Will see if I can open a PR.

I really discourage this. If you want it, you can create a docker-compose.override.yml file, and add:

services:
  uptime-checker:
    environment:
      UPTIME_CHECKER_ALLOW_INTERNAL_IPS: "true"

Then

docker compose up -d uptime-checker && docker compose restart uptime-checker

I will provide a documentation for this later.

@aldy505 any specific reason? ok thanks.

Putting it on your .env would pollute the file, you need to add inline documentation to know what it's for and which container should it attach to. It's also very prone to typos.

If you use docker-compose.override.yml, you can do so much more than that as seen on this config source code. Some other thing you can do is scaling containers without changing docker-compose.yml, so you can do git pull or git checkout <next version> easily, this is one example of it: https://develop.sentry.dev/self-hosted/tasks/#scaling-workers
