安装 Docker
1、卸载旧版本
sudo yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-selinux \
docker-engine-selinux \
docker-engine
2、配置yum 仓库
$ sudo yum install -y yum-utils
$ sudo yum-config-manager \
--add-repo \
https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
$ sudo sed -i 's/download.docker.com/mirrors.aliyun.com\/docker-ce/g' /etc/yum.repos.d/docker-ce.repo
3、安装docker
sudo yum install -y docker-ce docker-ce-cli containerd.io
4、启动docker
sudo systemctl enable docker
sudo systemctl start docker
systemctl status docker
5、验证docker
docker run --rm hello-world
6、修改docker 镜像地址
默认 docker image 镜像网络访问不了(或者慢),这里配置阿里云的镜像地址
vim /etc/docker/daemon.json
{
"registry-mirrors": ["https://aekshq8n.mirror.aliyuncs.com"]
}
7、卸载docker:
sudo yum remove docker-ce
sudo rm -rf /var/lib/docker
