自定义haproxy镜像

　　　　　　　　　　　　　　自定义haproxy镜像

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　作者：尹正杰

　　本篇博客基于自定义的CentOS镜像来自定义haproxy服务(编译安装笔记https://www.cnblogs.com/yinzhengjie/p/12113144.html)的。

一.编写Dockerfile相关文件

1>.编写编译脚本

[root@docker101.yinzhengjie.org.cn ~]# ll /yinzhengjie/softwares/dockerfile/web/haproxy
total 4
-rw-r--r-- 1 root root 467 Jan 24 11:01 build-command.sh
[root@docker101.yinzhengjie.org.cn ~]# 
[root@docker101.yinzhengjie.org.cn ~]# 
[root@docker101.yinzhengjie.org.cn ~]# chmod +x /yinzhengjie/softwares/dockerfile/web/haproxy/build-command.sh 　　　　　　
[root@docker101.yinzhengjie.org.cn ~]# 
[root@docker101.yinzhengjie.org.cn ~]# ll /yinzhengjie/softwares/dockerfile/web/haproxy
total 4
-rwxr-xr-x 1 root root 467 Jan 24 11:01 build-command.sh
[root@docker101.yinzhengjie.org.cn ~]# 
[root@docker101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/dockerfile/web/haproxy/build-command.sh 
#!/bin/bash

docker image build -t centos-haproxy:v1.8.20 .
[root@docker101.yinzhengjie.org.cn ~]#

2>.下载haproxy安装包

[root@docker101.yinzhengjie.org.cn ~]# ll /yinzhengjie/softwares/dockerfile/web/haproxy/
total 4
-rwxr-xr-x 1 root root 467 Jan 24 11:01 build-command.sh
[root@docker101.yinzhengjie.org.cn ~]# 
[root@docker101.yinzhengjie.org.cn ~]# ll
total 2036
-rw-r--r-- 1 root root 2083917 Jan 24 06:12 haproxy-1.8.20.tar.gz
[root@docker101.yinzhengjie.org.cn ~]# 
[root@docker101.yinzhengjie.org.cn ~]# cp haproxy-1.8.20.tar.gz /yinzhengjie/softwares/dockerfile/web/haproxy/
[root@docker101.yinzhengjie.org.cn ~]# 
[root@docker101.yinzhengjie.org.cn ~]# ll /yinzhengjie/softwares/dockerfile/web/haproxy/
total 2040
-rwxr-xr-x 1 root root     467 Jan 24 11:01 build-command.sh
-rw-r--r-- 1 root root 2083917 Jan 24 11:05 haproxy-1.8.20.tar.gz
[root@docker101.yinzhengjie.org.cn ~]# 
[root@docker101.yinzhengjie.org.cn ~]#

3>.编写haproxy的配置文件

[root@docker101.yinzhengjie.org.cn ~]# ll /yinzhengjie/softwares/dockerfile/web/haproxy/haproxy.cfg 
-rw-r--r-- 1 root root 796 Jan 24 12:11 /yinzhengjie/softwares/dockerfile/web/haproxy/haproxy.cfg
[root@docker101.yinzhengjie.org.cn ~]# 
[root@docker101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/dockerfile/web/haproxy/haproxy.cfg 
global
    maxconn 100000
    chroot /yinzhengjie/softwares/haproxy
    stats socket /yinzhengjie/softwares/haproxy/haproxy.sock mode 600 level admin
    uid 99
    gid 99
    daemon
    pidfile /yinzhengjie/softwares/haproxy/run/haproxy.pid

defaults
    option http-keep-alive
    option  forwardfor
    option redispatch
    option abortonclose
    maxconn 100000
    mode http
    timeout connect 300000ms
    timeout client  300000ms
    timeout server  300000ms

listen status_page
    bind 0.0.0.0:8888
    stats enable
    stats uri /haproxy-status
    stats auth    admin:yinzhengjie
    stats realm "Welcome to the haproxy load balancer status page of YinZhengjie"

listen WEB_PORT_80
    bind 0.0.0.0:80
    mode http
    server web01 172.200.3.101:8080 check inter 3000 fall 3 rise 5
[root@docker101.yinzhengjie.org.cn ~]# 
[root@docker101.yinzhengjie.org.cn ~]#

4>.编写运行haproxy的脚本

[root@docker101.yinzhengjie.org.cn ~]# ll /yinzhengjie/softwares/dockerfile/web/haproxy/run_haproxy.sh 
-rw-r--r-- 1 root root 833 Jan 24 11:32 /yinzhengjie/softwares/dockerfile/web/haproxy/run_haproxy.sh
[root@docker101.yinzhengjie.org.cn ~]# 
[root@docker101.yinzhengjie.org.cn ~]# chmod +x /yinzhengjie/softwares/dockerfile/web/haproxy/run_haproxy.sh 
[root@docker101.yinzhengjie.org.cn ~]# 
[root@docker101.yinzhengjie.org.cn ~]# ll /yinzhengjie/softwares/dockerfile/web/haproxy/run_haproxy.sh 
-rwxr-xr-x 1 root root 833 Jan 24 11:32 /yinzhengjie/softwares/dockerfile/web/haproxy/run_haproxy.sh
[root@docker101.yinzhengjie.org.cn ~]# 
[root@docker101.yinzhengjie.org.cn ~]# 
[root@docker101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/dockerfile/web/haproxy/run_haproxy.sh 
#!/bin/bash
#

#指定haproxy的配置文件并运行haproxy服务
haproxy -f /etc/haproxy/haproxy.cfg

#温馨提示,我们使用"tail -f"命令作为容器的守护进程,这样就可以在容器内重启haproxy服务,但是使用"tail -f"查看的文件尽量不要是日志文件哟,因为我们执行该命令的目的并不是为了查看日志,如果查看日志的话可能会带来不必要的IO损耗.
tail -f /etc/hosts
[root@docker101.yinzhengjie.org.cn ~]# 
[root@docker101.yinzhengjie.org.cn ~]#

5>.启动tomcat容器

　　此过程可参考我之前的笔记:
　　　　https://www.cnblogs.com/yinzhengjie/p/12230043.html

二.编写Dockerfile并编译成镜像

1>.编写Dockerfile文件

[root@docker101.yinzhengjie.org.cn ~]# ll /yinzhengjie/softwares/dockerfile/web/haproxy/Dockerfile 
-rw-r--r-- 1 root root 1301 Jan 24 12:16 /yinzhengjie/softwares/dockerfile/web/haproxy/Dockerfile
[root@docker101.yinzhengjie.org.cn ~]# 
[root@docker101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/dockerfile/web/haproxy/Dockerfile

#解压haproxy文件,ADD指令会自动帮咱们解压haproxy-1.8.20.tar.gz该文件

#后台启动haproxy服务
COPY haproxy.cfg /etc/haproxy/haproxy.cfg

#将运行haproxy的脚本添加到指定的环境变量中
copy run_haproxy.sh /usr/bin/run_haproxy.sh

#运行haproxy
CMD ["/usr/bin/run_haproxy.sh"]

三.验证haproxy功能

1>.web服务验证成功

2>.访问haproxy的状态页
