构建镜像

通过Dockerfile创建一个ubuntu带nginx的镜像

root@ubuntu:~# mkdir -p /dockerfile/df_test2root@ubuntu:~# cd /dockerfile/df_test2/root@ubuntu:/dockerfile/df_test2# vim Dockerfileroot@ubuntu:/dockerfile/df_test2# cat Dockerfile # 设置基本的镜像，后续命令都以这个镜像为基础  FROM ubuntu# 作者信息  MAINTAINER  shangwu  # RUN命令会在上面指定的镜像里执行任何命令  RUN apt-get updateRUN apt-get install -y nginx#暴露ssh端口EXPOSE  80  root@ubuntu:/dockerfile/df_test2# docker images REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZEubuntu-nginx        v1                  8377a82bd88d        6 minutes ago       232.8 MBubuntu              latest              dc8dd8718e57        10 days ago         119.2 MB

执行Dockerfile

root@ubuntu:/dockerfile/df_test2# docker build -t='ubuntu-nginx-df_test2' .root@ubuntu:/dockerfile/df_test2# docker imagesREPOSITORY              TAG                 IMAGE ID            CREATED             VIRTUAL SIZEubuntu-nginx-df_test2   latest              266559c6bc7f        2 minutes ago       214.3 MBubuntu-nginx            v1                  8377a82bd88d        13 minutes ago      232.8 MBubuntu                  latest              dc8dd8718e57        10 days ago         119.2 MBroot@ubuntu:/dockerfile/df_test2#

通过刚刚创建的进行启动一个容器=nginx-web3

root@ubuntu:/dockerfile/df_test2# docker run -d --name=nginx-web3 -p 80 ubuntu-nginx-df_test2 nginx -g "daemon off;"ffd39288dbdcd6af18beba89278e80e88d464e9e34388c4d61f181dfe3081d1croot@ubuntu:/dockerfile/df_test2# docker psCONTAINER ID        IMAGE                          COMMAND                CREATED             STATUS              PORTS                   NAMESffd39288dbdc        ubuntu-nginx-df_test2:latest   "nginx -g 'daemon of   7 seconds ago       Up 6 seconds        0.0.0.0:32771->80/tcp   nginx-web3          892ba90fd7f0        ubuntu-nginx:v1                "nginx -g 'daemon of   12 minutes ago      Up 12 minutes       0.0.0.0:32770->80/tcp   nginx-web2          fbfacadb6dfe        ubuntu-nginx:v1                "nginx -g 'daemon of   13 minutes ago      Up 13 minutes       80/tcp                  nginx-web1          666dc69dc786        ubuntu:latest                  "/bin/bash"            8 hours ago         Up About an hour    0.0.0.0:32769->80/tcp   web                 root@ubuntu:/dockerfile/df_test2# curl http://127.0.0.1:32771<!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 andworking.
