Automatically ip(service name) in deployment?

Question

Devops

Hello,
I started getting acquainted with Kubernetes a little. I want to run a small DockerRegistry. At the same time, I want everything that needs to be started with one config.
When starting registry-frontend, you need to specify the address to the service / pod where DockerRegistry is running.
How can I specify in the configuration that the registry is available at the address of the registry service?
To run the config in one fell swoop.
Could not reach the service via dns. Although I try the same way as I write in the documentation.

[[email protected] tmp]# curl http://registry.tools.svc.cluster.local:5000
curl: (6) Could not resolve host: registry.tools.svc.cluster.local; Unknown error

Thanks for the hints. Here is the config, I want to automatically fill in the variable ENV_DOCKER_REGISTRY_HOST.

apiVersion: v1
kind: Service
metadata:
  name: registry
  labels:
    app: tools
spec:
  type: NodePort
  ports:
  - port: 5000 
    name: registry
    targetPort: 5000
    nodePort: 31111
  selector:
    app: tools

apiVersion: apps/v1

        env:
        - name: ENV_DOCKER_REGISTRY_HOST
          value: "10.233.75.18"
        - name: ENV_DOCKER_REGISTRY_PORT
          value: "5000"

Thanks for the tips!
