From 92ed439d2252146220922bc1dd8cacfc4090a8c5 Mon Sep 17 00:00:00 2001 From: Urvashi Mohnani Date: Tue, 12 Oct 2021 16:02:47 -0400 Subject: Don't add image entrypoint to the generate kube yaml If no entrypoint or command is set in the podman create command, and the image command or entrypoint is being used as the default, then do not add the image command or entrypoint to the generated kube yaml. Kubernetes knows to default to the image command and/or entrypoint settings when not defined in the kube yaml. Add and modify tests for this case.
