curl: (7) Failed to connect to 192.168.99.100 port 31591: Connection refused

Question

These are my pods

hello-kubernetes-5569fb7d8f-4rkhs   0/1     ImagePullBackOff   0          5d2h
hello-minikube-5857d96c67-44kfg     1/1     Running            1          5d2h
hello-minikube2                     1/1     Running            0          3m24s
hello-minikube2-74654c8f6f-trrrw    1/1     Running            0          4m8s
hello-newkubernetes                 0/1     ImagePullBackOff   0          5d1h

If I try

curl $(minikube service hello-minikube2 --url)
curl: (7) Failed to connect to 192.168.99.100 port 31591: Connection refused

Let's check VBox

inet 192.168.99.1/24 brd 192.168.99.255 scope global vboxnet0
   valid_lft forever preferred_lft forever
inet6 fe80::800:27ff:fe00:0/64 scope link 
   valid_lft forever preferred_lft forever

Why is my connection refused?

tomcat-deployment   172.17.0.6:8080                   11h

I want to show service endpoint

minikube service tomcat-deployment --url
http://192.168.99.100:30613

Why is this url different from get ep -o wide output?

Answer 1

Apparently, you are trying to reach your service outside of the cluster, thus you need to expose your service IP for external connection.

Run kubectl edit svc hello-minikube2 and change

type: NodePort

to

type: LoadBalancer

Or

kubectl expose deployment hello-minikube2 --type=LoadBalancer --port=8080

On cloud providers that support load balancers, an external IP address would be provisioned to access the Service. On Minikube, the LoadBalancer type makes the Service accessible through the minikube service command.

Run the following command:

minikube service hello-minikube2
