@mjasion, would it be possible to use relative paths for all the hardcoded URLs that use the template above? E.g.

https://github.com/iterative/helm-charts/blob/b6439033a5c784db305b5afa77b421355d3fa186/charts/studio/templates/configmap-studio.yaml#L12

- {{include "ingress.protocol" . }}://{{.Values.global.host }}{{- if and .Values.global.basePath (not (eq .Values.global.basePath "/")) }}/{{ include "studio.basePath" . }}{{- end }}/api
+ /api

It's probably not viable for webhooks, but yes for API_URL and UI_URL among others.

@0x2b3bfa0 I think not now. We need to change the code of webapi and webui AFAIK.
