3、启动docker
[root@localhost ~]# docker -v && systemctl restart docker && systemctl enable docker
Docker version 27.3.1, build ce12230
Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /usr/lib/systemd/system/docker.service.
4、运行/拉取镜像测试
[root@localhost ~]# docker run hello-world
Unable to find image 'hello-world:latest' locally
latest: Pulling from library/hello-world
c1ec31eb5944: Pull complete
Digest: sha256:305243c734571da2d100c8c8b3c3167a098cab6049c9a5b066b6021a60fcb966
Status: Downloaded newer image for hello-world:latest
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
-
The Docker client contacted the Docker daemon.
-
The Docker daemon pulled the "hello-world" image from the Docker Hub.
(amd64)
- The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
- 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
