Clear helm cache from rancher

Catalog Refresh failing to pickup changes made to Charts

I recently upgraded to Rancher v2.2.2 so that I can use the added valuesYaml parameter in the payload for deployment requests of Catalog Apps via Rancher’s Rest API. I have made changes to helm charts stored in our Custom Catalog (Helm Repo) and then run a refreshCatalog for Rancher via the UI. The helm charts fail to update and still show the older versions. Our helm repo is in Amazon S3. I can see from S3 that the charts have been successfully updated so i suspect that the issue lies within …

Rancher caches helm charts based on their version. If the chart version doesn’t change, rancher assumes the chart hasn’t changed. There is no guarantee that a forceRefresh will update your chart in rancher if it has the same chart version. I describe a workaround to this issue in the provided post. Hope it helps!
