Adding a Reverse Proxy to the Compose Environment
Explore setting up a reverse proxy with Nginx and fixing gRPC connections.
We can quickly set up a reverse proxy using Nginx, a popular web server, reverse proxy, and load balancer application. We only need to set up a reverse proxy today, and thankfully, it is going to be quite easy.
Configuring an Nginx reverse proxy for microservices
First, we define a configuration file for the application called
/docker/nginx.conf
:
worker_processes 1;events { worker_connections 1024; }http {sendfile on;upstream docker-baskets {server baskets:8080;}# ... plus upstream blocks for each other microserviceserver {listen 8080;location /api/baskets {proxy_pass http://docker-baskets;proxy_redirect off;}location /baskets-spec/ {proxy_pass http://docker-baskets;proxy_redirect off;}# ... plus location block pairs for each other microservice# then one more location block for the swagger-ui fileslocation / {proxy_pass http://docker-baskets;proxy_redirect off;}}
We have only included the baskets microservice as an example in the configuration file example, but each microservice would need to have an upstream configuration and a pair of location configurations so that the reverse proxy could properly redirect the requests to where they need to go. A final location block is used to serve the Swagger UI from any microservice.
Secondly, we need to remove the port configurations for each microservice and add the reverse proxy as a new service to the ... ...
