    /* Every poll must have it's unique uuid, use a generator to create one */
    "uuid": "06c5a013-4e71-439a-b8da-65e35b6419f0",

    /* URL of the IRMA server */
    "irma": "https://attr.auth.amsterdam.nl",

    /* URL of Node server, optional with port number */
    "nodeUrl": "http://localhost:8000",

    /* Port number the Node server listens to */
    "port": 8000,

Install

cd voting_node
docker build -t voting_node .

Run

1. Make sure IRMA is running (see https://github.com/Amsterdam/di-irma-server)
2. Add the URL of IRMA to server/*.json)
3. Make sure PostgreSQL is running and a user is created:

cd dev/db
./postgres.sh

Run locally without Docker

cd voting_node/server
npm install
cd ../../dev
./start.sh

Run production mode

cd voting_node
docker run --rm -p80:8000 -e NODE_ENV=production -e CONFIG=config-prod.json -e PRIVATE_KEY="$(cat ../dev/private_key.pem)" -e POSTGRES_HOST=localhost -e POSTGRES_DATABASE=postgres -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=hj21kjy --name voting_container voting_node

Replace POSTGRES_HOST=localhost with IP address of Postgres.

Run development mode

cd voting_node
cp ../dev/config-dev.json server
docker build -t voting_node .
docker run -it --rm -p80:8000 -e CONFIG=config-dev.json -e PRIVATE_KEY="$(cat ../dev/private_key.pem)" -e POSTGRES_HOST=localhost -e POSTGRES_DATABASE=postgres -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=hj21kjy --name voting_container voting_node

Replace POSTGRES_HOST=localhost with IP address of Postgres.

How to spin up a local development enviroment from scratch

generate the keys

$ ./dev/keygen.sh

copy the public_key.pem to irma_server_constainer/config/public_key.pem

$ cp ./dev/keypair/public_key.pem ../irma_server_container/config/public_key.pem

copy the private_key.pem the the local express server ./voting_node/server

$ cp ./dev/keypair/private_key.pem ./voting_node/server

install ngrok

• run ./dev/ngrok/ngrok.sh in a separate terminal
• copy the url generated for port 8088 and set it in ./dev/config-dev.json (irma setting) and in the docker-compose.yml for the BASE_URL environment variable
• the ngrok tunnel will be available for 8 hours or until the ngrok session is exited. The update of the irma setting in config-dev.json has to be done each time the ngrok session expires or is restarted.

create and configure the certificates

• run ./dev/keygen.sh to generate the certificates (public_key.pem en private_key.pem) in ./dev/keypair
• in irma_server_container project:
  • copy the public_key.pem to the irma_server_container in de config folder
  • configure "key_file": "./config/public_key.pem" in ./config/irmaserver.json
• this project:
  • copy private_key.pem to ./dev/

run the dockers

• run docker-compose build

• build the irma_server_container image and rename this to irmaservercontainer_irma

  • docker rename <old-name> irmaservercontainer_irma

• run docker-compose up and go to http://localhost:8000
