Minimalist Wolfi-based PHP images for building and running PHP applications. Includes both dev and fpm variants.

Download this Image

The image is available on

docker pull

Image Variants

Our latest tags use the most recent build of the Wolfi PHP package. All variants have -dev versions that include Composer and other utilities that are suitable for developing and building PHP applications. Check the Tags page for more details on available tags, and the Details page for information about included packages per variant.

  • latest: This is a distroless image for running command-line PHP applications.
  • latest-fpm: This is the distroless php-fpm image variant, designed to be used together with our Nginx image.

PHP Version

This will automatically pull the image to your local system and execute the command php --version:

docker run --rm --version

You should get output similar to this:

PHP 8.2.1 (cli) (built: Jan  1 1970 00:00:00) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.2.1, Copyright (c) Zend Technologies

Running Composer

To install application dependencies from your host machine, you can use the latest-dev variant with a shared volume:

docker run --rm -v ${PWD}:/work --entrypoint composer --user root \ \
    install --working-dir=/work

Application Setup for End Users

When creating a Dockerfile to extend from these images, the recommended approach is to set up a multi-stage build so that you're able to install your Composer dependencies on a separate environment and then copy the files over to a smaller production image.

CLI Scripts and Applications

The following example demonstrates how to set up a multi-stage Dockerfile build in the context of command line PHP applications:

FROM AS builder
COPY . /app
RUN cd /app && \
    composer install --no-progress --no-dev --prefer-dist

COPY --from=builder /app /app

ENTRYPOINT [ "php", "/app/command" ]

Web Applications / APIs

For web applications, you should follow the same principle, but using the php-fpm variant for the final image. You'll also need a custom nginx.conf file to set up your Nginx service with PHP-FPM.

A good way to test your setup locally is by using Docker Compose. The following docker-compose.yaml file demonstrates how to create a web server environment using the Nginx Chainguard Image :

version: "3.7"
    restart: unless-stopped
    working_dir: /app
      - ./:/app
      - wolfi

    restart: unless-stopped
      - 8000:80
      - ./:/app
      - ./nginx.conf:/etc/nginx/nginx.conf
      - wolfi

    driver: bridge

You'll notice the Nginx service has a volume share to set up a custom config file. The following nginx.conf file sets up Nginx to serve pages from a /app/public folder and redirects requests to .php files to the app service on port 9000.

events {
  worker_connections  1024;

http {
    server {
        listen 80;
        index index.php index.html;
        root /app/public;
        location ~ \.php$ {
            try_files $uri =404;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass app:9000;
            fastcgi_index index.php;
            include fastcgi_params;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            fastcgi_param PATH_INFO $fastcgi_path_info;
        location / {
            try_files $uri $uri/ /index.php?$query_string;
            gzip_static on;

Detailed Environment Information

To obtain information about available modules, you can run:

docker run --rm --entrypoint php -m

To obtain detailed information about the environment, you can run a php --info command on any of the image tags and use grep to look for a specific module or extension.

For instance, to check for curl settings, you can run:

docker run --rm --info | grep curl
