When running the helm install command given in the dashboard...

Release "kubecost-cloud" does not exist. Installing it now.

@AjayTripathy @mbolt35 do you know how we are handling this? I believe hostnetwork access is required for this pod.

@nikhiljha are you able to confirm everything deployed as expected without network-costs enabled?

[AjayTripathy]

I can confirm hostnetwork access is required for network costs. It's currently a hard requirement though we can take this into consideration for future releases.

Note that you can still view network costs in GKE autopilot with GKE cost report integration; we just won't be able to break it down precisely on a per-pod basis. Instead, each pod gets a cost-weighted share of the node's network price based on the node it's running on

[nikhiljha]

I wanted something like kubectl cost that would show me a list of pods and the $/hr they cost (which should be fairly simple for autopilot) but it doesn't look like kubecost can do this so I gave up :(

[AjayTripathy]

Hi @nikhiljha it's surprising that this doesn't work out of the box. Can you share the exact helm install command you used?

[AjayTripathy]

Also, you can try to run the helm command with
--set networkCosts.enable=true
