Working Helm Configuration on AMD64

[paulhanssen]

Hi,

I've successfully installed Pulse in a VM on a Raspberry Pi 4B ARM64 instance. It works great (and is great)... thanks!

I'd now like to try putting in into a k3s cluster I've built, mostly to get some memory back.

The only helm command line I've gotten to run is this:

helm upgrade --install pulse  oci://ghcr.io/rcourtman/pulse-chart/pulse:4.24.0-rc.3  --values pulse-values.yaml --namespace pulse  --create-namespace

From there it appears to install

Release "pulse" does not exist. Installing it now.
Pulled: ghcr.io/rcourtman/pulse-chart/pulse:4.24.0-rc.3
...
NAME: pulse
LAST DEPLOYED: Wed Nov 12 12:37:17 2025
NAMESPACE: pulse
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
...

Unfortunately, the pod is stuck in the ImagePullBackOff state, which means (my understanding is that) it can't find the image.

Do you have a known working version number &/or command line for Pulse on AMD64? Cheers!

Helm reports the upgrade as successful because the manifests apply, but Kubernetes then tries to start the pod and gets ImagePullBackOff once the image download fails.

The chart defaults to repository rcourtman/pulse and assumes the tag is exactly 4.24.0-rc.3. That bare tag was never pushed for this RC. Only the tag named v4.24.0-rc.3 exists, so every pull fails even though Helm finished cleanly.

Two options unblock the cluster. Either rerun the install with --set image.tag=v4.24.0-rc.3 so the Deployment points at the tag that actually exists, or move to 4.28.0 or anything newer where both tag flavors are published and the default chart values work as-is.

Those Pulse images are multi architecture and already contain AMD64 and ARM64 layers, so the same fix works for Raspberry Pi nodes and standard x86 nodes.

Thank you so much @rcourtman, I was able to get it installed (Kubernetes, ARM64) with the following Helm command:

$ helm upgrade --install pulse  oci://ghcr.io/rcourtman/pulse-chart/pulse:4.29.0  --values pulse-values.yaml --namespace pulse  --set image.tag=v4.31.0  --create-namespace
