This is to help developers to get fast a running development environment for debugging.
To use it in production you may need to carefully review all configurations and adjust.
This Docker environment is to test/develop a Turbine app using a docker test database.
The build should take place outside the docker container.
It is based on one docker-compose.yml file and two Dockerfiles.
Docker compose uses currently two customized services: app (maven:3-jdk-8) and db (mysql:latest).
To run the build with maven do this outside of the container using following mvn command:
mvn install -Pdocker
IF you have already generated this with mvn archetype:generate within the same host environment this step could be omitted.
cd <project>/target/docker-resources docker compose config
Important: Check that /m2repo is properly mapped to your local maven repository in docker-compose.yml!
docker compose build --no-cache docker compose up --detach
First time building might take a couple of minutes.
You may use the command docker compose or docker-compose, but will slightly different results.
The app service uses later a volume, which maps to the local maven repository, which you may need/not need. The db service uses mysql-latest (currently 8.x), you may replace it with a fixed release tag.
If previously build, you may want to delete all volumes (this will delete all tables in /var/lib/mysql monted in volume db_data_) and containers
docker-compose down -v
docker-compose build --no-cache
.. optionally build it separately docker-compose build --no-cache --build-arg DB_CONTEXT=./docker-resources/db db
.. building app service first/only requires removing the dependency in docker-compose.yml(comment depends_on: db) docker-compose build --no-cache app
DB_CONTEXT is set to allow starting the db container standalone (in folder db, e.g. with docker build --tag my-db .) to test it. CAVEAT: The db service is build and populated until now with hard coded data. It is a dependency for the service app (see app/Dockerfile).
Start both services in one step (add -d for detached mode)
.. or doing it in background, requires second start command
docker-compose up -d docker-compose start
This will start first the db service, then the app service. Jetty is run exposing the webapp to http://localhost:8081/app. By default remote debugging is activated (port 9000), which could be removed/commented in docker-compose.yml. You could follow the logs with docker-compose logs -f app or docker-compose logs -f db.
Optionally Check system or cleanup, e.g. with docker-compose down, docker-compose down -v or docker sytem prune (removes any container on system).
If services are already installed, activate/start by docker-compose up

Currently the docker-compose is generated once more, if starting the containers, this will overwrite m2repo and may result in errors.
If not yet done, build on the host with mvn clean install -f ../pom.xml -Pdocker.
The security test is skipped by default as it requires a running mysql. It tests many of the Fulcrum Torque Turbine security aspects, you may activate it by calling in the root of the container in the shell (e.g. with docker-compose run --rm app /bin/sh):
mvn test -DskipTests=false
You may reset MAVEN_OPTS, which is by default set in settings.xml
a running docker service db
Check/update proper settings of Db connection URL in
If you have not initialized docker, when creating the archetype instance, you may have to edit TorqueTest.properties and adapt the url from localhost to db.
If running tests inside container, URL setting in TorqueTest.properties should be:
torque.dsfactory.turbine.connection.url = jdbc:mysql://db:3306/turbine?serverTimeZone=UTC
Then run in target/docker-resources a docker compose run command:
docker compose run app /bin/sh #mvn test -DskipTests=false
Of course, if running inside the container, you should exit and you might have to restart the app service.
On the other side, if running the tests outside the container the setting should be :
torque.dsfactory.turbine.connection.url = jdbc:mysql://localhost:13306/turbine?serverTimeZone=UTC
This depends of course on the db ports settings in docker-compose.yml.
Run in project root
mvn test -DskipTests=false
docker-compose run db /bin/sh
Extract data in db service
mysql -u root -h db -P 3306 -p
docker-compose exec db mysql -u root --password=... -e "show databases;" --build-arg DB_CONTEXT=./docker-resources/db docker-compose exec db sh -c 'exec mysqldump --all-databases -uroot -p...' --build-arg DB_CONTEXT=./docker-resources/db > dump.sql
This will start app (and db as app depends on db):
docker-compose run app /bin/sh
In the container, check:
ls -la /myapp // should list pom.xml ...
Start Docker Desktop, you might not get an error immediately if not, but only when shared volumes are created (like
Error response from daemon: error while creating mount source path ‘/run/desktop/mnt/host/wsl/docker-desktop-bind-mounts/..’: mkdir /run/desktop/mnt/host/wsl/docker-desktop-bind-mounts/.. file exists
You may have to replace in volume mapping for host repo path (maven localRepository) backslashes with slashes “/” in docker-compose.yml or better rerun the maven build.
Check COMPOSE_CONVERT_WINDOWS_PATHS, https://docs.docker.com/compose/reference/envvars/#compose_convert_windows_paths
If an image download fails, try Docker->Network->Update DNS to 22.214.171.124
ERROR, when starting docker-compose up/start:
ERROR: for docker-resources_db_1 Cannot start service db: driver failed programming external connectivity on endpoint docker-resources_db_1 ... Error starting userland proxy: mkdir /port/tcp:0.0.0.0:13306:tcp:...:3306: input/output error"
Check file permissions of archetype generated files (chmod -R a+rw docker-resources, chmod -R a+rw src).
If you generated the project with windows shell, but run the docker form wsl you have to regenerate docker-compose.yml with unix pathes running this command again
mvn install -Pdocker
If you want to run from Dockerfile ..
docker-compose rm -v
docker rmi $(docker images -q)
docker volume inspect <containerid> // delete intermediate images, volumes docker rmi $(docker images --filter "dangling=true" -q) docker volume rm $(docker volume ls -qf dangling=true) # or delete while building docker build --rm # cleans all containers docker system prune # stops all running containers docker stop $(docker ps -a -q)
