minikube kubernetes – how to access specific pod IP endpoint using curl

This tutorial assumers that minikube kubernetes is already installed. Steps to access pod IP endpoint using curl

1. Instal minikube and kubernetes
2. create multi replica deployment
3. Find pod IPs
   kubectl get pods -l app=hello-minikube -o yaml | grep podIP
   

       podIP: 10.244.0.3
       podIPs:
       podIP: 10.244.1.6
       podIPs:
       podIP: 10.244.1.5
       podIPs:

4. Ssh to minikube VM (one of the nodes)
   minikube ssh
5. Run curl to access podIP:port
   curl POD_IP_ONE_OF_THE_ABOVE_LIST:8080
curl 10.244.0.3:8080
   

   Request served by hello-minikube-7ddcbc9b8b-nmc2c
   
   HTTP/1.1 GET /
   
   Host: 10.244.0.3:8080
   Accept: */*
   User-Agent: curl/7.68.0

6. Another alternative is to use proxy (ssh not needed in this case)
   kubectl port-forward hello-minikube-7ddcbc9b8b-nmc2c 8080
curl localhost:8080
7. To get podName for above command
   kubectl get pods -l app=hello-minikube
