Firstly you need to install microk8s and werf.
After installing you need to create a secret named 'registrysecret':
$ kubectl create secret docker-registry registrysecret \
--docker-server='https://index.docker.io/v1/' \
--docker-username='<DOCKER HUB USERNAME>' \
--docker-password='<DOCKER HUB PASSWORD>'
$ werf converge --repo '<DOCKER HUB USERNAME>'/'<DOCKER HUB REPOSITORY>'
