Over the weekend I decided to learn my way around Docker (I'd tried once before but it just didn't stick). Now Tuesday afternoon, I've reached a point where the basics (and cutting and pasting from tutorials) mostly make sense. Moved a full-stack web app (node/express, apollo, graphql, redis, react) into Docker, got the whole thing SSLed and deployed on a new $5/mo. Linode VPS. If I can move a few other things over there (other Node apps, a Wordpress install), maybe I can ditch my original Linode and get my monthly bill back down from $10 to $5?
Stretch challenge: Most of my node apps use MongoDB's Atlas -- the free tier, but still... would self-hosting inside containers improve performance?
