Injected environment variables in Kubernetes pod

By default, when a service is created, Kubernetes injects some environment variables in pods within the same namespace. These variables follow the pattern:

SERVICE-NAME_VARIABLE-NAME

If you have a service named nginx-provider, that generates the following variables (non-exhaustive) then you can simply inject these environment variables into your application:

• NGINX_PROVIDER_SERVICE_HOST, which contains the IP address of the Service. For example, 10.0.0.11
• NGINX_PROVIDER_SERVICE_PORT, which contains the port where Service listens on. For example, 6379
