Navratan Lal Gupta:
You can not curl into cluster pods from outside the cluster whose service type is ClusterIP. You need to have service with node type as NodePort and curl into it with nodeIP and port.

#2

Deepak Mourya:
@Navratan Lal Gupta Hi, I am using this from inside the cluster and with the same node.

#3

Navratan Lal Gupta:
Can you send yaml deployed

#4

Navratan Lal Gupta:
k get svc nginx -o yaml

#5

Deepak Mourya:
copy whole yaml is not possible, may be describe svc and pod details are fine ?

#6

Deepak Mourya:
spec:
clusterIP: 10.102.94.17
clusterIPs:

  • 10.102.94.17
    ports:
  • port: 8080
    protocol: TCP
    targetPort: 8080
    selector:
    run: nginx
    sessionAffinity: None
    type: ClusterIP
    status:
    loadBalancer: {}

Navratan Lal Gupta:
svc looks good. Are you sure if nginx is running fine in pod

#8

Deepak Mourya:
yes it is running
root@controlplane:~# k get pods --show-labels
NAME READY STATUS RESTARTS AGE LABELS
nginx 1/1 Running 0 36m run=nginx

Vinay:
can you edit the Pod port to 8080 and try

    Port: 8080
#15

Deepak Mourya:
hmm ok

#16

Deepak Mourya:
How to set port in the pod ?

#17

Deepak Mourya:
It seems lab session out now :frowning:

#18

Hinodeya:
Its’normally because this ip adress 10.244.0.4:8080 is the ip of the pod

#19

Hinodeya:
You have to create another type of rule --type=NodePort in this case

#20

Hinodeya:
kubectl expose po “name of pod” --type=NodePort --port 8080 target-port 8080 --name svcpodexpose --dry-run -o yaml >svcpo.yaml
