Describing Kubernetes resources

We can quickly take a look at the internals of this pod by running the kubectl describe command:

$ kubectl describe pod httpd-8576c89d7-qjd62
Name: httpd
Namespace: default
Node: minikube/192.168.99.101
Start Time: Sat, 10 Mar 2018 00:01:33 -0700
Annotations: <none>
Status: Running
IP: 172.17.0.4
...
<output omitted>
...

It gives us enough information to efficiently locate the pod and do the proper troubleshooting when necessary. In our case, we can ssh to Minikube VM and run the curl command to check if the pod is running the web server properly.

You may need to use another IP address for the curl command; in our case it is 172.17.0.4, derived from the kubectl describe command output.

$ minikube ssh
$
$ curl 172.17.0.4
<html><body><h1>It works!</h1></body></html>
$ exit

Note that this pod is accessible only inside the Kubernetes cluster. That is the reason why we need to log in to Minikube VM. If we try to access this address from our local PC, it will not work. We are going to discuss this in the following sections.
