I’m an administrator of several clusters, and I’ve deployed a couple of catalogs such as https://charts.bitnami.com/bitnami and deployed a few apps from them.
Is it possible to see these apps using vanilla helm? I’d like to see the output of things like helm get values app, but I cannot get this to work.
If I use helm to list apps, I do not see anything:
$ helm ls --all-namespaces --all
NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
$
However, I can see various apps using the rancher CLI:
$ rancher apps
ID NAME STATE CATALOG TEMPLATE VERSION
p-abcd:cluster-alerting cluster-alerting active system-library rancher-monitoring 0.1.0
p-abcd:cluster-monitoring cluster-monitoring active system-library rancher-monitoring 0.1.0
$
Yes, it can … but in my case, I couldn’t see my ranchers apps using helm ls because the app was installed using helm 2.0 (rancher-helm) instead of helm3.
Once using helm 3.0 to install the rancher app, it works.

Ah, that explains it. I have the same app deployed in two clusters, and I can see it in one place but not in the other:
$ helm --kubeconfig cluster1.yml list --all-namespaces
NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
external-dns external-dns 15 2020-05-12 01:06:45.913700939 +0000 UTC deployedexternal-dns-3.0.0 0.7.0
$ helm --kubeconfig cluster2.yml list --all-namespaces
NAME NAMESPACE REVISION UPDATED STATUS CHART APP VERSION
$
If I view the metadata in cluster2, I certainly see that it references Helm v2 things such as “Tiller”.
Also, it appears that the Rancher Catalog in question is actually Helm v2, not Helm v3.
Unfortunately, I don’t see a way to upgrade the catalog itself. I assume we just remove the catalog and then reinstall it and it will be Helm v3.
