Peer Health Checker

Requires

• git
• Node.js

Development

git clone this repo to your local machine, and then:

cd peer-health-checker/
npm install

This app is run twice; once for each side of a peered connection. In development, both apps will be run on the local computer.

Start up the Health app in the terminal:

PORT=5000 \
HEALTH_CHECKER_PEER_URL=http://localhost:5001 \
HEALTH_CHECKER_SELF_URL=http://localhost:5000 \
  npm run dev

Then, start up the Health Checker app in a second terminal in the same directory:

PORT=5001 \
  npm run dev

Manual Docker build

✏️ In these commands replace $DOCKER_USERNAME with your docker.com account name, and $LOCAL_IP with your external network address. (Discover with ipconfig getifaddr en0.)

docker build -t $DOCKER_USERNAME/peer-health-checker .
docker run \
  -p 8000:80 \
  -e HEALTH_CHECKER_PEER_URL=http://$LOCAL_IP:8001 \
  -e HEALTH_CHECKER_SELF_URL=http://$LOCAL_IP:8000 \
  -d $DOCKER_USERNAME/peer-health-checker
docker run \
