proxy_set_header Host $http_host;

Is there an easier way to implement this? For example, integrating this logic into a single plugin, or adopting an easier alternative approach.

Move from standalone container to separate web and data containers

This is an advanced setup. Don’t follow this unless you are experienced with Linux server administration and Docker. 2 Container Setup for a New Site Added by @pfaffman 2019-12-11. NOTE: If you want to create a 2 container site you can do this: ./discourse-setup --two-container It works just like normal except it’ll create separate data and web_only containers and generate a random password for the database. If you already have an app.yml you’ll need to rename it, or discourse-…

Sidesteps this - it allows you to bootstrap whilst still online, then switch out the containers resulting in seconds of downtime, not minutes. It is then arguably pointless to have an offline page.

The other benefit is that you can confirm the success of the build via the bootstrap before committing to it , potentially saving you hours of downtime.
