Question

A developer writes a manifest file to create a Deployment and runs 'kubectl apply -f deploy.yaml'. The command returns the error: 'error: resource mapping not found ... no matches for kind "Deployment" in version "v1"'. The file begins with 'apiVersion: v1' and 'kind: Deployment'. What change should the developer make to fix this manifest?

Accepted Answer

Change the apiVersion to 'apps/v1' because Deployments belong to the apps API group

Answer

Change the kind to 'Pod' since Deployments are not a valid resource type in Kubernetes

Answer

Remove the apiVersion field entirely so the API server can infer the correct version

Answer

Add a 'namespace: v1' field to the metadata section to resolve the version mapping
