Please help. I am trying to deploy a web API to Azure ACS Kubernetes cluster, it is a simple web API created in VSTS and the result should be like this: { "value1", "value2" }
.
I plan to make the type as Cluster-IP but I want to test and access it first that is why this is LoadBalancer
, the pods is running and no restart (I think it's good).
The guide I'm following is: Running Web API using Docker and Kubernetes
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes ClusterIP 10.0.0.1 <none> 443/TCP 3d
sampleapi-service LoadBalancer 10.0.238.155 102.51.223.6 80:31676/TCP 1h
When I tried to browse the IP 102.51.223.6/api/values
it says:

It seems like to me that your service isn't set to a port on the container. You have your targetPort
commented out. So the service is reachable on port 80 but the service doesn't know to target the pod on that port.
