Summary

Amazon Linux is a Redhat&CentOS-like OS
yum, rpm available
MiniKube requires at least 2 logical processors
Kind can be used to install Kubernetes Cluster on 1 vcpu LightSail but the performance is poor

Notes

Recently I have a need to test some Kubernetes use cases. So I deployed a minikube on an Amazon LightSail instance (I thought kubeadm/kops is better, but for the sake efficiency, just do it quickly and try them later would be better) . The instance is Amazon Linux 2(IDK what it's differet from one).

So I went to check os-relase to know what environment is actually.

And a few quick tests showed yum & rpm is available.

Install Minikube and failed to run

Then install docker, minikube according to Minikube instruction.

Then start docker service and start minikube service. But the attempt of initiating MiniKube failed due to the insufficient CPUs.

So I can use 4 logical processors on my laptop but here I can only use 1...😦

Install Kind and not feasible to use

And I switched to use another cluster implement kind. However, after I installed it, the performance of running sudo-level commands becomes really poor.

By now IDK exactly the reason contributing to this poor performance. Since it only happens after I started kind service, a high chance that the reason is it. Or another reason can be, the credits of lightsail are all consumed.
