What is Express-Gateway?

Express Gateway secures your microservices and exposes them through APIs using Node.js, ExpressJS and Express middleware. Developing microservices, orchestrating and managing them now can be done insanely fast all on one seamless platform without having to introduce additional infrastructure.
Express-Gateway’s documentation can be found at https://express-gateway.io/docs.

1. Link Express-Gateway to a Redis container
Start a Redis container by executing:
$ docker run -d --name express-gateway-data-store \ -p 6379:6379 \ redis:alpine
2. Start the Express-Gateway instance
Once the Redis instance has been started (if required), we can start the Express-Gateway instance link it to the Redis container.

Note: You might want to expose other ports to the host in case you’re serving your APIs through HTTPS.
Note: You need to mount a volume with configuration files and volumes in order to make Express-Gateway start correctly.
