Installation

Knowledge Needed

A good understanding of docker, docker-compose & nginx

Prerequisites

Docker

Installation instructions for Docker can be found here.

Run docker -v in terminal to check if docker has been installed correctly:

$ docker -v
Docker version 20.10.9, build c2ea9bc90b

Docker Compose

Installation instructions can be found here.

Run docker compose version in the terminal to check if docker compose has been installed correctly:

$ docker compose version
Docker Compose version 2.0.1

Backend Setup

Getting Code for Backend

Clone the repo

git clone https://github.com/Sunbird-RC/demo-education-registry.git
git checkout federated_edu_registry

This will create a demo-education-registry folder in the current working directory. Goto that folder

Setting up a Registry Instance

In the demo-education-folder, run the following command

docker compose up -d

This will start all the required services. Once all the services are started, Go to the browser and open http://localhost:8080/auth/. This will open up the keycloak admin portal. Use username as admin and password as admin.

Once logged in, navigate to clients. Select admin-api. Go to credentials tab and click on regenerate secret. Copy this secret. Create a .env file in the project repo and add KEYCLOAK_SECRET it as an environment variable with the value of the secret in the following format KEYCLOAK_SECRET=<copied_secret>

Recreate the registry so that it reflects the keycloak secret. This can be done using

docker compose up -d --force-recreate --no-deps registry

If any service has not started you can recreate that service with the same command

docker compose up -d --force-recreate --no-deps <service_name>

Check if all the services are started

docker compose ps

Setting up Keycloak

Adding Roles

Open http://localhost:8080/auth/ in the browser and navigate to roles in the left side pane. Click on Add Role.

Create admin, scholarship, trial-scholarship roles

Create admin user in keycloak

Update the credential for the admin user. Ex: abcd@123

Assign admin role to this user

Now you can use the admin user to create issuers, create schemas, issue VCs and view issued VCs You can follow the following jupyter notebook which has all the APIs.

Note:-

  • Schemas for EER are present in the following location

Assign `admin` role to the issuer

  • An issuer will require admin role to create schemas in the registry.

  • Goto keycloak admin console, http://localhost:8080/auth/

  • Goto Groups and double-click on Issuer

  • If Issuer group is not found, then you need to create an issuer first. The APIs to create the issuer is documented in the above jupyter notebook.

  • Goto Role Mappings and select admin from Available Roles and click Add Selected

The issuer will require the same roles that are configured in the schema configuration to issue VCs for that schema. In the below sample schema, ScholarshipForTopClassStudents it requires a user to have scholarship role. Only if the issuer contains that role then he will be able to issue VC. Similar to the above steps, you can assign the scholarship roles to the issuer to get access.

Setting up Redash

How to configure

Once all the services are up and running, run the following command

docker compose run --rm server create_db

This command will run migrations for redash

Once this is successful, open the http://localhost:5678 in the browser. The following screen should be displayed

You can create the admin user on this screen. Once you create the admin user, the admin user will be displayed. Here you can create a dashboard, queries etc. Create a dashboard and queries here

Connect to the data source

  • On the home page click on Connect a Data Source

  • Search for Clickhouse

  • Add these details on the form to set up a connection with Clickhouse

Now that you have connected to Clickhouse, you can create queries. Once a query is created, you can add your visualization for the same.

Create a query and visualization

Create a visualization showing the total number of VCs issued for PreMatricScholarship schema.

  • Goto Queries tab

  • Click on Create your first Query

  • Paste the below query and click on Save

select count(*) as count from default.prematricscholarship

  • Rename this query New Query to Total PreMatricScholarship VC Issued

  • Click on Save and click on Publish

  • Click on Show Data Only

  • At the bottom click on Blue Play Button

  • Click on + New Visualization

  • Create a visualization with the below values. And click on Save

  • Click on Create and click on Dashboard. You can give a name to your dashboard and click on Save

  • Click on Add Widget and select the new visualization created. And click Add to Dashboard

  • Click on Done editing and click on Publish

  • Now the dashboard can be shared with other members. Click on Share and enable public access and copy the URL and share it with others for viewing the dashboard

Frontend Setup

  • Make sure your node and npm versions are - node v16.13.1 (npm v8.1.2)

You can also manage these versions using Node Version Manager
