operating k8s – misc notes

basics

#kubectl config get-clusters
kubectx

#kubectl get ns
#--context <cluster>
kubens -c

-o json
-o yaml

get into a specific container

e.g. when the sidecar is in your way…

kubectl get pods 
kubectl get pod POD_NAME_HERE -o jsonpath='{.spec.containers[*].name}'; echo

gives e.g.

exporter haproxy

so let’s get into the haproxy container

kubectl exec -ti POD_NAME_HERE -c haproxy -- /bin/bash
