I have an existing Deployment which has an image in the spec. I have changed it to only run single pod to do some test work, Now I want to run a test app within that pod which is in a zip.
Is it possible to run this app by directly copying it into the pod? Or is it required to build it as an image and update the Deployment?
It is possible to do a lot of things, but many tricks are one-offs that lack mechanical sympathy with the automation, so are a misuse of the infrastructure and your operator attention. Best just to build an image and update the Deployment.
