2.拉取下载镜像- [root@node1 ~]# docker pull nginx
- Using default tag: latest
- latest: Pulling from library/nginx
- b4d181a07f80: Pull complete
- 66b1c490df3f: Pull complete
- d0f91ae9b44c: Pull complete
- baf987068537: Pull complete
- 6bbc76cbebeb: Pull complete

- Digest: sha256:353c20f74d9b6aee359f30e8e4f69c3d7eaea2f610681c4a95849a2fd7c497f9
- Status: Downloaded newer image for nginx:latest
- docker.io/library/nginx:latest
复制代码
3.查察本地镜像- [root@node1 ~]# docker image ls
- REPOSITORY TAG IMAGE ID CREATED SIZE
- nginx latest 4cdc5dd7eaad 2 weeks ago 133MB
复制代码
二、运行镜像
1.安装相干包- [root@node1 ~]# yum install -y libseccomp-devel

2.天生容器- 备注:- d 后台运行容器
- -p 80:80 端口映射 宿主机端口:容器内端口
复制代码
- [root@node1 ~]# docker run -d -p 80:80 nginx
- 2716e3ec14173a31d8c2168ceceefbbfecec0efe6d611bc710df0bc53748ef0c
复制代码
3.查察容器运行状态- [root@node1 ~]# docker ps
- CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
- 2716e3ec1417 nginx "/docker-entrypoint.…" 26 seconds ago Up 24 seconds 0.0.0.0:80->80/tcp, :::80->80/tcp naughty_driscoll
复制代码
三、测试容器内的应用
四、查抄宿主机端口
- [root@node1 ~]# netstat -tunlp |grep 80
- tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 3807/docker-proxy
- tcp6 0 0 :::80 :::* LISTEN 3814/docker-proxy
- tcp6 0 0 :::8081 :::* LISTEN 1092/httpd
复制代码
五、制止容器
- [root@node1 ~]# docker ps
- CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
- 2716e3ec1417 nginx "/docker-entrypoint.…" 6 minutes ago Up 6 minutes 0.0.0.0:80->80/tcp, :::80->80/tcp naughty_driscoll
- [root@node1 ~]# docker stop 2716e3ec1417
- 2716e3ec1417
- [root@node1 ~]# docker start 2716e3ec1417
- 2716e3ec1417
