Merged: No

Describe your changes

Context
While trying out Netbird for the first time self-hosted for my homelab, I was auditing the installation script. I have a Caddy proxy already set up to do TLS termination for various subdomains and would like to install Netbird on the same VPS. However, don't want to run 2 instances of Caddy and the explicit bind to :80 prevented me from doing that.

Change 1 - Use checkip.amazonaws.com instead of jsonip.com
I felt this was more sustainable and reliable long term, and as a side effects obviates the need for jq.

Change 2 - Stop explicitly binding to port 80 in Caddy
Assuming the :80 bind is only to allow for automatic certificates, it is unnecessary in Caddy. But more importantly, this allows me to import the Caddyfile from my main Caddyfile. Specifying the port 80 bind prevents all my other domains from responding to ACME challenges.

This was easy enough for me to workaround on my own, but figured I'd contribute the change back upstream. Prost!

Select exactly one:

I added/updated documentation for this change
Documentation is not needed for this change (explain why)

Technically this changes removes the jq requirement for the install script. But I noticed some of the other installation scripts require it, so I think leaving the jq requirement documented is wise.

Summary by CodeRabbit

Chores
- Streamlined setup scripts by removing jq dependency requirement
- Updated external IP address detection to use AWS service
- Refined Caddy web server configuration formatting and security headers
