Kubectl Common Commands

kubectl-common-commands

# See which clusters you have configured to connect to
kubectl config get-clusters

# Get info on the default cluster
kubectl cluster-info

# Get detailed info on the default cluster
kubectl cluster-info dump

# Some debugging commands
# Get list of events raised in a specific namespace ("data-layer" in this example)
kubectl get events -n data-layer

# Get the logs from a pod
kubectl logs my-pod-1ac3ex56g32

# Deleting Pods
# You don't actually delete pods, you delete deployments as we'll
# see below. Or you can edit the deployment to lower the replicas
# number which will remove pods.
#
# There are two ways to do this:
# 1. Delete the deployment directly in K8s
# 2. Delete using the original YAML

# Delete the deployment directly in K8s
kubectl delete deployment nginx-depl

# Delete using the original YAML
kubectl delete -f nginx-deployment.yaml
