Docker部署web应用

一、准备

下载jdk、tomcat；

准备好应用war包：sample.war

启动脚本start_tomcat.sh

#!/bin/bash

#Desc:
#       Start tomcat with docker containerstart.

echo "Start Tomcat ..."

# Export java path
export PATH=$PATH:/usr/local/java/bin
# Display Container ipaddress
ifconfig
# Start tomcat
bash /usr/local/tomcat/bin/catalina.sh run

修改tomcat的server.xml，在Host节点下加上：

<Context path="/sample" docBase="/webapps/sample.war" reloadable="false" workDir="/tomcat_work" />

二、制作镜像

编辑Dockerfile：

FROM ubuntu:16.10
MAINTAINER yanjunlu<yanjunlu1980@gmail.com>

RUN mkdir /usr/local/java \
&& mkdir /usr/local/tomcat
COPY jre1.8.0_131 /usr/local/java
COPY apache-tomcat-7.0.79 /usr/local/tomcat
ADD start_tomcat.sh start_tomcat.sh
RUN chmod a+x start_tomcat.sh
EXPOSE 8080

编译镜像：

docker build -t="test_tomcat" .

启动镜像：

docker run -it -d -v /home/lu/docker/webapps:/webapps -p 8088:8080 test_tomcat

docker exec -it d79 bash

./start_tomcat.sh

查看容器IP：

docker inspect --format '{{ .NetworkSettings.IPAddress }}' 容器id
