As the work for Alf.io v2 has started, this branch may contain unstable and untested code. If you want to build and deploy alf.io by yourself, we strongly suggest you to use the 2.0-M2-maintenance branch, as it contains production-ready code.


You should have installed Java version 11 (e.g. Oracle's, OpenJDK, or any other distribution) to build and run alf.io. Please note that for the build process the JDK is required.

Postgresql version 9.6 or later.

Additionally, the database user that creates and uses the tables should not be a "SUPERUSER", or else the row security policy checks will not be applied.

Run on your machine

Gradle Build

This build includes a copy of the Gradle wrapper. You don't have to have Gradle installed on your system to build the project. Simply execute the wrapper along with the appropriate task, for example

./gradlew clean

Running with multiple profiles

You must specify a project property at the command line, such as

./gradlew -Pprofile=dev :bootRun

The local "bootRun" task has the following prerequisites:

  • a PostgreSQL (version 9.6 or later) instance up and running on localhost:5432
  • a postgres user having a password: password
  • a database named alfio

once started, alf.io will create all the required tables in the database, and be available at http://localhost:8080/admin. You can log in using the default Username admin and the password which was printed on the console.

Note: if you want to test without installing a pgsql instance, we have configured the following tasks:

  • startEmbeddedPgSQL
  • stopEmbeddedPgSQL

So, in a terminal first launch pgsql:

./gradlew startEmbeddedPgSQL

In another one launch alf.io

./gradlew -Pprofile=dev :bootRun

When you are done, kill the pgsql instance with:

./gradlew stopEmbeddedPgSQL

The following profiles are supported

  • dev
  • dev-pgsql
  • docker-test

You can get a list of all supported Gradle tasks by running

./gradlew tasks --all

You can configure additional System properties (if you need them) by creating the following file and putting into it one property per line:

vi custom.jvmargs

Please be aware that since this file could contain sensitive information (such as Google Maps private API key) it will be automatically ignored by git.

For debug

Add a new line with: -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005 in custom.jvmargs

Developing alf.io

Importing the Gradle project into Intellij and Eclipse both work.

Note: this project uses Project Lombok. You will need to install the corresponding Lombok plugin for integration into your IDE.

Check dependencies to update

./gradlew dependencyUpdates


Container images are available on https://hub.docker.com/r/alfio/alf.io/tags.

alf.io can also be run with Docker Compose:

docker-compose up

If you plan on using Docker Compose to run alf.io in production, then you need to make a couple of changes:

  • Add a mapping for port 8443
  • Handle SSL termination (e.g. with something like tutum/haproxy)
  • Remove the SPRING_PROFILES_ACTIVE: dev environment variable

Test alf.io application

  • Check alfio logs: docker logs alfio
  • Copy admin password in a secure place
  • Get IP of your docker container: (only on Mac/Windows, on Linux the proxy will bind directly on your public IP)
    • boot2docker IP on Mac/Windows
  • Open browser at: https://DOCKER_IP/admin
  • Insert user admin and the password you just copied

Generate a new version of the alfio/alf.io docker image

  • Build application and Dockerfile:

    ./gradlew distribution
  • Enter the directory:

    cd build/dockerize
  • Create docker image:

    docker build -t alfio/alf.io .
