kubernetes - Calling an external service from within Minikube

Question

I have a service (/deployment/pod) running in my Minikube (installed on my Mac) that needs to call an external http service that runs directly on my Mac (i.e. outside Minikube). The domain name of that external service is defined into my Mac /etc/hosts file. Yet, my service within Minikube cannot call that external service. Any idea what I need to configure where? Many thanks. C

Answer 1

Create Endpoints that will forward traffic to your desire external IP address (your local machine). You can directly connect using Endpoints but according to Goole Cloud best practice (doc) is to access it through a Service

Create your Endpoints

kind: Endpoints
apiVersion: v1
metadata:
 name: local-ip
subsets:
 - addresses:
     - ip: 10.240.0.4  # IP of your desire end point
   ports:
     - port: 27017     # Port that you want to access

Then create you Service

kind: Service
apiVersion: v1
metadata:
 name: local-ip
Spec:
 type: ClusterIP
 ports:
 - port: 27017
   targetPort: 27017

Now you can call external http service using the Service name. In this case loal-ip like any other internal service of minikube.
