网络设定
# 创建网络
brctl addbr br0
ip link set dev br0 up
ip addr add 192.168.2.1/24 dev br0

# 创建容器
# 方法1
DB=$(docker run -d --name db pandy/centos7-postgresql931)
pipework br0 $DB 192.168.2.100/24
# 方法2
docker run -d --name db pandy/centos7-postgresql931

supervisord.conf文件代码
[supervisord]
nodaemon=true

[program:tomcat]
command=/opt/tomcat/bin/startup.sh
构建:
docker build -t pandy/centos7-java7-tomcat7 .   //构建
docker run -t -i -d --name web -p 81:8080 pandy/centos7-java7-tomcat7 /bin/bash //创建, 这个不会自动启动tomcat
docker run -d --name web -p 81:8080 pandy/centos7-java7-tomcat7 /usr/bin/supervisord  //这个会自动启动tomcat
docker run -t -d --name web -p 81:8080 -v /home/pandy/docker-resources/tomcat/webapps:/opt/tomcat/webapps pandy/centos7-java7-tomcat7 /usr/bin/supervisord  //这个会自动启动tomcat, 并挂载webapps, 同时可以挂载logs, work等文件夹进去，注意，现在为什么挂载要使用/opt/tomcat7，而不是/opt/tomcat？不是已经做软链接了么？

注意:关于tomcat,在http://support.inovatrend.com/confluence/display/PUBLOG/Java,+Tomcat+and+Docker,介绍
比如:在run追加参数-e "JAVA_OPTS=-Dspring.profiles.active=demo -Xmx1024m", 可以设定一些变量.
但是https://registry.hub.docker.com/u/maluuba/tomcat7/看到
docker run --cap-add SYS_PTRACE -it -p 8080:8080 -e JAVA_OPTS='-Dsome.property=value' -e Xmx=2048m -v deployment:/deployment maluuba/tomcat7
待测试看到底是哪种情况是对的




Postgresql
*********************************************************************
原文:https://registry.hub.docker.com/u/autenta/centos-postgresql/
Image for CentOS 6 and PostgreSQL 9.3 that create database with sv_SE.UTF8 locale.
Source: https://github.com/jotu/docker-centos-postgresql

OBS! This is a simple version and should only be used in development or testing.
Getting Started
You can build this container from Github via
docker pull autenta/centos-postgresql

To run the container you can do the following:
docker run -p 5432:5432 -d -t autenta/centos-postgresql
psql -U postgres -h localhost -p 5432
安装后默认密码为空.

Dockerfile安装
可以使用它的Dockerfile(修改成了centos:7):
