dockerfile案例
一、构建nginx镜像
1、确保有centos镜像（基于centos镜像构建nginx镜像）
[root@stw ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
stwhttpd v1 765a412de517 8 days ago 535MB
stwbuntu v1 73ae18a02dfa 8 days ago 146MB
centosstw v1 8afcbcc87f39 8 days ago 204MB
galaxy v1 358cb5259f15 8 days ago 204MB
nginx latest 41f689c20910 8 weeks ago 192MB
httpd latest 65005131d37e 2 months ago 117MB
centos 7 eeb6ee3f44bd 4 years ago 204MB
2、vim Dockerfile
[root@stw ~]# vim Dockerfile
[root@stw ~]# cat Dockerfile
FROM centos:7
RUN rm -rf /etc/yum.repos.d/*
ADD Centos-7.repo /etc/yum.repos.d/
ADD epel-7.repo /etc/yum.repos.d/
RUN yum -y install nginx
EXPOSE 80
CMD [ "/usr/sbin/nginx","-g","daemon off;" ]
3、构建镜像（build）
[root@stw ~]# docker build -t nginx:v1 .
[+] Building 55.4s (10/10) FINISHED docker:default
=> [internal] load build definition from Dockerfile 0.0s
=> => transferring dockerfile: 233B
......
......
[root@stw ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
nginx v1 a5e908e18c94 8 seconds ago 536MB
stwhttpd v1 765a412de517 8 days ago 535MB
stwbuntu v1 73ae18a02dfa 8 days ago 146MB
centosstw v1 8afcbcc87f39 8 days ago 204MB
galaxy v1 358cb5259f15 8 days ago 204MB
nginx latest 41f689c20910 8 weeks ago 192MB
httpd latest 65005131d37e 2 months ago 117MB
centos 7 eeb6ee3f44bd 4 years ago 204MB
[root@stw ~]# docker ps -a

[root@stw ~]# docker container prune //清空掉所有已停止的容器

[root@stw ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
4、将镜像运行成容器
[root@stw ~]# docker run -itd --name nginx -p 80:80 nginx:v1
bd3781b0038f01e52f2505687ffb4ce172a9983aa0aa1f282dd4159702e0ccac
[root@stw ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
bd3781b0038f nginx:v1 "/usr/sbin/nginx -g …" 6 seconds ago Up 6 seconds 0.0.0.0:80->80/tcp, :::80->80/tcp nginx
5、对nginx进行访问（网页有问题，此时是基于镜像构建的nginx镜像）
6、进入容器修改网页
[root@stw ~]# docker exec -it nginx /bin/bash
[root@bd3781b0038f /]# cd /usr/share/nginx/
[root@bd3781b0038f nginx]# ls
html modules
[root@bd3781b0038f nginx]# cd html
[root@bd3781b0038f html]# ls
404.html 50x.html en-US icons img index.html nginx-logo.png poweredby.png
[root@bd3781b0038f html]# rm -rf index.html
[root@bd3781b0038f html]# echo 123 > index.html
7、再次测试
8、将修改网页写入Dockerfile
[root@stw ~]# vim Dockerfile
[root@stw ~]# cat Dockerfile
FROM centos:7
RUN rm -rf /etc/yum.repos.d/*
ADD Centos-7.repo /etc/yum.repos.d/
ADD epel-7.repo /etc/yum.repos.d/
RUN yum -y install nginx
RUN rm -rf /usr/share/nginx/html/index.html && echo 12345 > /usr/share/nginx/html/index.html
EXPOSE 80
CMD [ "/usr/sbin/nginx","-g","daemon off;" ]
[root@stw ~]# docker build -t nginx:v2 .
[+] Building 0.7s (11/11) FINISHED docker:default
=> [internal] load build definition from Dockerfile 0.0s
=> => transferring dockerfile: 326B
......
......
[root@stw ~]# docker run -itd --name nginx2 -P nginx:v2
44f4ea6fb6f62e389372e480edf8971eeba46d91bb652535c8bf45224e5fc2fa
[root@stw ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
44f4ea6fb6f6 nginx:v2 "/usr/sbin/nginx -g …" 6 seconds ago Up 5 seconds 0.0.0.0:32768->80/tcp, :::32768->80/tcp nginx2
bd3781b0038f nginx:v1 "/usr/sbin/nginx -g …" 10 minutes ago Up 10 minutes 0.0.0.0:80->80/tcp, :::80->80/tcp nginx
测试访问
二、扫雷游戏案例（本地下载）
1、将扫雷的压缩包文件上传到本地
[root@stw ~]# rz -E
rz waiting to receive.
[root@stw ~]# ls
anaconda-ks.cfg Documents Music Templates
Centos-7.repo Downloads Pictures ubuntu-12.04-x86-minimal.tar.gz
Desktop epel-7.repo Public Videos
Dockerfile initial-setup-ks.cfg saolei.zip
2、vim Dockerfile
[root@stw ~]# vim Dockerfile
[root@stw ~]# cat Dockerfile
FROM centos:7
RUN rm -rf /etc/yum.repos.d/*
ADD Centos-7.repo /etc/yum.repos.d/
ADD epel-7.repo /etc/yum.repos.d/
RUN yum -y install tomcat unzip
WORKDIR /var/lib/tomcat/webapps/
ADD saolei.zip .
RUN unzip saolei.zip && mv saolei ROOT
ADD init.sh /init.sh
EXPOSE 8080
CMD ["/bin/bash","/init.sh"]
3、vim init.sh
[root@stw ~]# vim init.sh
[root@stw ~]# cat init.sh
#!/bin/bash
/usr/libexec/tomcat/server start
4、构建镜像（build）
[root@stw ~]# docker build -t saolei:v1 .
[+] Building 85.8s (14/14) FINISHED docker:default
=> [internal] load build definition from Dockerfile 0.0s
=> => transferring dockerfile: 336B

