Testing it locally

You can run the application by issuing the following command:

mvn install spring-boot:run

The application is available under http://localhost:8080/ and runs (by default) with an in-memory H2 database. Log in with the admin account admin/admin.

In the dev profile (which will be activated if no profile is specified) the application starts with an embedded in-memory H2 database.

Running the released Docker image

The released docker image is available on Docker Hub.

docker run -d -p 8080:8080 fred4jupiter/fredbet

Building your own Docker image

mvn clean install
docker build -t fred4jupiter/fredbet .
docker run -d -p 8080:8080 fred4jupiter/fredbet

This will build (and run) an image with name fred4jupiter/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.
