GitHub - sysdiglabs/kubectl-dig: Deep kubernetes visibility from the kubectl

kubectl dig

Deep kubernetes visibility from the kubectl.

kubectl dig A simple, intuitive, and fully customizable UI to dig into your kubernetes clusters

Install

go get -u github.com/sysdiglabs/kubectl-dig/cmd/kubectl-dig

Usage

Just dig

There's only one thing to do, provide the node name!

You just identify the node you want to dig in with kubectl get nodes and then provide it to the dig command!

kubectl dig ip-180-12-0-152.ec2.internal

dig + cluster metadata

By default, kubectl dig shows only information about the local node, if you want to dig from that node to the whole cluster you have to provide a service account that can read resources.

You can create a dig-viewer service account with:

kubectl apply -f https://github.com/sysdiglabs/kubectl-dig/raw/develop/docs/setup/read-serviceaccount.yml

Then you just use it with kubectl dig.

kubectl dig --serviceaccount dig-viewer 127.0.0.1

At this point you have access to the fancy cluster metadata, press F2 and look for the K8s views!
