step-2 下载镜像
[root@localhost ~]# docker pull nginx Using default tag: latest latest: Pulling from library/nginx e1acddbe380c: Pull complete e21006f71c6f: Pull complete f3341cc17e58: Pull complete 2a53fa598ee2: Pull complete 12455f71a9b5: Pull complete b86f2ba62d17: Pull complete Digest: sha256:4d4d96ac750af48c6a551d757c1cbfc071692309b491b70b2b8976e102dd3fef Status: Downloaded newer image for nginx:latest docker.io/library/nginx:latest
step-3 运行测试

#-d 后台运行
#--name 给容器命名
#-p 宿主机端口:容器内部端口 #将容器的端口暴露出来，映射到宿主机的端口上 [root@localhost ~]# docker run -d --name nginx01 -p 3344:80 nginx e3711d6853698d2028c961cd2b4b2cfc85386ba32ed3a333f2da82dc0de4e0de [root@localhost ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES e3711d685369 nginx "/docker-entrypoint.…" 11 seconds ago Up 10 seconds 0.0.0.0:3344->80/tcp, :::3344->80/tcp nginx01 e88decf20b06 centos "/bin/bash" 51 minutes ago Up 49 minutes gallant_chaplygin [root@localhost ~]# curl localhost:3344 <!DOCTYPE html> <html> <head> <title>Welcome to nginx!</title> <style> body { width: 35em; margin: 0 auto; font-family: Tahoma, Verdana, Arial, sans-serif; } </style> </head> <body> <h1>Welcome to nginx!</h1> <p>If you see this page, the nginx web server is successfully installed and working.

端口暴露逻辑
step-4 进入容器
