1. Deploy tomcat
1. Ctrl+Alt+t to open the command
2. Obtain root privileges:
sudo su
3. Enter the password
4. Create a folder tomcat7, the command is as follows, and switch to this directory:
mkdir tomcat7
cd tomcat7
5. In the tomcat7 folder, create a Dockerfile
touch Dockerfile
6. Edit Dockerfile
vim Dockerfile
7. Complete the following commands
8. Build the image with the following command
docker build -t craig/tomcat .
9. The following command will run Tomcat and expose port 8080 of the container to port 8080 of the host machine
docker run -p 8080:8080 craig/tomcat
10. Test tomcat has been started
Second, deploy the java web project
1. Create a software folder in the root root directory to store the java web project
cd ../ cd .. / cd root mkdir software
2. Move the project under /home/zhaos to the software folder just created (hello-lee is the project name)
mv /home/zhaos/hello-lee /root/software
3、查看所有镜像，找到tomcat镜像ID
docker images
4、启动容器（挂载），将software文件夹下的项目同步到tomcat镜像中并进入到该镜像中（其中镜像ID是上一步中查找到的tomcat镜像ID）
docker run -i -t -v /root/software/:/mnt/software/ 镜像ID /bin/bash
5、将项目移动到tomcat中webapps文件夹下
mv /mnt/software/hello-lee /usr/local/tomcat/webapps
6、更新镜像（如果不先更新，则执行第7步会失败）
apt-get update
7、下载安装vim
apt-get install vim
8、编写运行脚本
vim /root/run.sh
9、脚本内容如下
#!/bin/bash source ~/.bashrc sh /usr/local/tomcat/bin/catalina.sh run
10、添加脚本执行权限
chmod u+x /root/run.sh
11、查看所有容器
docker ps -a
12、创建java web 镜像
docker commit 上一步的容器ID zhaos/javaweb:0.1
13. View all mirrors
docker images
14. Start the mirror
docker run -d -p 58080:8080 zhaos/javaweb:0.1 /root/run.sh http://www.cnblogs.com/Neonuu/p/5632229.html
