Build Status


The niord-gh project contains Ghana-specific extensions for the
niord system, i.e. a system for producing and promulgating NW + NM T&P messages.

Niord is documented extensively at


The niord-web web-application, found under the niord project, constitutes the main system for producing and promulgating navigational warnings and notices to mariners.

The niord-gh-web project is an overlay web-application that customizes niord-web for use in Ghana.


  • Java 8
  • Maven 3
  • MySQL 5.7.10+ (NB: proper spatial support is a requirement)
  • JBoss Wildfly 10+
  • JBoss Keycloak 3.1+

Development Set-Up

The niord-appsrv project contains scripts for setting up Wildfly, Keycloak, etc.

However, the easiest way to get started developing on this project is to use Docker.

Starting MySQL and Keycloak

You may want to start by creating a .env file in your working directory, which overrides the environment variables (such as database passwords) used in the docker compose file.

The following commands will start two MySQL databases, one for the application server and one for Keycloak, and also run Keycloak itself.

mkdir $HOME/.niord-gh
docker-compose -f docker/docker-dev-compose.yml pull
docker-compose -f docker/docker-dev-compose.yml up -d

The initial mkdir command is just to avoid permission problems since docker would otherwise create it as owned by root.

Once this is up and running, create a Keycloak admin user (default niordadmin/keycloak) which can be used to create user groups and assign domain roles to the groups:


Enter http://localhost:8090/auth/ and check that you can log in using the Keycloak admin user.

Configuring Wildfly

Next, create and configure a Wildfly installation using:


Import or open the niord-gh project in your favorite IDE. Here we describe the IntelliJ set-up:

  • Firstly, you may want to right-click the wildfly-10.1.0-Final folder and mark the folder as excluded.
  • From Github, also check out the niord-gh parent niord projects.
  • Import the niord-gh project in IntelliJ via its pom.xml.
  • Under the "Maven Projects" also import the parent niord project.
  • In Run -> Edit configuration..., configure a new local JBoss server based on the Wilfly installation produced above.
  • Deploy "niord-gh-web:war exploded" to the server.
  • If you have only updated web resources, there is no need to re-deploy the web application. Use the "Update resources" function instead.
  • To get rid of superfluous IntelliJ code editor warnings, disable the "Declaration access can be weaker" and "Dangling Javadoc comment" inspections.

The Keycloak docker image creates an initial domain, "Master", and a Niord user, sysadmin/sysadmin, that should be used for the initial configuration of the system, whereupon they should be deleted.

Enter http://localhost:8080 and check that you can log in using the Niord sysadmin user.

Finishing touches

Import the Ghana base data into Niord:


Within a minute or so, this will import domains, areas, categories, etc. needed to run the Niord Ghana project. First clean up a bit:

  • In Niord, under Sysadmin -> Domains, click the "Create in Keycloak" button for the "NW" and "NM" domains. This will create the two domains in Keycloak.
  • In Keycloak, edit the "Sysadmin" user group. Under "Role Mappings", select first "niord-nw" then "niord-nm" and assign the "sysadmin" client roles to the group.
  • While in Keycloak, you may also want to define new user groups for editors and admins, and assign the appropriate client roles for "niord-nw" and "niord-nm" to the groups. Additionally, for admin-related groups (who should be able to manage users in Niord), assign the "manage-clients" and "manage-users" client roles of the "realm-management" client to the groups.
  • Delete the "Master" domain in Niord and the corresponding "niord-client-master" client in Keycloak.
  • Go through the configuration and settings of the Niord Sysadmin pages and adjust as appropriate.

Creating a Docker Release

First, build the niord-gh-web war using the "dist" maven profile:

cd niord-gh-web/
mvn -P dist clean install

Next, build the docker image (ensure that Wildfly is not running):

cd ../docker/
./ build ../niord-gh-web/target/niord-gh-web.war
# If successful, and if you have previously used "docker login", push to dockerhub:
./ push
