Kubernetes deployment Error: unknown flag: --replicas issue

Question

While creating a deployment using command

kubectl create deploy nginx --image=nginx:1.7.8 --replicas=2 --port=80

I am getting error Error: unknown flag: --replicas

controlplane $ kubectl version
Client Version: version.Info{Major:"1", Minor:"18", GitVersion:"v1.18.0", GitCommit:"9e991415386e4cf155a24b1da15becaa390438d8", GitTreeState:"clean", BuildDate:"2020-03-25T14:58:59Z", GoVersion:"go1.13.8", Compiler:"gc", Platform:"linux/amd64"}

controlplane $ kubectl create deploy nginx --image=nginx:1.7.8 --replicas=2 --port=80
Error: unknown flag: --replicas
See 'kubectl create deployment --help' for usage.

Could anyone please help me with the reason for this as this command is working on other Kubernetes clusters?

Answer 1

You may try to put a blank character between -- and the commands For example

kubectl create deploy nginx --image=nginx:1.7.8 -- replicas=2

It's work for me.
