Bring up containers

From this project root directory

docker-compose build --no-cache
docker-compose up -d

Bringing down containers

If you've made a change to any of the configurations (docker, nginx, tomcat), then you just need to bring down the containers and then bring them back up. From this project root directory

docker-compose down
docker-compose build --no-cache
docker-compose up -d

Accessing tomcat

In web browser go to http://localhost:5000. You can change port 5000 in the docker-compose.yml file. Find this line:

- "5000:80"

Change 5000 to any unused port

Accessing hello world war file

By default this container will have the sample.war (hello world). You should be able to go to the following url to access:

http://localhost:5000/sample/

Changing to deploy a different war file on startup

Put your actual war file into the tomcat/webapps directory and then edit the tomcat/Dockerfile, changing the sample.war file to your new war file:

COPY webapps/sample.war /usr/local/tomcat/webapps/

change to

COPY webapps/newwarfile.war /usr/local/tomcat/webapps/

Deploying a war file through the manager

Go to your manager app (username: admin, password: admin) and you'll see a section for uploading your war file.

In your browser, go to the server running docker, http://localhost:5000/manager/html

Manager app username and password can be found in the tomcat/conf/context.xml directory if you want to change

Deploying a war file through custom shell script

Put your war file inside the tomcat/webapps directory (example: test.war) and then run the following command from within that directory

./deploy_webapp.sh test.war

You should be able to then go to http://localhost:5000/test/

Notes

This should not be used in production as is, because the tomcat manager is open to any ip with a basic username/password. Both of these can be adjusted by the config files in the tomcat directory
