OpenEuler安装最新版Docker CE

为什么选择OpenEuler

1. 之前CentOS忽然停止维护

2. OpenEuler也是Redhat系的衍生版本

3. 正巧想要一个虚拟机专门来运行docker

为什么要特意写这篇文章

1. OpenEuler不能直接安装最新的Docker CE版本，OpenEuler默认能够安装的版本为18.09.0

2. 我在使用该版本的过程中发现该版本重启之后会自动重置docker的网络配置，以及docker容器之间，即使在同网段仍然无法互通等情况，故弃坑（实在是不想研究）...

配置软件源

OpenEuler配置CentOS软件源

1. 新增CentOS软件源

   wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.huaweicloud.com/repository/conf/CentOS-7-reg.repo

2. 修改CentOS-7-reg.repo

   sed -i 's/$releasever/7/g' /etc/yum.repos.d/CentOS-Base.repo

3. 查看以下修改效果

   cat /etc/yum.repos.d/CentOS-Base.repo

   应该所有的$releasever都变成7才对

   # CentOS-Base.repo
   #
   # The mirror system uses the connecting IP address of the client and the
   # update status of each mirror to pick mirrors that are updated to and
   # geographically close to the client.  You should use this for CentOS updates
   # unless you are manually picking other mirrors.
   #
   # If the mirrorlist= does not work for you, as a fall back you can try the
   # remarked out baseurl= line instead.
   #
   #

OpenEuler配置Docker CE软件源

1. 添加Docker-CE软件源

   wget -O /etc/yum.repos.d/docker-ce.repo https://repo.huaweicloud.com/docker-ce/linux/centos/docker-ce.repo

2. 修改docker-ce.repo

   sed -i 's/$releasever/7/g' /etc/yum.repos.d/docker-ce.repo

3. 查看以下修改效果

   cat /etc/yum.repos.d/docker-ce.repo

   应该所有的$releasever都变成7才对

   [docker-ce-stable]
   name=Docker CE Stable - $basearch

刷新软件源

yum clean all && yum makecache

允许IPv4转发

Docker运行需要允许网络转发

nano /etc/sysctl.conf

将其中的net.ipv4.ip_forward修改为1

net.ipv4.ip_forward=1

使其生效

sysctl -p

OpenEuler安装Docker CE

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

   sudo yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin

3. 启动

   sudo systemctl start docker

4. 开机运行

   sudo systemctl enable docker

测试

sudo docker run hello-world

Docker免Root运行

usermod -aG docker ${USER}

移除软件源

保持系统干净，因为非官方指定的软件源，故还是选择避免污染

Docker

mv /etc/yum.repos.d/docker-ce.repo /etc/yum.repos.d/docker-ce.repo.bak

CentOS

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak

刷新

yum clean all && yum makecache
