The provided example is docker-based so that you can deploy and test it very
quickly. First clone the repo make sure you don't have anything listening on
port 8080 before starting.
Add the following lines to your /etc/hosts to simulate multiple subdomains
127.0.0.1 secret.test.local
127.0.0.1 secret1.test.local
127.0.0.1 secret2.test.local
127.0.0.1 auth.test.local
Then, type the following command to build and deploy the services:
docker-compose build
docker-compose up -d
After few seconds the services should be running and you should be able to visit
[https://localhost:8080/](https://localhost:8080/).
[https://localhost:8080/](https://secret.test.local:8080/).
Normally, a self-signed certificate exception should appear, it has to be
