dockerfile

1、基于基础镜像centos:7

[root@localhost ~]# vim Dockerfile 
 FROM centos:7

2、维护者信息

MAINTAINER renweiwei@example.com

3、添加Centos-7仓库

 ADD Centos-7.repo /etc/yum.repos.d/

4、添加epel-7仓库

ADD epel-7.repo /etc/yum.repos.d/

5、安装nginx软件包

RUN yum -y install nginx

6、暴露指定端口80

EXPOSE 80
CMD ["/usr/sbin/nginx","-g","daemon off;"]

7、构建镜像，镜像名称为nginx:v1

[root@localhost ~]# docker build -t nginx:v1 .
Sending build context to Docker daemon  73.88MB
Step 1/7 : FROM centos:7
 ---> eeb6ee3f44bd

nginx        latest    2b7d6430f78d   7 days ago      142MB

8、运行容器，容器名称为自己名字的全拼，映射端口88：80

[root@localhost ~]# docker run -d --name renweiwei -p 88:80 nginx:v1
e00d5b3e320b6daa18519fc8eba36cbc2ba3450ece2d60ec31269d07111e09ba
[root@localhost ~]# docker ps
CONTAINER ID   IMAGE      COMMAND                  CREATED          STATUS          PORTS                               NAMES
e00d5b3e320b   nginx:v1   "/usr/sbin/nginx -g …"   22 seconds ago   Up 21 seconds   0.0.0.0:88->80/tcp, :::88->80/tcp   renweiwei

9、进入容器，删除默认网页，写入新的默认网页，网页内容为你们自己名字的全拼

[root@localhost ~]# docker exec -it renweiwei /bin/bash
[root@e00d5b3e320b /]# cd /usr/share/nginx/
[root@e00d5b3e320b nginx]# cd html/
[root@e00d5b3e320b html]# ls
404.html  50x.html  en-US  icons  img  index.html  nginx-logo.png  poweredby.png
[root@e00d5b3e320b html]# rm -rf index.html 
[root@e00d5b3e320b html]# echo renweiwei > index.html
[root@e00d5b3e320b html]# ls
404.html  50x.html  en-US  icons  img  index.html  nginx-logo.png  poweredby.png

10、通过浏览器，能够正常访问nginx

一、扫雷案例

1、所需软件包和环境

Centos-7.repo epel-7.repo saolei.zip
server1：部署docker扫雷案例
server2：部署apache，将saolei.zip软件包上传上去

[root@server2 ~]# dnf -y install httpd
]上次元数据过期检查：3:59:44 前，执行于 2022年08月30日 星期二 11时32分04秒。
软件包 httpd-2.4.37-47.module_el8.6.0+1111+ce6f4ceb.1.x86_64 已安装。
依赖关系解决。

完毕！
[root@server2 ~]# cd /var/www/html/
[root@server2 html]# ls
saolei.zip
[root@server2 html]# systemctl disable firewalld
[root@server2 html]# vi /etc/selinux/config
SELINUX=disabled

2、编辑Dockerfile，使用基础镜像centos:7

server1:

[root@server1 ~]# vim Dockerfile 
FROM centos:7
MAINTAINER renweiwei@example.com
ADD Centos-7.repo /etc/yum.repos.d/
ADD epel-7.repo /etc/yum.repos.d/
RUN yum -y install tomcat
WORKDIR /var/lib/tomcat/webapps/
RUN curl -O  http://192.168.253.148/saolei.zip && \
unzip saolei.zip && \
RUN mv saolei ROOT
ADD init.sh /init.sh
EXPOSE 8080
CMD ["/bin/bash","/init.sh"]

~                               

[root@server1 ~]# cat init.sh
#!/bin/bash
/usr/libexec/tomcat/server start

3、构建镜像saolei:v1

[root@server1 ~]# docker build -t saolei:v1 .
Removing intermediate container 5e909dbd0574

 .

