dockerfile构建nginx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 container prune
[root@docker ~] docker run -itd --name nginx -p 88:80 nginx:v1

扫雷案例

1、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

[root@docker] yum -y install httpd

2、将Centos-7.repo和epel-7.repo文件上传至/root目录

[root@docker] ls /root/
Centos-7.repo epel-7.repo

3、# 将saolei.zip包放置/目录下

[root@docker ~] rz -E
rz waiting to receive.

4、新建dockerfile

[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 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"]

5、新建init.sh脚本

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

6、构建saolei:v1镜像

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

7、# 运行saolei容器

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