docker的安装

docker的官网Docker Docs

我才用的linux版本是rocky，使用的是最小安装

1、安装yum-utils工具

[root@bogon yum.repos.d]# yum install -y yum-utils

2、安装yum仓库

[root@bogon ~]# sudo dnf config-manager --add-repo https://download.docker.com/linux/rhel/docker-ce.repo
Adding repo from: https://download.docker.com/linux/rhel/docker-ce.repo
[root@bogon ~]# yum repolist
repo id                                           repo name
appstream                                         Rocky Linux 9 - AppStream
baseos                                            Rocky Linux 9 - BaseOS
docker-ce-stable                                  Docker CE Stable - x86_64
extras                                            Rocky Linux 9 - Extras

3、安装docker引擎

[root@bogon ~]# yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

4、设置开机启动，并立即启动

[root@bogon ~]# systemctl enable docker --now
Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /usr/lib/systemd/system/docker.service.

5、测试

[root@bogon ~]# docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
c1ec31eb5944: Pull complete 
Digest: sha256:53641cd209a4fecfc68e21a99871ce8c6920b2e7502df0a20671c6fccc73a7c6
Status: Downloaded newer image for hello-world:latest

Hello from Docker!          ## 出现这行，说明部署成功
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash
