Docker：构建nginx镜像，扫雷，可道云平台

用dockerfile在centos7的基础上构建nginx的镜像

[root@docker ~]# vim 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;"]

[root@docker ~]# docker build -t nginx:v1 .
[root@docker ~]# docker run -itd --name nginx -P nginx:v1
85a277b8b628d7a5f71879318eef57339244bef5dffb3cc441062414112ceba3
[root@docker ~]# docker ps
CONTAINER ID   IMAGE      COMMAND                  CREATED          STATUS          PORTS                                     NAMES
85a277b8b628   nginx:v1   "/usr/sbin/nginx -g …"   16 seconds ago   Up 15 seconds   0.0.0.0:32768->80/tcp, :::32768->80/tcp   nginx

访问网页测试

发现没有网页。我们进到nginx里查看

[root@docker ~]# docker exec -it nginx /bin/bash

发现网页故障，我们重新覆盖一下网页

[root@85a277b8b628 html]# rm -rf index.html 
[root@85a277b8b628 html]# echo testnginx > index.html

再次测试，发现能够成功访问

扫雷案例

我们可以通过网页下载扫雷，也可以用本地的扫雷包来完成

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"]

创建init.sh的脚本

[root@docker ~]# vim init.sh
#!/bin/bash
/usr/libexec/tomcat/server start

构建saolei的镜像

[root@docker ~]# docker build -t saolei:v1 .

运行saolei容器

[root@docker ~]# docker run -itd --name saolei -P saolei:v1

[root@docker ~]# docker ps -a
CONTAINER ID   IMAGE       COMMAND                  CREATED          STATUS          PORTS                                         NAMES
4c88be42ec37   saolei:v1   "/bin/bash /init.sh"     26 seconds ago   Up 25 seconds   0.0.0.0:32769->8080/tcp, :::32769->8080/tcp   saolei
85a277b8b628   nginx:v1    "/usr/sbin/nginx -g …"   24 minutes ago   Up 24 minutes   0.0.0.0:32768->80/tcp, :::32768->80/tcp       nginx

构建镜像

[root@docker kod]# docker build -t kod:v3 .

运行

[root@docker kod]# docker run -itd --name kod -P kod:v3

[root@docker kod]# docker ps
