HelmRelease not ready and HelmChart downloads

[avthart]

We have deployed e.g. cert-manager (v1.1.0) using a HelmRelease. Deployed and running successfully.

After a while, the HelmChart could not be downloaded because of an (temporary) HTTP 503 error. This currently leads to a not ready status for the HelmRelease, even when there 's no change (not an updated/newer version) for that HelmRelease.

Is this what we want and expected behaviour? It looks like HelmCharts will be downloaded even when that version is already downloaded before.

Yes, since chart versions are not guaranteed to be immutable, we download them every time.

PS. You can control the interval at which source-controller tries to download the chart with HelmRelease.spec.chart.spec.interval, more details here https://toolkit.fluxcd.io/components/helm/helmreleases/
