When you run a Pod in Kubernetes, by default, it expect it to be a long running service. But in your case, you run a one-off command that terminates immediately. To run one-off commands in Kubernetes, it is easiest to run them as Kubernetes Jobs.
First problem is to have a container ready for executing kubectl.
Since you are using Tekton, have a look at the "deploy task" from Tekton Hub, it is configured with an image that includes kubectl
