 1 | # apache-tomcat-docker-sample
 2 | 
 3 | - docker sample 
 4 | - apache(mod_jk) => tomcat => servlet
 5 | 
 6 | ## dependencies
 7 | 
 8 | - virtualbox
 9 | - docker
10 | - docker-machine
11 | - docker-compose >= 1.6.0
12 | 
13 | must use docker-compose >= 1.6.0. because we use version 2 of the Compose file format.
14 | 
15 | see: https://blog.docker.com/2016/02/compose-1-6/
16 | 
17 | ## how to use
18 | 
19 | ```
20 | $ docker-machine create --driver virtualbox apache-tomcat-docker-sample
21 | ```
22 | 
23 | ```
24 | $ eval "$(docker-machine env apache-tomcat-docker-sample)"
25 | $ docker-compose up
26 | ```
27 | 
28 | ```
29 | $ mvn clean package
30 | ```
31 | 
32 | then, access browser
33 | 
34 | - http://{ip}/
35 | 
36 | ip is
37 | 
38 | ```
39 | $ docker-machine ip apache-tomcat-docker-sample
40 | ```
41 | 
42 | ## tips
43 | 
44 | ```
45 | $ docker exec -it httpd-container /bin/bash
46 | $ docker exec -it tomcat-container /bin/bash
47 | ```
