Install Kubeflow locally

For local installation of Kubeflow you can use Vagrant box, Minikube or install it using Multipass. Here I will describe the multipass installation. The best link for the installation process is here . This installation uses Microk8s orchestrator and has some caveats. First of all you have to create volumes manually, other way you services won't work correctly. Before all I would suggest to install version 1.13 of microk8s, because 1.14 is not compatible now with kubflow. sudo snap install microk8s --channel=1.13 For this purpose please edit kubernetes-tools/setup-microk8s.sh line 10: CHANNEL=${CHANNEL:-1.13/stable} 1.14 where changed on 1.13.

The deployment will hook wrong image, so cluster won't build without the fix. Problem is in the naming of the image used to build rabbits. image: "${APPLICATION_NAME}:${RABBITMQ_VERSION}" Change to: image: ...
