CentOS上安装Docker

Docker centos 官方安装教程：docker for centos

1. 卸载旧的

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

2.设置存储库

安装yum-utils软件包（提供yum-config-manager 实用程序）并设置稳定的存储库。

$ sudo yum install -y yum-utils

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

3.启用测试

$ sudo yum-config-manager --enable docker-ce-nightly

4.开始安装：

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

containerd.io - daemon to interface with the OS API (in this case, LXC - Linux Containers), essentially decouples Docker from the OS, also provides container services for non-Docker container managers
docker-ce - Docker daemon, this is the part that does all the management work, requires the other two on Linux
docker-ce-cli - CLI tools to control the daemon, you can install them on their own if you want to control a remote Docker daemon

这个地方遇到了错误

提示需要 containerd.io并且版本大于1.2.2-3，但是找不到，下面手动安装

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

# yum install https://download.docker.com/linux/fedora/30/x86_64/stable/Packages/containerd.io

安装完成下一步继续安装Docker

 sudo yum install docker-ce docker-ce-cli

其实这3个可以一个个单独安装

yum install docker-ce

OK 安装完成.

如上所示，注意要先安装依赖选项再安装会保险些.

总结：CentOS8 安装Docker六部曲

1.删除旧版本

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

2.安装yum工具并设置存储库

$ sudo yum install -y yum-utils

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

3.安装containerd.io（自动安装找不到路径，这里强制设置安装下载地址）

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

4.安装Docker CE 和Docker ce-cli

 sudo yum install docker-ce docker-ce-cli

5.启动Docker

 sudo systemctl start docker

6.通过运行hello-world 映像来验证是否正确安装了Docker Engine 。

sudo docker run hello-world

补充：

7.开启服务自启动

# systemctl  enable docker.service
Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /usr/lib/systemd/system/docker.service.

其它：

查看docker版本

# docker version
