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.
Apparently I was able to create ingres in cluster with only one node. I tried prod with 2 nodes and it worked fine. Then I made a new env for dev using only one node. That one worked as well. I used Basic, Regular SSD, 4GB Ubuntu 22.04 nodes. They are a bit pricier but it’s already needed for me. So maybe that makes a difference when starting ingress on one node.
