I am a very happy user of nanobox, i was able to deploy to linode after migrating from GCP app engine, relatively painless. Their whole suite of tools made it easy to not scew up that..first deploy to the new server shudders
Were you running a docker image on custom VMs on app engine? Just wondering how easy the transition was. Are you still running on Google cloud instances via nanobox?
i was using flex python 3 engine, not custom.
I am not running on GCP anymore, I switched to Linode because it's cheaper ($5 instance) and deployed using nanobox.
I deployed to app engine using app engine deployment, Linode using nanobox
