Minikube expose MySQL running on localhost as service

Question

I have minikube version v0.17.1 running on my machine. I want to simulate the environment I will have in AWS, where my MySQL instance will be outside of my Kubernetes cluste

Answer 1

Kubernetes allows you to create a service without selector, and cluster will not create related endpoint for this service, this feature is usually used to proxy a legacy component or an outside component.

1. Create a service without selector

   apiVersion: v1
   kind: Service
   metadata:
       name: my-service
   spec:
       ports:
           - protocol: TCP
             port: 1443
             targetPort: 
   

2. Create a relative Endpoint object

   apiVersion: v1
   kind: Endpoints
   metadata:
       name: my-service
   subsets:
       - addresses:
           - ip: 
         ports:
           - port: 
   

3. Get service IP

   $ kubectl get svc my-service
   NAME         CLUSTER-IP     EXTERNAL-IP   PORT(S)   AGE
   my-service              1443/TCP    18m
   

4. Access your MYSQL from service :1443 or my-service:1443
