A lot of services default to HTTPS. For instance, try setting up an internal Gitlab instance with runners, pipelines, and package/container registries that actually works. It's an absolute nightmare, and some things outright won't work. And if you want to pull images from HTTP registries with Docker, you have enable that on every instance for each registry separately. You'd be better off registering a real domain, using Let's Encrypt with the DNS challenge, and setting up an internal DNS for your services. That is literally an order of magnitude less work than setting up HTTP.
