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.

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: ...
