feat: Self-Hosted Guide with just Docker?

[deadcoder0904]

Is your feature request related to a problem? Please describe.

Why not provide a simple Docker guide rather than platform-specific guides?

Describe the solution you'd like to see

A simple Docker step-by-step guide.

Describe alternate solutions

I guess I can perform trial & error with other guides (fly, supabase) to see what environment variables are required but would prefer a step-by-step answer.

Do I need all of these environment variables? or only 5 of these mentioned in Kubernetes docs? Like if I compare, I do see an extra RUNTIME_PLATFORM?

Also, are the self-hosted docs for v2 or v3? I'm trying trigger for 1st time only so don't know.

Additional information

I understand it goes against business incentives but if you're gonna promote it, you should provide a step-by-step guide in the docs. Otherwise, it just seems like a marketing gimic. Even though it does look easier to figure it out but would be cool if it follows Supabase footsteps. In the end, the best product wins :)
