3 months ago I can open jupyter notebook on google cloud with:

gcloud compute ssh gpu-1 --zone=asia-east1-b 
docker start tensorflow1 && docker exec -it tensorflow1 bash 
jupyter-notebook --no-browser --port=8888 --allow-root

but now I can't. After careful examination，I found one sentence:

Ubuntu's Kubernetes 1.14 distributions can bypass Docker and use containerd directly

Is it this reason that I can't open jupyter notebook? should I use containerd with:

snap install microk8s --channel=1.14/beta —classic

or maybe other reasons that cause my problem
