写在前面
看完dokcer相关的书籍，正好有个项目要这样搞，所以自己练习一下。
当作一百世一样。这里的道理很明白:我思故我在,既然我存在,就不能装作不存在。无论如何,我要为自己负起责任。——王小波《三十而立》
结构图：
这里仅作为一种学习，一般这种负载的话，nginx是放到主机侧的， javaweb(tomcat)应用放到容器里。
效果
新建文件夹。

构建nginx配置文件内容
这个的配置文件，在容器运行的时候通过 -v参数与 容器内部共享。方便后期参数更改

构建nginx镜像
docker build -t uag/uag_nginx .
二，java web(tomcat)应用镜像构建

from dordoka/tomcatmaintainer liruilongcopy uaweb.war /opt/tomcat/webapps/uaweb.warexpose 8080entrypoint [ "/opt/tomcat/bin/catalina.sh", "run" ] |
上传对应的war包
|

|
lsdockerfile uaweb.war |
构建镜像
docker build -t uag/uag_tomcat .
三，运行容器 nginx镜像
|
1
|
docker run -d -p 8099:8099 --name uag_nginx -v $pwd/nginx/nginx.conf:/etc/nginx/nginx.conf uag/uag_nginx nginx |
java web(tomcat)镜像

docker run -it -d -p 8089:8080 --name uag_app_1 uag/uag_tomcat docker run -it -d -p 8079:8080 --name uag_app_2 uag/uag_tomcat docker run -it -d -p 8069:8080 --name uag_app_3 uag/uag_tomcat |
查看运行的容器

构建好镜像上传仓库：
嗯，需要注册一个docker hub账号，然后登录，需要镜像前面加 账户名/
