Centos7安装docker(报错:container-selinux >= 2:2.74)

step 1: 安装必要的一些系统工具

yum install -y yum-utils device-mapper-persistent-data lvm2

Step 2: 添加软件源信息

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

yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
Centos7安装docker(报错:container-selinux >= 2:2.74)

Step 3: 安装 Docker-CE

yum -y install docker-ce
Centos7安装docker(报错:container-selinux >= 2:2.74)

Step 4: 开启Docker服务

systemctl restart docker
systemctl enable docker

安装docker时报container-selinux >= 2.9错误

如果安装docker时出现了以下错误
Error: Package: containerd.io-1.2.13-3.2.el7.x86_64 (docker-ce-stable)
Requires: container-selinux >= 2:2.74
Error: Package: 3:docker-ce-19.03.12-3.el7.x86_64 (docker-ce-stable)
Requires: container-selinux >= 2:2.74
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

这个报错是container-selinux版本低或者是没安装的原因
yum 安装container-selinux 一般的yum源又找不到这个包
需要安装epel源 才能yum安装container-selinux
然后在安装docker-ce就可以了。

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum install epel-release
yum makecache
yum install container-selinux
