MedSky

MedSky is a storage system that combines Hyperledger Fabric and RockFS multi-cloud storage to ensure integrity and availability of electronic health records. It uses a forked version of Medplum as the backend server to interact with the blockchain network and verify the correctness of user transactions with seamless throughput.

Prometheus-Grafana Monitor

cd prometheus-grafana
docker-compose up -d

RockFS

You can configure Cloud Addresses in config/accounts.json

git clone https://github.com/jose-bernardo/RockFS
cd RockFS
sh ./install.sh

cd DepSpacito
sh run.sh
sh ./run.sh

Medplum

Requirements

nvm install 20

Installation

git clone https://github.com/jose-bernardo/medplum
cd medplum
npm i
npm run build:fast

Running the Medplum server

You can configure RockFS address in medplum.config.json

cp -r ../fabric-network/organization packages/server # copy Fabric crypto material
docker-compose up -d # deploy Redis and PostgreSQL database containers
cd packages/server
npm run dev

Running the Medplum app

This is only needed for login and get the JWT token and run the tests

cd packages/app
export MEDPLUM_BASE_URL="http://localhost:5555"
npm run dev

Then go to http://localhost:3000 and login with email [email protected] and password medplum_admin.

After login retrieve the JWT cookie for the K6 Grafana tests.
