使用Dockerfile docker tomcat部署

在百度上试很多文章都不行，只有这篇可以。

宿主机为：centos64位

//安装docker

1:yum install docker

//启动docker

2:systemctl start  docker.service

3：新建web目录

mkdir test/web

4：上传tomcat和jdk到该目录（Web）下。

5:配置Dockerfile :vim Dockerfile,然后复制下面的代码到Dockerfile中，保存。记得相应修改tomcat和jdk名

#pull down centos image
FROM centos
MAINTAINER test@test.com
#copy jdk and tomcat into image
ADD ./apache-tomcat-7.0.70.tar.gz /root
ADD ./jdk-7u80-linux-x64.tar.gz /root
#set environment variable
ENV JAVA_HOME /root/jdk1.7.0_80
ENV PATH $JAVA_HOME/bin:$PATH
#define entry point which will be run first when the container starts up
ENTRYPOINT /root/apache-tomcat-7.0.70/bin/startup.sh && tail -F /root/apache-tomcat-7.0.70/logs/catalina.out

　6构建镜像

7查看新产生的镜像

[root@localhost web]# docker images keven/centos
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
keven/centos        tomcat-centos       41ab74750331        5 minutes ago       529.6 MB

8运行镜像

docker run -d -p 8090:8080 5207

　　

-p指定主机80端口与容器8080端口进行绑定

-d 指定容器运行后与当前tty分离，后台运行

5207是镜像的ID前4位。

通过  http://宿主机IP:8090,即可看见我们熟悉的tomcat首页了。
