HAProxy - JWT

Demonstrates verifying OAuth 2 JSON web tokens in HAProxy using Lua code. See the JWT Lua library here.

Set up:

  1. Sign up for a free account at https://auth0.com/ and create a new API.
  2. Under the Scopes tab for the API, add a "read:hamsters" scope and a "write:hamsters" scope.
  3. Add a new "Machine to Machine Application" on the Auth0 site and select the API you created. Grant the "read" and "write" scopes.
  4. Replace the pem/pubkey.pem with the public key from your application's Settings tab: Applications > My App > Settings > Show Advanced Settings > Certificates > Download Certificate. (Be sure to convert it first using openssl x509 -pubkey -noout -in ./mycert.pem > pubkey.pem)
  5. Edit haproxy/haproxy.cfg, replacing the Auth0 URL with your own, such as https://myaccount.auth0.com/
  6. Create the environment with Vagrant:
    vagrant up
    
  7. Get a JSON web token (JWT) from your authentication server by following the Quick Start on the Auth0 website, under the Applications tab, for your Machine to Machine application.
  8. Make requests to https://192.168.50.20/api/hamsters and attach the JWT in the Authorization header. You should get a successful response.

Troubleshooting

Check that the haproxy service is running:

sudo systemctl status haproxy

You can check if the haproxy.cfg file is valid with this command:

sudo haproxy -c -f /etc/haproxy/haproxy.cfg

Debug the incoming requests with:

sudo haproxy -d -f /etc/haproxy/haproxy.cfg

SSH into the VM with vagrant ssh and and make sure the node.js website is running:

cd /vagrant/web
docker-compose build
sudo docker-compose up -d
