CentOS7使用Yum安装最新版Docker

1、先移除旧版本

sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

2、安装最新版

sudo yum install -y yum-utils
sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo
 
 sudo yum install docker-ce docker-ce-cli containerd.io

安装小插曲，阿里云出现奇怪错误

Error: moby-containerd conflicts with containerd.io-1.4.4-3.1.el7.x86_64
Error: moby-runc conflicts with containerd.io-1.4.4-3.1.el7.x86_64
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

按照说明，增加参数安装OK。

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

3、安装指定版本

yum list docker-ce --showduplicates | sort -r

# 以下是你看到的，选个版本吧
docker-ce.x86_64            3:18.09.5-3.el7                     docker-ce-stable
docker-ce.x86_64            3:18.09.4-3.el7                     docker-ce-stable
docker-ce.x86_64            3:18.09.3-3.el7                     docker-ce-stable
docker-ce.x86_64            3:18.09.2-3.el7                     docker-ce-stable
docker-ce.x86_64            3:18.09.1-3.el7                     docker-ce-stable
docker-ce.x86_64            3:18.09.0-3.el7                     docker-ce-stable
docker-ce.x86_64            18.06.3.ce-3.el7                    docker-ce-stable
...

# 安装指定版本,例如：docker-ce-18.09.1，自行替换 VERSION_STRING
sudo yum install docker-ce-<VERSION_STRING> docker-ce-cli-<VERSION_STRING> containerd.io

4、开启服务

sudo systemctl start docker
sudo systemctl enable docker

5、移除docker

sudo yum remove docker-ce docker-ce-cli containerd.io

# 删除下载的镜像和容器
sudo rm -rf /var/lib/docker
sudo rm -rf /var/lib/containerd
