I’m trying to run the command "oc apply -f basic-ocp-demo.yaml" in order to create services and deployment in my openshift, but I get an error regarding "unable to decode "basic-ocp-demo.yaml ": no kind "Deployment" is registered for version "v1beta1 "

My file look like :

apiVersion: v1
kind: Service
metadata:
  name: nginx-service
spec:
  type: NodePort
  selector:
    app: nginx-app
    type: front-end
  ports:
    - port: 80
      targetPort: 80
      nodePort: 30012
---
kind: Deployment
apiVersion: v1beta1 
metadata:
  name: nginx-deployment
  labels:
    app: nginx-app
    type: front-end
spec:
  replicas: 3
  selector:
    matchLabels:
      app: nginx-app
      type: front-end
  template:
    metadata:
      labels:
        app: nginx-app
        type: front-end
    spec:
      containers:
        - name: nginx-container
          image: nginx:latest

oc apply command output:

[root@localhost openshift]# oc apply -f basic-ocp-demo.yaml 
service "nginx-service" created
error: unable to decode "basic-ocp-demo.yaml": no kind "Deployment" is registered for version "v1beta1"

Seems that my service nginx was created but the Deployment kind has no registration for version "v1bet1", I tried to put many other version but the same problem:

I’ve tried with "apps/v1", the same issue:

error: unable to decode "basic-ocp-demo.yaml": no kind "Deployment" is registered for version "apps/v1"

I’ve made a curl where can be seen all the apis available but I don’t know what to choose from that list for my Deployment Kind.

Here is my apis list : https://92.42.107.195:8443/apis

  1. It would appear you are running an extremely old version of OpenShift/Kubernetes. So all you have available is apps/v1alpha1. You should upgrade ASAP.

  2. Please use the command oc api-resources to list all the resources and use the mentioned version API version from the list for the deployment.
