(code provided) Minimal k8s aspire application generates invalid YAML assets: duplicate ports, invalid values, etc. #14029
Description
Is there an existing issue for this?
- I have searched the existing issues
Describe the bug
Use minimal aspire app created with aspire new and configured to be deployed to k8s provided here).
- Create a free tier AKCS cluster named
mi-k8s - Create container registry
aspireapp - Execute a simple BASH shell script in here which does
aspire deploy,helm pack .andhelm install
Note the following issues
-
.WithContainerRegistryin AppHost's code has no effect: the passed private registry is ignored, and instead images are pulled from docker.io which results in an image pull error. -
Note a number of errors pointing that YAML assets generated by aspire deploy are invalid:
