PHP Docker images

This repository contains the source for building various versions of the PHP application as a reproducible Docker image using source-to-image. Users can choose between RHEL and CentOS based builder images. The resulting image can be run using podman.

For more information about using these images with OpenShift, please see the official OpenShift Documentation.

For more information about contributing, see the Contribution Guidelines. For more information about concepts used in these container images, see the Landing page.

Versions

PHP versions currently supported are:

• php-7.2
• php-7.3

RHEL versions currently supported are:

• RHEL7

CentOS versions currently supported are:

• CentOS7

Installation

To build a PHP image, choose either the CentOS or RHEL based image:

• RHEL based image

  These images are available in the Red Hat Container Catalog. To download it run:

  $ podman pull registry.access.redhat.com/rhscl/php-73-rhel7

  To build a RHEL based PHP image, you need to run the build on a properly subscribed RHEL machine.

  $ git clone --recursive https://github.com/sclorg/s2i-php-container.git
  $ cd s2i-php-container
  $ make build TARGET=rhel7 VERSIONS=7.3

• CentOS based image

  $ git clone --recursive https://github.com/sclorg/s2i-php-container.git
  $ cd s2i-php-container
  $ make build TARGET=centos7 VERSIONS=7.3

Alternatively, you can pull the CentOS image from Docker Hub via:

$ podman pull centos/php-73-centos7

Note: while the installation steps are calling podman, you can replace any such calls by docker with the same arguments.

Notice: By omitting the VERSIONS parameter, the build/test action will be performed on all the supported versions of PHP.

Usage

For information about usage of Dockerfile for PHP 7.3, see usage documentation.

For information about usage of Dockerfile for PHP 7.2, see usage documentation.

Test

This repository also provides a S2I test framework, which launches tests to check functionality of a simple PHP application built on top of the s2i-php image.

Users can choose between testing a PHP test application based on a RHEL or CentOS image.

• RHEL based image

  This image is not available as a trusted build in Docker Index.

  To test a RHEL7 based PHP-5.5 image, you need to run the test on a properly subscribed RHEL machine.

  $ cd s2i-php-container
  $ make test TARGET=rhel7 VERSIONS=7.3

• CentOS based image

  $ cd s2i-php-container
  $ make test TARGET=centos7 VERSIONS=7.3

Notice: By omitting the VERSIONS parameter, the build/test action will be performed on all the supported versions of PHP.

Repository organization

• <php-version>

  • Dockerfile

    CentOS based Dockerfile.

  • Dockerfile.rhel7

    RHEL based Dockerfile. In order to perform build or test actions on this Dockerfile you need to run the action on properly subscribed RHEL machine.

  • s2i/bin/

    This folder contains scripts that are run by S2I:

    • assemble

      Used to install the sources into the location where the application will be run and prepare the application for deployment (eg. installing modules using npm, etc..)

    • run

      This script is responsible for running the application, by using the application web server.

  • contrib/

    This folder contains a file with commonly used modules.

  • test/

    This folder contains the S2I test framework with a sample PHP app.

    • test-app/

      A simple PHP app used for testing purposes by the S2I test framework.

    • run

      Script that runs the S2I test framework.
