在GCP Kubernetes（GKE）中，如何将部署创建的无状态Pod分配给预配置的vm

Question

I have several operational deployments on minikube locally and am trying to deploy them on GCP with kubernetes.

When I describe a pod created by a deployment (which created a replication set that spawned the pod):

kubectl get po redis-sentinel-2953931510-0ngjx -o yaml

It indicates it landed on one of the kubernetes vms.

I'm having trouble with deployments that work separately failing due to lack of resources eg cpu even though I provisioned a VM above the requirements. I suspect the cluster is placing the pods on it's own nodes and running out of resources.

How should I proceed?

Do I introduce a vm to be orchestrated by kubernetes? Do I enlarge the kubernetes nodes? Or something else all together?

Answer 1

It was a resource problem and node pool size was inhibiting the deployments.I was mistaken in trying to provide google compute instances and disks.

I ended up provisioning Kubernetes node pools with more cpu and disk space and solved it. I also added elasticity by provisioning autoscaling.

here is a node pool documentation

here is a terraform Kubernetes deployment
