Dockerfile构建基于centos的tomcat7+activiti5

1.准备tomcat7

下载地址：https://tomcat.apache.org/download-70.cgi

下载文件名：tar.gz (pgp, sha512)

2.准备jdk8

下载地址：https://www.oracle.com/technetwork/cn/java/javase/downloads/jdk8-downloads-2133151-zhs.html

下载文件名：jdk-8u181-linux-i586.tar.gz

3.准备mysqlr的jar包

mysql-connector-java-5.1.35.jar

4.准备activiti-explorer的war包

下载地址：https://github.com/Activiti/Activiti/releases/download/activiti-5.22.0/activiti-5.22.0.zip

a.解压activiti-5.22.0.zip，进入activiti/wars目录，找到activiti-explorer\WEB-INF\classes下的db.properties配置文件并打开，修改下数据库连接信息

db=activiti

jdbc.driver=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql://localhost:3306/activiti

jdbc.username=root

jdbc.password=123456

b.添加jar包

将mysql-connector-java-5.1.35.jar驱动包拷贝到activiti-explorer\WEB-INF\lib目录下

c.清空tomcat的webapps中的所有

d.把activiti-explorer目录复制到tomcat的webapp目录下，将activiti-explorer重命名为ROOT

5.编写Dockerfile文件

FROM centos

MAINTAINER dengyunshuo "dengyunshuo@163.com"

RUN mkdir -p /home/java/jdk8

ADD jdk8 /home/java/jdk8

RUN mkdir -p /home/java/tomcat7

ADD tomcat7 /home/java/tomcat7

ENV JAVA_HOME /home/java/jdk8

ENV CATALINA_HOME /home/java/tomcat7

ENV PATH $PATH:$JAVA_HOME/bin:$CATALINA_HOME/bin

EXPOSE 8080

CMD ["/home/java/tomcat7/bin/catalina.sh","run"]

6.构建镜像

docker build -t activiti5:0.0.1 .

docker images

7.启动容器

docker run -d -p 8081:8080 --name activiti5 activiti5:0.0.1

docker ps -a

8.访问地址
