Lab 2.3 create a basic pod - cannot connect to pod via CLUSTER IP
So I am using Ubuntu 20.04, not 18.04. Everything working great but for lab 2.3, step 11, if I try to access to the web server using the CLUSTER-IP for the basicservice, I get a connection time out:
curl: (7) Failed to connect to 10.99.248.201 port 80: Connection refused
Now if I try to hit the pod directly by its IP, I get expected result.
ubuntu@my-master-node:~$ kubectl get svc NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE basicservice NodePort 10.99.248.201 <none> 80:32489/TCP 2m58s kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 29m ubuntu@my-master-node:~$ curl http://10.99.248.201 curl: (7) Failed to connect to 10.99.248.201 port 80: Connection refused ubuntu@my-master-node:~$ kubectl get pod -o wide NAME READY STATUS RESTARTS AGE IP NODE NOMINATED NODE READINESS GATES basicpod 1/1 Running 0 21s 192.168.208.194 ip-172-31-36-1 <none> <none> ubuntu@my-master-node:~$ curl http://192.168.208.194 <!DOCTYPE html> [...]

If you're using aws or gcp, make sure your security group & vpc nacl (aws)/firewall rule (gcp) isn't blocking the request to your cluster ip. I had this issue until I added a firewall rule to allow all traffic from all src ips. (0.0.0.0/0) Of course you can tighten these up but it's a quick way to see if that's the root cause.

Hi and thanks for your comment. I have checked all that and it's all open.

I'm not sure I understand what that IP is anyway? I understand hitting the POD through its IP (and it's running on the other node) and that';s working fine, but what's the basic service IP for ?

Never mind, I went through basic.yaml and basicservice.yaml and I got some lines wrong. All working now