httpd latest 65005131d37e 2 months ago 117MB
centos 7 eeb6ee3f44bd 4 years ago 204MB
5、将镜像运行成容器
[root@stw ~]# docker run -itd --name saolei -P saolei:v1
2ec2805506dadf592e08eb613b26f3528987fb13b7a23d270316476100fdd7ed
[root@stw ~]# docker ps

[root@stw ~]# docker exec -it saolei /bin/bash
[root@2ec2805506da webapps]# cd ROOT
[root@2ec2805506da ROOT]# ls
imgs saolei.jsp
6、测试访问（ 192.168.100.10:32769/saolei.jsp )
网页下载（配置apache）
1、确保80端口没有被占用
[root@stw ~]# ss -anlt

2、下载httpd服务
在docker主机中部署apache服务，并将saolei.zip放置到该站点中，使其通过http://docker主机ip/saolei.zip可以下载
（1）yum -y install httpd
[root@stw ~]# yum -y install httpd
（2）将Centos-7.repo和epel-7.repo文件上传至/root目录
[root@stw ~]# cd /root
[root@stw ~]# ls
anaconda-ks.cfg epel-7.repo saolei.zip
Centos-7.repo initial-setup-ks.cfg Templates
Desktop init.sh ubuntu-12.04-x86-minimal.tar.gz
Dockerfile Music Videos
Documents Pictures
Downloads Public
（3）将saolei.zip包放置/var/www/html目录下
[root@stw ~]# cd /var/www/html
[root@stw html]# ls
[root@stw html]# rz -E
rz waiting to receive.
[root@stw html]# ls
saolei.zip
[root@stw html]# touch index.html
[root@stw html]# ls
index.html saolei.zip
（4）重启apache服务并设置下次启动生效
[root@stw html]# systemctl restart httpd
[root@stw html]# systemctl enable httpd
Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.
[root@stw html]# ss -anlt

LISTEN 0 128 :::32769 :::*
LISTEN 0 128 :::32770 :::*
3、vim Dockerfile并且vim init.sh
[root@stw ~]# vim Dockerfile
[root@stw ~]# cat Dockerfile
FROM centos:7
RUN rm -rf /etc/yum.repos.d/*
ADD Centos-7.repo /etc/yum.repos.d/
ADD epel-7.repo /etc/yum.repos.d/
RUN yum -y install tomcat unzip curl
WORKDIR /var/lib/tomcat/webapps/
RUN curl -O http://192.168.100.10/saolei.zip && \
unzip saolei.zip && \
mv saolei ROOT
ADD init.sh /init.sh
EXPOSE 8080
CMD ["/bin/bash","/init.sh"]
[root@stw ~]# vim init.sh
[root@stw ~]# cat init.sh
