Kubeflow

What is MiniKF?

• MiniKF is a virtual machine that is created by Arrikto.
• MiniKF = Minikube + Kubeflow + ROK (Rok: Data Management Platform on Kubernetes, developed by Arrikto)

Why should we use MiniKF?

• It is free and easy to use quickly for learning and developing Kubeflow pipelines in a one-virtual-machine.

How do we install MiniKF?

• Install Virtualbox 6.1.40 (stable with Vagrant and MiniKF)=> https://download.virtualbox.org/virtualbox/6.1.40/

• Install Vagrant => https://developer.hashicorp.com/vagrant/docs/installation

• What is Vagrant?

  • Vagrant is the command line utility for managing the lifecycle of virtual machines.

• On the powershell:

vagrant init arrikto/minikf
vagrant up

• On browser, open http://10.10.10.10/

  

  

  

• With Kubectl on the host PC, we can see the running Kubernetes Objects. Download "kubectl" application, add the path of "kubectl" in the environment variables.

• Download kubeconfig file as described below, hence it is possible to see the Kubernetes objects (pods, deployments, etc.)

  

• Run commands on the powershell on the host PC:

kubectl -n kubeflow get pods

• Connect to the VM to see Kubeflow UI

  

Troubleshooting

One of the pod is not ready (34/35 remaining)

• Delete the pod that is 'CrashLoopBackOff', deleted service is restarted automatically.

kubectl delete pod notebook-controller-deployment-7c46fdd957-87zfw -n kubeflow

• Connect MiniKF with clicking button

  

Can't connect to MiniKF landing page on http://10.10.10.10 after installing MiniKF

• According to this post: https://stackoverflow.com/questions/60820998/cant-connect-to-minikf-landing-page-on-http-10-10-10-10-after-installing-mini

• Stop VM using VirtualBox GUI and run 'vagrant up' again, then http://10.10.10.10

Increasing 'config.vm.boot_timeout'

• According to this post: https://stackoverflow.com/questions/32731629/where-to-find-config-vm-boot-timeout

• Go to this file (VagrantFile), if your installation is default path: C:\HashiCorp\Vagrant\embedded\gems\2.3.4\gems\vagrant-2.3.4\Vagrantfile

• In the root directory of your Vagrant install, there's the Vagrantfile file. There, I added config.vm.boot_timeout = 600 just after Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|.

config.vm.boot_timeout = 600
