Opinionated ReactPHP optimised PHP Docker images

Images

This repo builds two different images, plus a -dev image for each containing composer, bash, git, ssh, strace, gdb, and make, and a -root image for all *(-dev) images where the default user is root. All the images are based on Alpine Linux and Debian Linux. All images come with extensions used to increase the performance of ReactPHP (such as event loop extensions). Such extensions are highlighted build in the extensions list below. All the Alpine Linux images are scanned for vulnerabilities, and not pushed if any are found. The Debian Linux containers easily a few hundred so those aren't scanned. (There is no use in doing so.)

CVE Matrix

Currently Alpine and Debian images are treated differently, this matrix defines the differences between Alpine and Debian images:

Base Image	Description
Alpine	Don't push when CVE's are found when building
Debian	Not scanned for CVE's due to the ton of low CVE's found in there

The available tags

These images are published to Docker Hub as wyrihaximusnet/php:OUR-TAGS and to the GitHub Container Registry as ghcr.io/wyrihaximusnet/php:OUR-TAGS.

In order to provide upgrade path we intend to keep one or more versions of PHP.

The tag naming strategy consists of (Read as a regex):

• PHP: (phpMajor).(phpMinor)-(nts|zts)-(alpine((alpineMajor).(alpineMinor))|bullseye|buster|strech)(-slim)(-dev)(-root)?
  • Example: 8.2-zts-alpine-slim, 8.4-nts-alpine3.13-dev, 8.1-zts-buster-slim

Example usage

The following example has two build staging, the first for leading in any required dependencies, and the second the actual image we'd want to use. In the second stage we copy the dependencies in without needing composer in the production image. We create the image with the following command:

docker build . -t IMAGE_NAME:TAG --target=runtime

FROM ghcr.io/wyrihaximusnet/php:8.4-zts-alpine-slim-dev AS install-dependencies

WORKDIR /opt/app

COPY ./composer.lock /opt/app/composer.lock
COPY ./composer.json /opt/app/composer.json
COPY ./src/ /opt/app/src/
RUN composer install --ansi --no-interaction --prefer-dist --no-dev -o

FROM ghcr.io/wyrihaximusnet/php:8.4-zts-alpine-slim AS runtime

WORKDIR /opt/app

COPY ./composer.lock /opt/app/composer.lock
COPY ./composer.json /opt/app/composer.json
COPY --from=install-dependencies /opt/app/vendor/ /opt/app/vendor/
COPY ./src/ /opt/app/src/
COPY ./app.php /opt/app/app.php

ENTRYPOINT ["php", "/opt/app/app.php"]

NTS

NTS, or non-thread safe is the PHP version most people use. This image comes with the following extensions:

Extension	Description
ext-eio	Provides interface to the libeio library
ext-pcntl	PCNTL OS signals
ext-uv	LibUV event loop
ext-event	Libevent event loop

ZTS

ZTS, or zend thread safe is the PHP version that is safe to be used and required my threading extensions such as pthreads or parallel. This image comes with the following extensions:

Extension	Description
ext-eio	Provides interface to the libeio library
ext-parallel	A succinct parallel concurrency API for PHP7 using threads
ext-pcntl	PCNTL OS signals
ext-uv	LibUV event loop

Both versions come with the following list of non-non-blocking related (core-) extensions:

• bcmath
• Core
• ctype
• curl
• date
• dom
• ffi
• fileinfo
• filter
• ftp
• gd
• gmp
• grpc
• hash
• iconv
• json
• libxml
• mbstring
• mysqlnd
• openssl
• opentelemetry
• pcre
• PDO
• pdo_pgsql
• pdo_sqlite
• pgsql
• Phar
• posix
• protobuf
• random
• readline
• Reflection
• session
• SimpleXML
• sodium
• SPL
• sqlite3
• standard
• tokenizer
• vips
• xml
• xmlreader
• xmlwriter
• zip
• zlib

Slim images

Slim images include all the above extensions except the following, as those notoriously require heavy dependencies:

• gd
• vips

Installing extensions

These images come with both PECL and PIE for any additional extension needs.

Tag last pushed

The following table lists when each base tag was last pushed to Docker Hub and the GitHub Container Registry. Timestamps are sourced from Docker Hub; both registries are updated in the same CI push. Variant tags such as -dev, -slim, and -root are omitted as they are all built and pushed at the same moment.

This project is based on Usabilla's PHP Docker Template. Lots of the documentation on that repository also applies here, with the big difference that this project only supplies CLI images.
