Caddy + PHP-FPM

This image contains caddy and PHP-FPM in the same container. To run both processes in the same container, we use hivemind, a Procfile compatible process manager.

Usage

FROM ghcr.io/shyim/wolfi-php/caddy:8.3

# Install missing extensions
RUN apk add --no-cache php-8.3-redis php-8.3-gd

# Copy your files
COPY . /var/www/html
docker build -t my-image .
docker run -p 8080:8080 my-image

You can run it for testing purposes also directly, docker run --rm -p 8080:8080 ghcr.io/shyim/wolfi-php/caddy:8.3 and you should see at http://localhost:8000 the php info page.

PHP Extensions / PHP Configuration

As this image bases on fpm, you can check out there how to configure PHP / PHP-FPM and install php extensions.

Caddy Configuration

  • SERVER_NAME - The server name for Caddy. Default is :8000 - This controls also the listing port of Caddy, use :8000 as example for port 8000
  • CADDY_GLOBAL_OPTIONS - Allows setting global options for Caddy like: debug
  • CADDY_EXTRA_CONFIG - Allows setting extra Caddy configuration like add new virtual host: foo.com { root /app/public }
  • CADDY_SERVER_EXTRA_DIRECTIVES - Allows setting extra Caddy configuration for the default virtual host. See here for all options

Overwrite Caddy Configuration

You can overwrite the Nginx configuration by copying your own configuration to /etc/caddy/Caddyfile:

COPY Caddyfile /etc/caddy/Caddyfile

You can find the default configuration here.

Running rootless

You can run the container as a non-root user. The image has a user www-data with UID 82. You can use it like this:

USER www-data
