Ask HN: Where can I find some good free MySQL hosting for development?

If this is for development, is there a reason to not run it on your dev machine?

I'm looking into that. Running a VM is easy, I just want to figure out how to deploy docker containers.

I'm not sure how much this solves your problem of "deploying docker containers" but our service Quay.io can be used to push/pull/serve your private binary images. Couple that with something like Digital Ocean's Docker image, and you can deploy docker containers pretty simply.

Amazon RDS has a free tier if you qualify.

I really like Heroku's Postgres service which is free to an extent and then very reasonable for varying levels of production-ness.
