How do I sniff traffic from the localhost to my k8s cluster (running locally)?

unknown field "capabilities" in io.k8s.api.core.v1.PodSecurityContext (running tshark in a container/k8s pod)

QUESTION

How do I sniff traffic from the localhost to my k8s cluster (running locally)?

Asked 2021-Mar-14 at 09:39

I have a minikube cluster running locally and a pod, cluster ip 172.17.0.8.

I am using ksniff to sniff traffic on that pod.

In the pod when I ping www.google.com. I can see, in the wireshark capture, ICMP request going to/from:

pod (172.17.0.8) <--> google server (some IP)

I know there is an intermediate step. Where my macbook (the cluster host) is making the request on behalf of the pod and receiving the response to send to the correct pod.

pod (172.17.0.8) <--> cluster host (macbook) <--> google server (some IP)

How can I capture the traffic between the pod and the cluster host (eg. macbook)?

I haven't used minikube nor a macbook so your mileage may vary, but let's try figuring this out.

From what I've seen, pods are typically provided with a default gateway by the host. In other words, the host serves as a router for the pods it hosts. How do we know that? When running an Ubuntu image on a K8s cluster (and installing iproute2), I get the following routing table:

I have build a docker image containing tshark (its an image I am going to use for doing various manual debugging from a kubernetes pod).

I have deployed a container in kubernetes running that image. But when I access the container and try to run tshark I get:

Looking specifically to the error, you posted only part of your manifest and looking to this we can see that you put securityContext: in the same level as containers::
