Rocky Linux 安装 Docker
前置
安装之前卸载删除之前的Docker
sudo yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-engine \
podman \
runc
rm -rf /var/lib/docker/
安装
- 设置存储库
sudo yum install -y yum-utils
sudo dnf config-manager --add-repo https://download.docker.com/linux/fedora/docker-ce.repo
!如果按照官方教程使用yum安装了, 使用sed命令删除
sed -i -e 's/baseurl=https:\/\/download\.docker\.com\/linux\/\(fedora\|rhel\)\/$releasever/baseurl\=https:\/\/download.docker.com\/linux\/centos\/$releasever/g' /etc/yum.repos.d/docker-ce.repo
- 安装Docker
sudo dnf install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
- 启动Docker
sudo systemctl start docker
- 通过运行
hello-world映像来验证 Docker 引擎安装是否成功。
sudo docker run hello-world
优化设置
- 自启
sudo systemctl enable docker
- 添加源
vi /etc/docker/daemon.json
添加任意一个国内源
{
