phpdockerio/php74-swoole repository overview

⁠Note: this image is deprecated

Please switch to phpdockerio/php:7.4-swoole. More info at https://hub.docker.com/repository/docker/phpdockerio/php⁠

⁠PHPDocker.io base images

Repository of base images for PHPDocker.io⁠ generated environments.

Images are built daily⁠ in order to fetch the latest base image changes as well as available php versions.

⁠OS Base images & PHP Package Sources

All images use an Ubuntu LTS release as base image, except for PHP5.6 which uses Debian Jessie. For each of these base OS images, we use a third party source for the PHP packages - these packages come from Ondřej Surý⁠ who is the official maintainer for PHP in Debian which is the origin of all packages in Ubuntu.

In most cases, we override Ubuntu's PHP packages with Ondřej's to ensure we always have the very latest. For instance, Ubuntu 20.04 comes with php 7.4.3 but we still install Ondřej's packages to ensure you get the absolutest latest version of php 7.4 every time. Ubuntu backport security fixes, but not necessarily bugfixes from later patch releases.

⁠Image types

Each PHP version has its own image, and for each php version, we have a cli and an fpm variant. These two are identical, except for the fact the fpm contains php-fpm and their default command is of course php-fpm.

We're using CMD instead of ENTRYPOINT because I don't want to dictate how you use these images. If I were to set an ENTRYPOINT you would not be able to easily open a bash shell into either container using docker run or docker exec or docker-compose equivalent without you needing to re-build the container.

⁠Built-in php extensions

Each image contain the extensions below. Some versions of PHP have the same functionality in core - for instance, json is part of core PHP in php 8+:

• APCu & APCu-bc
• cURL
• JSON (from 8.0, part of php core)
• MBString
• MCrypt (php <= 7.0)
• OPCache
• ReadLine
• Sodium (from 7.1; from 7.2, part of php core)
• XML
• ZIP

These are the minimum extensions I consider necessary for any modern PHP app. They're required by the likes of composer, the symfony/* libraries etc.

⁠Composer

All images use the composer v2. If for whatever reason you need to roll back to v1, add the following to your Dockerfile

COPY --from=composer:1 /usr/bin/composer /usr/bin/composer

⁠Available images:

Notes:

• Unsupported versions are past PHP EOL (End of Life)
• Daily builds are turned off for versions that run on an OS base that's also EOL (for instance, Debian Jessie)
• Daily builds are kept for PHP versions that have reached EOL but the base OS has not - the base OS still receives security updates, including the PHP runtime.
• In general, do not use any unsupported images in a production environment, regardless of whether daily builds are still enabled
• Old images are kept in docker hub in the interest of enabling legacy apps to run
• Also, old images could potentially be deleted by Docker Hub if they go unused for a certain period of time - if this happens, they won't be restored and you need to upgrade.
• Ondřej Surý is PHP's package maintainer in Debian. His Ubuntu PPA allows us to have more up to date packages beyond those provided by the base image OS.
