docker的安裝

docker的官網Docker Docs

我才用的linux版本是rocky，使用的是最小安裝

1、安裝yum-utils工具

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

2、安裝yum倉庫

[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、安裝docker引擎

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

4、設置開機啟動，并立即啟動

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

5、測試

[root@bogon ~]# docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world

Digest: sha256:53641cd209a4fecfc68e21a99871ce8c6920b2e7502df0a20671c6fccc73a7c6
Status: Downloaded newer image for hello-world:latestHello from Docker!          ## 出現這行，說明部署成功
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 theexecutable that produces the output you are currently reading.4. The Docker daemon streamed that output to the Docker client, which sent itto your terminal.To try something more ambitious, you can run an Ubuntu container with:$ docker run -it ubuntu bashShare images, automate workflows, and more with a free Docker ID:https://hub.docker.com/For more examples and ideas, visit:https://docs.docker.com/get-started/
