装docker-ce报错:

 file /usr/share/man/man1/docker-volume.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

解决方法：

yum  remove podman-manpages -y

然后重新安装docker-ce即可

docker 国内源

mkdir -p /etc/docker
tee /etc/docker/daemon.json <<EOF
