Error making the image in a raspberry pi

Hi,

I'm trying to make my own image of the random scheduler in a Raspberry Pi Kubernetes cluster, but when I use the command

docker build -t angel96eur/marton-randomscheduler .

I get this:

Where the error could be?

Not enough replicas when creating adeployment for the scheduler

Dear Marton,
first off, happy Holidays and Merry Christmas if you celebrate it!
I found your repository when trying to follow this guide on writing own kubernetes scheduler: https://banzaicloud.com/blog/k8s-custom-scheduler. Their links are broken, but I assume they mean your scheduler.
However, I have a problem and I don't know if this is my local issue or a problem with the scheduler. Whenever I create a deployment, it does not create a pod, because not enough replicas are available:

I have re-created the deployment, but to no avail. I get a feeling that there should already be one replica before the deployment gets started? If I create deployments with other apps, they start the pods and get executed successfully. I am using a minikube setup.
Have you or other people ever experienced this issue? Do you have any idea how it can be solved?
I am very sorry if this question is inappropriate or comes at a wrong time. I really don't want to pester you, but I don't have any people I can ask about kubernetes setup.
Thank you a thousand times in advance and have a great evening!
Yours,
Svetlana.
