Testing it locally
Building and running with Java 21 and Maven installed
You can run the application locally if you have Java 21 and Maven installed. Run the following command:
mvn install spring-boot:runIt will build and run the application. The web UI will be available at http://localhost:8080/ and runs (by default) with an in-memory H2 database. Log in with the admin account admin/admin.
Building and running with Docker and Docker Compose
If you have Docker and Docker Compose installed you can build the application with:
docker compose --profile app buildThe next command starts the container connecting to the postgres database:
docker compose --profile app up -dRunning the released Docker image
The released docker image is available on:
Docker Hub
You can browse the available releases at Docker Hub. Please check
for the latest released version or use the latest tag for current development image (not stable).
docker run -d -p 8080:8080 fred4jupiter/fredbet:<VERSION_TAG>Use the last version tag published or leave empty to use the latest one.
Github Container Registry
docker run -d -p 8080:8080 ghcr.io/fred4jupiter/fredbet:<VERSION_TAG>Building your own Docker image
mvn clean install
docker build -t fredbet .
docker run -d -p 8080:8080 fredbetThis will build (and run) an image with name fredbet.
Running with Docker Compose
There are some docker compose files available to run the application e.g. with a separate database. This configuration is recommended for production use.
You can find the docker compose example files in folder extra/docker-compose and its subdirectories.

Other properties depend on your production setup (see possible properties above). Add also the properties for your database connection (see above).
Docker Compose with Traefik, Postgres, Let´s Encrypt Integration and AWS S3 Backup
Another option is to run all on a virtual machine with a Docker Compose file. You can use the example located in
extra/docker-compose/traefik_letsencrypt. Copy the .env.template to .env and set the values accordingly.
