服务器版本: Red Hat Enterprise Linux Server release 7.5
在安装Docker CE的时候提示 WARNING: rhel is now only supported by Docker EE
Check https://store.docker.com for information on Docker EE
解决办法如下:
- Install yum-utils. 执行
yum install -y yum-utils - Install epel-release. 执行
wget http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm和rpm -ivh epel-release-latest-7.noarch.rpm - Add Docker CE to yum repos.
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo - 安装container-selinux,因为docker-ce依赖于container-selinux,
yum install -y http://mirror.centos.org/centos/7/extras/x86_64/Packages/container-selinux-2.33-1.git86f33cd.el7.noarch.rpm, 如果不行尝试执行yum -y --enablerepo=rhui-REGION-rhel-server-extras install container-selinux - 安装Docker CE
yum install -y docker-ce - 查看是否安装成功
docker --version - 重启Docker服务并加入开机启动
systemctl restart docker和systemctl enable docker - 安装nginx容器测试下
docker run --name webserver -d -p 9090:80 nginx
安装完成后，需要把当前用户添加到用户组才能不以root身份运行
sudo usermod -aG docker ec2-user
