前言

openEuler 22.03 LTS-SP4 自带旧版 docker-engine，会和 docker-ce 冲突，安装前需要先卸载旧版。

⚠️ 欧拉自带旧版 docker-engine，会和 docker-ce 冲突，先卸载。

0. 卸载旧版 docker-engine

dnf remove -y docker docker-client docker-client-latest docker-common docker-latest docker-latest-logrotate docker-logrotate docker-engine

1. 创建 docker-ce 华为源

cat > /etc/yum.repos.d/docker-ce.repo <<'EOF'
[docker-ce-stable]
name=Docker CE Stable - $basearch
baseurl=https://repo.huaweicloud.com/docker-ce/linux/centos/8/$basearch/stable
enabled=1
gpgcheck=1
gpgkey=https://repo.huaweicloud.com/docker-ce/linux/centos/gpg
EOF

2. 清理缓存、安装

dnf clean all
dnf makecache
dnf install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

3. 启动 & 开机自启

systemctl start docker
systemctl enable docker

4. 配置国内镜像加速

mkdir -p /etc/docker
tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": [
    "https://docker.mirrors.ustc.edu.cn",
    "https://hub-mirror.c.163.com"
  ]
}
EOF
systemctl daemon-reload
systemctl restart docker

5. 验证

docker -v
docker run hello-world
