ℹ️ OS release is Oracle Linux Server 8.3
🐳 Preparing Kubernetes v1.20.2 on Docker 20.10.5 ...
▪ Generating certificates and keys ...
▪ Booting up control plane ...
▪ Configuring RBAC rules ...
🤹 Configuring local host environment ...
❗ The 'none' driver is designed for experts who need to integrate with an existing VM
💡 Most users should use the newer 'docker' driver instead, which does not require root!
📘 For more information, see: https://minikube.sigs.k8s.io/docs/reference/drivers/none/
❗ kubectl and minikube configuration will be stored in /root
❗ To use kubectl or minikube commands as your own user, you may need to relocate them. For example, to overwrite your own settings, run:
▪ sudo mv /root/.kube /root/.minikube $HOME
▪ sudo chown -R $USER $HOME/.kube $HOME/.minikube
💡 This can also be done automatically by setting the env var CHANGE_MINIKUBE_NONE_USER=true
🔎 Verifying Kubernetes components...
▪ Using image gcr.io/k8s-minikube/storage-provisioner:v4
🌟 Enabled addons: default-storageclass, storage-provisioner
💡 kubectl not found. If you need it, try: 'minikube kubectl -- get pods -A'
🏄 Done! kubectl is now configured to use "minikube" cluster and "default" namespace by default
