I have Coolify building my site and rsync-ing the build output to a separate LAMP server. There was a recent bug in a release that broke compatibility with Nixpacks that broke my previous deployment configuration. To the Coolify team's credit they pushed out a fix within hours (and noted that Nixpacks often has issues where it may break).

To work around this and make my deploys more reliable, I removed my dependence on Nixpacks and updated my site deployment implementation to be handled by Docker directly.

The full Dockerfile is before and — in brief — it:

• Uses the Node.js version 21 container.
• Installs system and PHP build dependencies and cleans up the apt cache
• Sets up the working directory.
• Clones the site source.
• Switches to the app directory the source was cloned to.
• Clears the npm cache and installs Node.js dependencies.
• Installs Composer, my PHP dependencies and optimizes said dependencies.
• Builds the application.
• Creates the ~/.ssh directory in the Docker container, writes the SSH key for the host server to ~/.ssh/id_rsa, sets permissions, adds the destination server to known hosts and rsyncs my build output over.
• Finally, tail -f /dev/null keeps the container running to satisfy Coolify's health check for the build resource.

This process is repeated hourly to refresh the site by a cron job on the host server that makes a post request to the build webhook for the resource.
