Original Helm chart gone - how can I find / get it from the cluster? I'm connected to a cluster which has a release, from a chart, but it was installed by someone else who I think used a tweaked, locally-stored chart.

I don't have access to their original chart/repo. Is there a way I can retrieve it from the cluster, so I can tweak/amend, and re-install it?

Or, can I find the URL of the original repo that was used? The chart name is wordpress-0.6.0, but that's of no use, since it's the same as the "official"/original one.
You can use helm get manifest &lt;RELEASE_NAME&gt; to fetch the kubernets manifests and you can use helm get values &lt;RELEASE_NAME&gt; to get the values.yaml from the cluster. But I don't think there is any way to get the chart files back. Sorry.

PS: Please replace &lt;RELEASE_NAME&gt; with your release name.
