Create a pod from CLI

kubectl run nginx --image=nginx

Describe the pod details

kubectl describe pod <name>

Get pods listed with more details e.g. which nodes are running

kubectl get pods -o wide

Open a vim editor to edit the pod yaml definition file

kubeclt edit pod <podname>

Create/Reconfigure a pod based on a manifest file

kubectl apply -f manifest.yaml

Display the contents of a running pod yaml file

kubectl get pod <pod-name> -o yaml

Create a definition file from an existing one

kubectl get pod <pod-name> -o yaml > pod-definition.yaml

Creating objects imperatively

kubectl run nginx --image=nginx

With Labels

kubectl run redis --image=redis:alpine -l tier=db

Create a service

kubectl expose pod redis --port 6370 --name redis-service -l tier=db


kubectl create deployment webapp --image=kodekloud/webapp-color

Scale deployement

kubectl scale deployment/webapp --replicas=3

Create a pod and expose a port

kubectl run custom-nginx --image=nginx --port=8080

Create a namespace

kubectl create ns <name>

Pipe deployment to YAML file

kubectl create deployment redis-deploy --namespace=dev-ns --image redis --dry-run=client -o yaml > deploy.yaml

Replica Sets

kubectl get replicasets

use the same commands as pod for describe, edit, delete and also apply manifests


kubectl create -f deployment.yml

a deployment automatically creates a replicaset

to see all objects running in the cluster write

kubectl get all

Output format

the kubectl output can be specified with the -o argument other than receiving text only


-o json

Just the name

-o name

text with a few extra detail

kubectl get pods --namespace <namespace name>

Change namespace context to list resources on the set namespace

kubectl config set-context $(kubectl config current-context) --namespace=dev
