Introduction

Reusable Docker base image for Laravolt/Laravel deployment. The image extends ServerSideUp PHP and adds Laravolt-friendly PHP extensions plus a small entrypoint hook that can run php artisan laravolt:link during container startup.

Published Images

Docker Hub: https://hub.docker.com/r/laravoltdev/image

Recommended tag for Laravolt v7 applications (PHP 8.5 branch preview):

docker pull laravoltdev/image:php8.5-prod

Compatibility tags are kept for existing apps:

Tag	Purpose
laravoltdev/image:php8.5-frankenphp-debian	Recommended PHP 8.5 FrankenPHP Debian runtime
laravoltdev/image:php8.5-prod	Production alias for deployment images
laravoltdev/image:latest	Latest recommended production runtime, currently PHP 8.5 on this branch preview

Release builds also publish versioned tags such as php8.5-frankenphp-debian-vX.Y.Z, php8.5-prod-vX.Y.Z, and php8.5-base-vX.Y.Z.

Included PHP Extensions

The image explicitly installs the extensions commonly needed by Laravolt v7 applications:

• bcmath
• exif
• gd
• intl

ServerSideUp already ships common Laravel runtime extensions such as zip, PDO database drivers, and Redis on the recommended FrankenPHP images. Keep those available through the upstream base instead of reinstalling them here.

Laravolt Entrypoint Hook

Set these env vars to auto-run Laravolt asset linking when a Laravel app is mounted/baked into the image:

AUTORUN_ENABLED=true
AUTORUN_LARAVOLT_LINK=true
APP_BASE_DIR=/var/www/html

The hook is safe to skip: if Laravel or Laravolt is not installed, it exits without failing the container.
