I am using below command to create my pod
kubectl run pingpong --image alpine ping 1.1.1.1
This command works good, but doesn't create replicaset.
How can I create a replicaset with this command too? I tried below
kubectl create deployment pingpong --image alpine ping 1.1.1.1
but it doesn't work.
From kubernetes version 1.18 kubectl run
does not create deployment anymore because all the generators were deprecated.
You should use below command to create a deployment which internally creates a replicaset.
kubectl create deployment pingpong --image=alpine
Please note you can not pass a command like ping 1.1.1.1
in the above command.
If you want to add a command you need to edit the deployment created above using kubectl edit deployment pingpong
or use a yaml to create it in first place.
apiVersion: apps/v1
kind: Deployment
metadata:
name: alpine-deployment
spec:
replicas: 1
selector:
matchLabels:
app: alpine
template:
metadata:
labels:
app: alpine
spec:
containers:
- name: alpine
image: alpline
command: ["<Your command here>"]
Well if you are on the kubernetes version above 1.18 then the first command only create pod.
So if you want to create pod,deployment and replicaset
use this command
kubectl create deployment pingpong --image=alpine
and to list above created command objects use kubectl get pod,rs,deploy
