kustomize build changing string values to integer

[sahil-sawhney]

I have one of my yaml in overlays to include environment variables as follows
COUNT: "10"
Now when I do a Kustomize build, above content transforms to this
COUNT: 10
Now when I try to do a kubectl apply to this, it reports an error
The pod is invalid: spec.containers.env.COUNT: Invalid value: "integer": spec.containers.env.COUNT in body must be of type string: "integer"

Please provide your kustomization.yaml file and other related files so we can reproduce it.

@Shell32-Natsu I got my issue resolved. It was a problem caused by envsubst. Thanks for checking

@sahil-sawhney We're seeing this issue on Ubuntu 20.04.1 LTS where integers in environment variables were quoted in kustomization.yaml but not quoted in the generated manifests after running kustomize. What did you do to resolve this issue with envsubst? Thanks!
