• Updated Compose to version v0.28.0.
• Reviewed the original plane repository and removed unnecessary command sections.
• Updated the proxy container.
• Updated the template for the environment because nginx is gone and has been replaced by Caddy.
• Removed the unnecessary domain variable.
• Added the full URL of the repository.
• Added proxy_config and proxy_data volumes as needed.
• Replaced "https" with "http" on CORS, as in the original Compose file.
• Removed the version because the plane requires the latest Compose file version.
• Updated the meta file to v0.28.0.
• Replaced rabbitmq_user with ${rabbitmq_user}.

I used this Compose file and environment on my production server, and everything is working correctly. There were no errors during the build, and there are no errors in the logs.

Edited: I tested the Base64 configuration on the preview site. Everything works correctly. The only thing is that you need to wait a while for everything to get ready.
