$ pgrep -a docker 

$ minikube stop;

$ minikube start --driver=docker --memory=2000mb

$ kubectl create deployment ubuntu-fun --image=ubuntu:latest -- /bin/bash -c "sleep infinity"

$ kubectl config view

$ kubectl get deployments 

$ kubectl get pods 

$ kubectl delete deployment ubuntu-deploy or 

$ kubectl scale deployment ubuntu-deploy --replicas=0 # to temporary stop pod 

$ kubectl scale deployment ubuntu-deploy --replicas=1 # to start pod 

kayyum@kayyum-virtual-machine:~$ minikube start --driver=docker --memory=2000mb

😄  minikube v1.37.0 on Ubuntu 22.04

✨  Using the docker driver based on existing profile

❗  You cannot change the memory size for an existing minikube cluster. Please first delete the cluster.

🧯  The requested memory allocation of 3072MiB does not leave room for system overhead (total system memory: 3868MiB). You may face stability issues.

💡  Suggestion: Start minikube with less memory allocated: 'minikube start --memory=3072mb'

👍  Starting "minikube" primary control-plane node in "minikube" cluster

🚜  Pulling base image v0.0.48 ...

🔄  Restarting existing docker container for "minikube" ...

🐳  Preparing Kubernetes v1.34.0 on Docker 28.4.0 ...

🔎  Verifying Kubernetes components...

    ▪ Using image gcr.io/k8s-minikube/storage-provisioner:v5

    ▪ Using image docker.io/kubernetesui/dashboard:v2.7.0

    ▪ Using image docker.io/kubernetesui/metrics-scraper:v1.0.8

💡  Some dashboard features require the metrics-server addon. To enable all features please run:

minikube addons enable metrics-server

🌟  Enabled addons: storage-provisioner, dashboard, default-storageclass

🏄  Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default
