Deploy Prometheus + Grafana Helm Chart

[Iril]

Trying to build this on 1 x Pi4 and 3 x Pi3 to further work with kubectl and clusters.
On deploy to the main node ( the Pi4 ) the ansible fails with this error.

Just wondered if anyone has seen this before and has any ideas.
The 4 Pis are all installed with the following Rasbian release. Running over wifi.

They have a hostname set that is the same as the inventory file.
Any hints appreciated.

Hey, had this myself. Found the issue is with that Helm version in /tasks/kubernetes/helm.yml

Change the version from 3.8.0 to the next suitable version for yourself, I used latest being 3.16.2.
