Security or performance is not an important specification for this worker because it is running in "worker" mode - not connected to the internet.

missing entrypoint.sh
I have a designer who is recommending using bedrock + roots - I'm investigating - I have aws + lightsail ($5 / mth) currently all working -
what do you recommend ? switch to digital ocean? I need terminal access + ssl / letsencrypt.

@wweevv-johndpope I've added the entrypoint.sh

I do not want to make blanket recommendations. All providers have their advantages and disadvantages.

AWS Lightsail is a cheap service, but as soon as you switch to the more professional solutions (especially for databases), it gets really expensive.

DigitalOcean App Platform takes care of SSL (if you connect your domain correctly) and you have access to a terminal.
Oh, and you don't need a Dockerfile at App Platform for most projects.
