Docker.安装.yum.Centos-8版本

环境

Centos.8
阿里云

失败案例

1.进入阿里云镜像地址，执行下方命令

yum install -y https://mirrors.aliyun.com/docker-ce/linux/centos/7/x86_64/edge/Packages/containerd.io-1.2.13-3.1.el7.x86_64.rpm

---

2.再执行安装命令

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

---

后面安装的过程中直接点y就行，这也是我在网上收集看到的，执行不太有效...

成功案例

yum找不到安装包 => Error: No matching Packages to list

[root@iZ2zeca7jric8sx4f3n7spZ ~]# yum list docker-ce --showduplicates |sort -r
Error: No matching Packages to list

一波操作之后

sudo yum update
sudo yum install -y yum-utils
sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
sudo yum makecache

可以找到docker安装包了

[root@iZ2zeca7jric8sx4f3n7spZ ~]# yum list docker-ce --showduplicates | sort -r

安装docker.{3:20.10.1-3.el7}版本

安装container

//安装后发现,containerd版本太低还是不行...
"requires containerd.io >= 1.4.1",但是我安装的是"containerd.io-1.3.7-3.1.el8.x86_64.rpm"

安装docker其它版本

#安装

[root@iZ2zeca7jric8sx4f3n7spZ ~]# yum -y install docker-ce-19.03.9-3.el7
