How to run an older Kubernetes version with minikube ?

You do not need to download an older minikube to run an older kubernetes version. You can create a Kubenretes cluster with any version you desire using --kubernetes-version flag.


  1. minikube start --kubernetes-version=v1.15.0

Docker Driver: How to set the cgroup manager minikube uses?

By default minikube uses the cgroupfs cgroup manager for the Kubernetes clusters, if you are on a system with a systemd cgroup manager, this could cause conflicts. To use systemd cgroup manager, run:

  1. minikube start --force-systemd=true

How to run minikube with Docker driver if existing cluster is VM?

If you have an existing cluster with a VM driver (virtualbox, hyperkit, KVM,…).

First please ensure your Docker service is running and then you need to either delete the existing cluster and create one

  1. minikube delete
  2. minikube start --driver=docker

Alternatively, if you want to keep your existing cluster you can create a second cluster with a different profile name. (example p1)

  1. minikube start -p p1 --driver=docker

Does minikube support IPv6?

minikube currently doesn’t support IPv6. However, it is on the roadmap.

How can I prevent password prompts on Linux?

The easiest approach is to use the docker driver, as the backend service always runs as root.

none users may want to try CHANGE_MINIKUBE_NONE_USER=true, where kubectl and such will still work: see environment variables

Alternatively, configure sudo to never prompt for the commands issued by minikube.

How to ignore system verification?

minikube’s bootstrapper, Kubeadm verifies a list of features on the host system before installing Kubernetes. in case you get this error, and you still want to try minikube anyways despite your system’s limitation you can skip the verification by starting minikube with this extra option:

  1. minikube start --extra-config kubeadm.ignore-preflight-errors=SystemVerification

what is the resource allocation for Knative Setup using minikube?

Please allocate sufficient resources for Knative setup using minikube, especially when you run a minikube cluster on your local machine. We recommend allocating at least 6 CPUs and 8G memory.

  1. minikube start --cpus 6--memory 8000

Do I need to install kubectl locally?

No, minikube comes with built-in kubectl see minikube’s kubectl documentation.
