Running a kubernetes cluster on one google cloud instance

General Discussions

I would like to run a kubernetes cluster on one single Google Cloud instance.

I would like to have one front end pod and one back end pod.

I would like to run an nginx ingress controller on that cluster. The application, that I want to start with helm and a yaml-file, needs access to a mongoDB (Can I run this DB within the kubernetes cluster?).

I installed kubernetes and helm (see command lines below). They seam to work.
** But I can not find any instruction, what to do next.**

Do I also need Minikube, because I want to run the cluster on one single host/machine? It seams to me, that with an installation of Minikube Kubernetes is installed once again.

Cluster information:

Kubernetes version: kubectl version --client
Client Version: v1.32.3
Kustomize Version: v5.5.0
Cloud being used: (put bare-metal if not on a public cloud) google
Installation method: sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl
$ curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3
$ chmod 700 get_helm.sh
$ ./get_helm.sh

Host OS: Debian 12 bookworm
CNI and version: ??
CRI and version: ??

With the command line “kubectl version” I get
The connection to the server localhost:8080 was refused - did you specify the right host or port?

The error message suggests to me that you haven’t configured kubectl to point to your Kubernetes cluster.

The general tone of your message suggests that you only installed the command-line tools, kubectl and helm, on your local machine, and that you haven’t created your cluster yet.

It would be easier to just offload that task to Google and create a GKE cluster.
