System never sends Set Password/Reset Password emails, although other emails are sent fine

I recommend just using a complete Ubuntu VM and running the default installer there.

However, if you are experienced with Linux/Cloud/Docker you can:

  • Bootstrap the image somewhere

  • Push the bootstraped image to a Docker registry somewhere

  • Deploy the bootstrapped image

Bonus points if you do it behind a load balancer, using managed PostgreSQL and Redis, using a CDN, sharing a block storage for compiled assets, automatic scaling with health check, etc… The rabbit hole goes on.
