Kustomization resources are silently dropped if there is an extra space after `---`
Today I upgraded from FluxCD version v0.13.4
to version v0.15.3
and suddenly some of our HelmRepository
created (and owned) by a Kustomization
disappeared despite them still being part of that Kustomization
. After some analysis I figured out that actually all resources which had extra spaces (' '
) after the YAML ---
sequences where silently dropped without any warning or error in the logs. In the following example the linkerd2-edge
was silently dropped as it contained an extra space in ---
and linkerd-stable
was not dropped (as it contains no extra space after ---
).
---
apiVersion: source.toolkit.fluxcd.io/v1beta1
kind: HelmRepository
metadata:
name: linkerd2-edge
namespace: flux-system
spec:
interval: 10m
url: https://helm.linkerd.io/edge

I assume this is some kind of bug related to YAML parsing. Maybe this is another breaking change resulting from switching to Kustomize V4 (https://github.com/fluxcd/flux2/issues/1522) or go-yaml.
Yes, this is definitely related to fluxcd/flux2#1522 – thanks for the report
I'm going to look through sig-cli/kustomize for any open issues related to this report and try to link them back, so we can know when this is unblocked.
