The metabase from render-examples

Following install guide: Metabase crash loop, re: database migration lock, recommend starter-plus as min instance size?

Hey folks,

I just tried setting up a Metabase instance alongside a fresh Render Postgres DB instance per the install guide.
(https://render.com/docs/deploy-metabase)

I ran into the following deployment crash loop in the logs, where it seems like the Metabase server was trying to run its initial DB migrations on the first launch and complained it could not because the database was holding onto a migration lock:

Has anyone else run into this issue on first deployment?

I was able to jump into the Shell in the Render dashboard for the Metabase service and run the java -jar metabase.jar migrate release-locks command.

But the migration lock seems to be a red herring, and the real underlying issue seems to be that the 512 MB of memory available for starter instances is simply not enough to feed the hungry, hungry JVM. It seems like Metabase crashes due to OOM in the middle of the initial migration process.

Maybe the Deploy guide should mention starter-plus as the minimum advisable plan to deploy a Metabase instance?

3 Months Since The Dockerfile Was Updated To The Latest Version Of Metabase

The title says it all. Metabase has had two major releases since then (currently at v 0.43.4 and the file is at v 0.41.7), including important bug fixes. Please update to the latest version.

Metabase is empty?

I had been running Metabase on Render based on this for a while without issue and had saved some dashboards. It has been a couple months since I last logged in and when I visit the URL it's acting like it's a brand new installation, and I had to create my user account again, my data source is missing, etc. What happened?