4、运行容器，指定映射端口8081:8080，容器名为自己名字的全拼

[root@server1 ~]# docker run --name renweiwei -d -p 8081:8080 saolei:v1
04dcb3ce536e6b73ee4f3d0823ee38db9a25f2d21a0e4be8854646b6fd7c938b
[root@server1 ~]# docker ps
CONTAINER ID   IMAGE       COMMAND                  CREATED          STATUS          PORTS                                       NAMES
04dcb3ce536e   saolei:v1   "/bin/bash /init.sh"     29 seconds ago   Up 26 seconds   0.0.0.0:8081->8080/tcp, :::8081->8080/tcp   renweiwei

5、使用浏览器访问http://自己docker服务器的ip/saolei.jsp，能够实现扫雷游戏的使用

二、可道云案例

1、所需软件包

Centos-7.repo epel-7.repo kodexplorer4.40.zip nginx.conf

2、创建/opt/dockerfile/kod目录，将所需的软件包和文件放置该目录下

[root@localhost ~]# cd /opt/dockerfile/kod/
[root@localhost kod]# ls
[root@localhost kod]# ls
Centos-7.repo  epel-7.repo  kodexplorer4.40.zip  nginx.txt
[root@localhost kod]# mv nginx.txt nginx.conf
[root@localhost kod]# ls
Centos-7.repo  epel-7.repo  kodexplorer4.40.zip  nginx.conf
[root@localhost kod]# cat nginx.conf 
worker_processes 1; 
events { 
	worker_connections 1024; 
}
http {
	include mime.types; 
	default_type application/octet-stream; 
	sendfile on; 
	keepalive_timeout 65; 
	server { 
		listen 80; 
		server_name localhost; 
		location / { 
			root /code; 
			index index.php index.html index.htm; 
		}
		location ~ \.php$ { 
			root /code; 
			fastcgi_pass 127.0.0.1:9000; 
			fastcgi_index index.php; 
			fastcgi_param SCRIPT_FILENAME /code$fastcgi_script_name; 
			include fastcgi_params; 
		}
	} 
}

3、在该目录下编辑dockerfile，使用基础镜像centos:7

[root@localhost kod]# vim dockerfile  
FROM centos:7
ADD Centos-7.repo /etc/yum.repos.d/
ADD epel-7.repo /etc/yum.repos.d/
RUN yum -y install nginx php-fpm php-gd php-mbstring unzip
RUN sed -i '/^user/c user=nginx' /etc/php-fpm.d/www.conf 
RUN sed -i '/^group/c group=nginx' /etc/php-fpm.d/www.conf 
COPY nginx.conf /etc/nginx/nginx.conf 
RUN mkdir /code 
WORKDIR /code 
COPY kodexplorer4.40.zip . 
RUN unzip kodexplorer4.40.zip 
RUN chown -R nginx.nginx . 
ADD init.sh /init.sh 
EXPOSE 80
ENTRYPOINT ["/bin/bash","/init.sh"]
[root@localhost kod]# cat init.sh 
#!/bin/bash 
php-fpm -D 
echo "$1" >> /etc/nginx/nginx.conf 
nginx -g 'daemon off;' 

4、构建镜像kod:v1

[root@localhost kod]# docker build -t kod:v1 .
Removing intermediate container 4c6947fb079e
 ---> c6066d8d3644
Step 12/15 : RUN chown -R nginx.nginx .
 ---> Running in 696a0f9b165a
Removing intermediate container 696a0f9b165a
 ---> 12f6067340e8
Step 13/15 : ADD init.sh /init.sh
 ---> 413e2e2d07d7
Step 14/15 : EXPOSE 80
 ---> Running in 9c86fae282c1
Removing intermediate container 9c86fae282c1
 ---> 3ac55a829c64
Step 15/15 : ENTRYPOINT ["/bin/bash","/init.sh"]
 ---> Running in 8fa129adafd3
Removing intermediate container 8fa129adafd3
 ---> 95a350fe5acf
Successfully built 95a350fe5acf
Successfully tagged kod:v1

5、运行容器，指定映射端口80:80，容器名为自己名字的全拼

[root@localhost kod]#  docker run --name renweiwei -d -p 80:80 kod:v1 '#runtime'
04808c5c8f235753c9ffbedc8872b6d5fc5007c6c42a4287cb109ab9cb8dda76
[root@localhost kod]# docker exec -it renweiwei /bin/bash
[root@04808c5c8f23 code]# tail -1 /etc/nginx/nginx.conf
#runtime

6、使用浏览器访问http://自己docker服务器的ip/index.php，能够实现可道云的使用
