Kubernetes deployment failure due to invalid command syntax

Symptom

Kubernetes POD in "RunContainerError" status after deployment and constantly restarts after deletion

Error Message

Warning  Failed     16s (x3 over 36s)  kubelet, node01    Error: failed to start container "nginx": Error response from daemon: OCI runtime create failed: container_linux.go:345: starting container process caused "exec: \"generator=run-pod/v1\": stat generator=run-pod/v1: no such file or directory": unknown

Resolution

Locate the deployment for the created POD by running kubectl get deployments --all-namespaces

$ kubectl get deployments --all-namespaces
NAMESPACE     NAME      READY   UP-TO-DATE   AVAILABLE   AGE
default       nginx     0/1     1            0           6m7s

Delete the deployment that is failing by running kubectl delete -n NAMESPACE deployment DEPLOYMENT:

$ kubectl delete -n default deployment nginx
deployment.apps "nginx" deleted

Rerun the deployment by running kubectl run --image= --generator=run-pod/v1:

$ kubectl run nginx --image=nginx --generator=run-pod/v1
pod/nginx created
