制作xnetd镜像

制作its-xnetd:1.0 镜像
ps:xnetd 是我公司的一个自主研发的消息中间件，可以理解为 mq，本文介绍，如何将公司独有的组建放入Docker，制作成镜像。

一、前提说明

1）首先要有xnetd的应用，然后和Dockerfile在同级目录，详情如下：

|- Dockerfile
|- xnetd_bin
    \- start.sh ## 启动xnetd的脚本
    \- .config  ## xnetd相关的配置
    \- xnetd    ## xnetd应用

2） .config 配置

[sds]
Level=5
OnlineCheckSecond=100
OnlineEchoSecond=2
LocalTitle=echo;all
LocalGroup=g1
AutoDisconnect=1
cloud=none
;InitTerm=100
AlwaysAuto=1
CutLength=300
DispLevel=5
LogPath=/root/logs/xnetd

[eops]
Level=5
OnlineCheckSecond=100
OnlineEchoSecond=2
LocalTitle=echo;all
LocalGroup=g1
AutoDisconnect=1
cloud=none
;InitTerm=100
AlwaysAuto=1
CutLength=300
DispLevel=5
LogPath=/root/logs/eops/xnetd

start.sh 配置

/usr/xnetd_bin/xnetd sds 17300
sleep 2
/usr/xnetd_bin/xnetd eops 13300
sleep 2

二、开始制作镜像<font color="red" size="4">（3步）</font>

1）、编写Dockerfile文件

FROM centos:7.4.1708
MAINTAINER Will wangzhenwei@erayt.com

#上传安装xnetd
RUN mkdir  /usr/xnetd_bin
COPY xnetd_bin/xnetd /usr/xnetd_bin/xnetd
COPY xnetd_bin/start.sh /usr/xnetd_bin/start.sh
COPY xnetd_bin/.config /root/.config
RUN mkdir -p /root/logs/eops/xnetd
RUN mkdir /root/logs/xnetd

##开启端口
EXPOSE 13300  17300

#CMD ["/usr/xnetd_bin/start.sh" , "run"]
CMD sh /usr/xnetd_bin/start.sh && tail -f /root/.config

2）、执行build 命令

docker build --rm=true --no-cache=false -t its-xnetd:1.0 .

3）、启动容器

docker run -it -d --name=xnetd  -p 13300:13300 -p 17300:17300 its-xnetd:1.0

<font color="red" size="4">创建完成</font>

三、日志记录

[root@helloword xnetd]# docker build --rm=true --no-cache=false -t its-xnetd:1.0 .
