如果之前安装过docker需要删除之前的。

for pkg in docker.io docker-doc docker-compose docker-compose-v2 podman-docker containerd runc; do sudo yum -y remove $pkg; done

安装yum-utils工具：

dnf -y install yum-utils dnf-plugins-core

设置存储库：添加国内阿里docker镜像源

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

docker官网存储库

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

docker由于在国外以及国家方面的一些情况导致并没有开放docker官网的。建议使用阿里云。

安装docker软件包

sudo dnf -y install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

添加docker镜像

cat >/etc/docker/daemon.json<< jingyu
{"registry-mirrors": ["https://docker.1ms.run","https://doublezonline.cloud","https://dislabaiot.xyz","https://docker.fxxk.dedyn.io","https://dockerpull.org","https://docker.unsee.tech","https://hub.rat.dev","https://docker.1panel.live","https://docker.nastool.de","https://docker.zhai.cm","https://docker.5z5f.com","https://a.ussh.net","https://docker.udayun.com","https://hub.geekery.cn"]
}

启动docker engine

sudo systemctl enable --now docker

通过运行映像来验证安装是否成功：hello-world

sudo docker run hello-world
