This container image includes PHP 5.6 as a S2I base image for your PHP 5.6 applications. Users can choose between RHEL and CentOS based builder images. The RHEL image is available in the Red Hat Container Catalog as registry.access.redhat.com/rhscl/php-56-rhel7. The CentOS image is then available on Docker Hub as centos/php-56-centos7. The resulting image can be run using Docker.
PHP 5.6 available as container is a base platform for building and running various PHP 5.6 applications and frameworks. PHP is an HTML-embedded scripting language. PHP attempts to make it easy for developers to write dynamically generated web pages. PHP also offers built-in database integration for several commercial and non-commercial database management systems, so writing a database-enabled webpage with PHP is fairly simple. The most common use of PHP coding is probably as a replacement for CGI scripts.
For RHEL based image
$ s2i build https://github.com/sclorg/s2i-php-container.git --context-dir=5.6/test/test-app rhscl/php-56-rhel7 php-test-app $ docker run -p 8080:8080 php-test-app
For CentOS based image
$ s2i build https://github.com/sclorg/s2i-php-container.git --context-dir=5.6/test/test-app centos/php-56-centos7 php-test-app $ docker run -p 8080:8080 php-test-app
Accessing the application:
$ curl 127.0.0.1:8080
To set these environment variables, you can place them as a key value pair into a
file inside your source code repository.
The following environment variables set their equivalent property value in the php.ini file:
The following environment variables set their equivalent property value in the opcache.ini file:
You can also override the entire directory used to load the PHP configuration by setting:
You can override the Apache MPM prefork settings to increase the performance for of the PHP application. In case you set the Cgroup limits in Docker, the image will attempt to automatically set the optimal values. You can override this at any time by specifying the values yourself:
MaxClientsbefore version httpd 2.3.13.
TOTAL_MEMORY / 15MB. The 15MB is average size of a single httpd process.
You can use a custom composer repository mirror URL to download packages instead of the default 'packagist.org':
composer installcommand line (for example
You do not need to change anything in your existing PHP project's repository. However, if these files exist they will affect the behavior of the build process:
List of dependencies to be installed with
composer. The format is documented
In case the DocumentRoot of the application is nested within the source directory
users can provide their own Apache .htaccess file. This allows the overriding of Apache's behavior and
specifies how application requests should be handled. The .htaccess file needs to be located at the root
of the application source.
In order to immediately pick up changes made in your application source code, you need to run your built image with the
OPCACHE_REVALIDATE_FREQ=0 environment variable passed to the Docker
-e run flag:
$ docker run -e OPCACHE_REVALIDATE_FREQ=0 -p 8080:8080 php-app
To change your source code in running container, use Docker's exec command:
docker exec -it <CONTAINER_ID> /bin/bash
After you Docker exec into the running container, your current directory is set
/opt/app-root/src, where the source code is located.
Not only content, but also startup scripts and configuration of the image can be extended using source-to-image.
The structure of the application can look like this:
|Can contain additional Apache configuration files (|
|Can contain shell scripts (|
|Can contain own SSL certificate (in |
|Application source code|
Dockerfile and other sources are available on https://github.com/sclorg/s2i-php-container. In that repository you also can find another versions of PHP environment Dockerfiles. Dockerfile for CentOS is called Dockerfile, Dockerfile for RHEL is called Dockerfile.rhel7.
Opens container port 8080 and maps it to the same port on the Host.
