MiniKube

Follow these instructions to prepare minikube for Casskop installation with sufficient resources to run Casskop and some basic applications.

Prerequisites#

  • Administrative privileges are required to run minikube.

Installation steps#

  1. Install the latest version of minikube, version 1.1.1 or later, and a minikube hypervisor driver.

  2. If you’re not using the default driver, set your minikube hypervisor driver. For example, if you installed the KVM hypervisor, set the vm-driver within the minikube configuration using the following command:

    minikube config set vm-driver kvm2

  3. Start minikube with 16384 MB of memory and 4 CPUs. This example uses Kubernetes version 1.14.2. You can change the version to any Kubernetes version supported by Casskop by altering the --kubernetes-version value:

    $ minikube start --memory=16384 --cpus=4 --kubernetes-version=v1.14.2

Depending on the hypervisor you use and the platform on which the hypervisor is run, minimum memory requirements vary. 16384 MB is sufficent to run Casskop.

tip

If you don’t have enough RAM allocated to the minikube virtual machine, the following errors could occur:

  • Image pull failures
  • Healthcheck timeout failures
  • Kubectl failures on the host
  • General network instability of the virtual machine and the host
  • Complete lock-up of the virtual machine
  • Host NMI watchdog reboots
  • One effective way to monitor memory usage in minikube:
minikube ssh
