Hey. Just started learning Kubernetes with a starter cluster with 1 vCPUs (12$/m option).
I’m trying to get my own project running on the k8s cluster with this guide: https://www.digitalocean.com/community/tutorials/how-to-set-up-an-nginx-ingress-on-digitalocean-kubernetes-using-helm
The nginx-ingress controller installed with helm should just be one command. But the status of the pod stays on “Pending” and when I describe the pod it says: 0/1 nodes are available: 1 Insufficient cpu. preemption: 0/1 nodes are available: 1 No preemption victims found for incoming pod.
Also somewhere in the describe: Requests: cpu: 100m memory: 90Mi Liveness: http-get http://:10254/healthz delay=10s timeout=1s period=10s #success=1 #failure=5 Readiness: http-get http://:10254/healthz delay=10s timeout=1s period=10s #success=1 #failure=3
Although I started with the cheapest kubernetes solution, it still should be enough I’d think.
Could someone help me or push me in a direction?

Apparently you need 2 nodes.
I can confirm that before the DO upgrade, 1 node was sufficient. Now only when upgrading to 2 nodes, it started working again.
Any idea why this is the case? I asked GPT and it says that this has to do with resource availability. Some control plane ops happen on the workers and if there’s not enough resources the ingress remains pending. I don’t know about that. I use a 4GB worker.
