推荐答案

[澄清]:

根据 官方 docker 文档，关于 Centos 操作系统的要求:

Regarding Centos OS requirements as per the official docker docs:

要安装 Docker 引擎 - 社区，你需要一个 CentOS 7 的维护版本.存档版本不受支持或测试.(所以我假设现在不再支持 Centos 6.)

To install Docker Engine - Community, you need a maintained version of CentOS 7. Archived versions aren’t supported or tested. (So I assume Centos 6 is now no longer supported.)

以下配方适用于 Centos 7 和 8

The following recipes are for Centos 7 and 8

Centos 7:

# cat /etc/os-release
NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"
PRETTY_NAME="CentOS Linux 7 (Core)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:7"
HOME_URL="https://www.centos.org/"
BUG_REPORT_URL="https://bugs.centos.org/"

CENTOS_MANTISBT_PROJECT="CentOS-7"
CENTOS_MANTISBT_PROJECT_VERSION="7"
REDHAT_SUPPORT_PRODUCT="centos"
REDHAT_SUPPORT_PRODUCT_VERSION="7"

• 第 1 步:安装所需的软件包.
• Step 1: Install required packages.

$ sudo yum -y update
$ sudo yum install -y yum-utils 
  device-mapper-persistent-data 
  lvm2

• 第 2 步:使用以下命令设置稳定存储库.
• Step 2: Use the following command to set up the stable repository.

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

• 第 3 步:安装最新版本的 Docker CE 和 containerd
• Step 3: Install the latest version of Docker CE and containerd

$ sudo yum install docker-ce docker-ce-cli containerd.io

如果您在此步骤中遇到错误，Package: docker-ce-xxx.centos.x86_64 (docker-ce-stable) Requires: container-selinux >= 2.9

In case you have an error for this step, Package: docker-ce-xxx.centos.x86_64 (docker-ce-stable) Requires: container-selinux >= 2.9

你可以这样做:

$ sudo yum install -y http://mirror.centos.org/centos/7/extras/x86_64/Packages/container-selinux-2.74-1.el7.noarch.rpm

查看问题 Docker CE on RHEL - 需要:容器-selinux >= 2.9

• 第 4 步:启动 Docker.
• Step 4: Start Docker.

$ sudo systemctl start docker

• 第 5 步:通过运行 hello-world 映像验证 Docker CE 是否已正确安装.
• Step 5: Verify that Docker CE is installed correctly by running the hello-world image.

$ sudo docker run hello-world

如果您想以非 root 用户身份使用 Docker，您现在应该考虑将您的用户添加到docker"组，例如:

If you would like to use Docker as a non-root user, you should now consider adding your user to the "docker" group with something like:

$ sudo usermod -aG docker $USER
$ docker run hello-world

应该是这样的.

如果您也想安装 docker-compose，可以关注 其官方文档.

In case you would like to install docker-compose too, you can follow its official docs.

Centos 8:

$ cat /etc/centos-release
CentOS Linux release 8.0.1905 (Core)

$ sudo yum -y update
$ sudo yum install docker
$ sudo docker run hello-world

就是这样.
