just setup a 3 node cluster on gke and attempted to use kubectl run to deploy a container.

I get

error: failed to discover supported resources: unable to retrieve the complete list of server APIs: metrics.k8s.io/v1beta1: an error on the server ("service unavailable") has prevented the request from succeeding

The error suggests that the cluster might be in an upgrading state.

For that, you can use the Google SDK and determine if it's being upgraded:

gcloud container clusters describe CLUSTER_NAME --zone ZONE/--region REGION

If not, check that you're actually pointing your kubectl tool to correct cluster:

kubectl config current-context

gcloud has the advantage that it can automatically configure your kubectl client:

gcloud container clusters get-credentials CLUSTER_NAME --zone ZONE/--region REGION

If the cluster is being in that state for quite a long time (usually several hours), there might be an error in the cluster backend (since GKE is a managed implementation of Kubernetes). If that's the case, you might want to reach out to support to review your case.
