Kubernetes Minikube - Invalid memory value assigned for 'minikube'

3/9/2020

Setting up Minikube on my Windows 10 Surface laptop and the cluster fails to create. Performed the following steps:

  • Installed all Hyper-V features
  • Created Hyper-V external switch
  • Installed Minikube using choco install minikube
  • Configured minikube using minikube config --driver=hyperv
  • Attempted to start minikube using minikube start --hyperv-virtual-switch=ExternalWifi

When attempting to start, minikube throws the following error:

PS C:\WINDOWS\system32> minikube start --driver=hyperv

When attempting to manually create a VM using the same parameters that the minikube setup was attempting to use, I discovered that Hyper-V requires you to assign memory in 2 MB increments. Minikube was attempting to create a VM with 4077 MB of memory which was causing the failure. When I ran minikube setup with the command below, initialization completed successfully:

minikube start --driver=hyperv --memory=4078m
