Pull Request Overview

This PR adds support for configuring trusted domains in the code-server module to enable link protection functionality. Users can now specify a list of domains that should be trusted when code-server validates external links.

• Adds a new trusted_domains variable to accept a list of trusted domain strings
• Updates the run script to process the domains and pass them to code-server via --link-protection-trusted-domains flags
• Integrates the trusted domains configuration into the coder_script resource environment

Will look into testing more this week, as well as adding tests specifically for this new feature.

@Foorack Have you tested this module to make sure it works after the update?

This doesn't interpret correctly.
