How to run it ?

You can run an instance easily by pulling the docker image and execute by following :

docker run klask/klask.io


an example of a docker-compose.yml :

version: '2'
    image: klask/klask.io:latest
      - 8080:8080
      - /mnt/svn:/repo
      - ./data:/klask-data
      - ./application-docker.yml:/application-docker.yml

/mnt/svn is the path to my repositories
./data is the location where elasticsearch files and database were saved.
The optional file application-docker.yml can overrides all properties defined in application.yml and application-docker.yml


Before you can build this project, you must install and configure the following dependencies on your machine:

  1. Node.js: We use Node to run a development web server and build the project. Depending on your system, you can install Node either from source or as a pre-packaged bundle.

After installing Node, you should be able to run the following command to install development tools (like Bower and BrowserSync). You will only need to run this command when dependencies change in package.json.

npm install

We use Gulp as our build system. Install the Gulp command-line tool globally with:

npm install -g gulp

Run the following commands in two separate terminals to create a blissful development experience where your browser auto-refreshes when files change on your hard drive.


Bower is used to manage CSS and JavaScript dependencies used in this application. You can upgrade dependencies by specifying a newer version in bower.json. You can also run bower update and bower install to manage dependencies. Add the -h flag on any command to see how you can use it. For example, bower update -h.

Building for production

To optimize the klask.io client for production, run:

./mvnw -Pprod clean package

This will concatenate and minify CSS and JavaScript files. It will also modify index.html so it references these new files.

To ensure everything worked, run:

java -jar target/*.war --spring.profiles.active=prod

Then navigate to http://localhost:8080 in your browser.


Unit tests are run by Karma and written with Jasmine. They're located in src/test/javascript/ and can be run with:

gulp test

To run with docker in production :

Utiliser les fichiers docker-compose dans src/main/docker

docker-compose -f elasticsearch.yml up -d
docker-compose -f postgresql.yml up -d

java -jar target/*.war --spring.profiles.active=prod

Continuous Integration

To setup this project in Jenkins, use the following configuration:
