NGINX 1.14 + PHP-FPM 7.2 container image

This container image includes NGINX 1.14 + PHP-FPM 7.2 as a S2I base image for your PHP 7.2 applications. Users can use CentOS based builder images. The CentOS 7 image is available on Docker Hub as serverbee/nginx-php-fpm-72-centos7. The resulting image can be run using Docker.

Description

NGINX 1.14 + PHP-FPM 7.2 available as container is a base platform for building and running various PHP 7.2 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.

This container image includes an npm utility, so users can use it to install JavaScript modules for their web applications. There is no guarantee for any specific npm or nodejs version, that is included in the image; those versions can be changed anytime and the nodejs itself is included just to make the npm work.

Usage

To build a simple php-test-app application using standalone S2I and then run the resulting image with Docker execute:

  • For CentOS based image 
    $ s2i build https://github.com/serverbee/s2i-nginx-php-fpm-container.git --context-dir=7.2/test/test-app serverbee/nginx-php-fpm-72-centos7 php-test-app
$ docker run -p 8080:8080 php-test-app

Accessing the application:

$ curl 127.0.0.1:8080

Environment variables

To set these environment variables, you can place them as a key value pair into a .sti/environment file inside your source code repository.

The following environment variables set their equivalent property value in the php.ini file:

  • ERROR_REPORTING
    • Informs PHP of which errors, warnings and notices you would like it to take action for
    • Default: E_ALL & ~E_NOTICE
  • DISPLAY_ERRORS
    • Controls whether or not and where PHP will output errors, notices and warnings
    • Default: ON
  • DISPLAY_STARTUP_ERRORS
    • Cause display errors which occur during PHP's startup sequence to be handled separately from display errors
    • Default: OFF
  • TRACK_ERRORS
    • Store the last error/warning message in $php_errormsg (boolean)
    • Default: OFF
  • HTML_ERRORS
    • Link errors to documentation related to the error
    • Default: ON
  • INCLUDE_PATH
    • Path for PHP source files
    • Default: .:/opt/app-root/src:/usr/share/pear
  • PHP_MEMORY_LIMIT
    • Memory Limit
    • Default: 128M
  • SESSION_NAME
    • Name of the session
    • Default: PHPSESSID
  • SESSION_HANDLER
    • Method for saving sessions
    • Default: files
  • SESSION_PATH
    • Location for session data files
    • Default: /tmp/sessions
  • SESSION_COOKIE_DOMAIN
    • The domain for which the cookie is valid.
    • Default:
  • SESSION_COOKIE_HTTPONLY
    • Whether or not to add the httpOnly flag to the cookie
    • Default: 0
  • SESSION_COOKIE_SECURE
    • Specifies whether cookies should only be sent over secure connections.
    • Default: Off
  • SHORT_OPEN_TAG
    • Determines whether or not PHP will recognize code between tags
    • Default: OFF
  • DOCUMENTROOT
    • Path that defines the DocumentRoot for your application (ie. /public)
    • Default: /

The following environment variables set their equivalent property value in the opcache.ini file:

  • OPCACHE_MEMORY_CONSUMPTION
    • The OPcache shared memory storage size in megabytes
    • Default: 128
  • OPCACHE_REVALIDATE_FREQ
    • How often to check script timestamps for updates, in seconds. 0 will result in OPcache checking for updates on every request.
    • Default: 2

You can also override the entire directory used to load the PHP configuration by setting:

  • PHPRC

    • Sets the path to the php.ini file

  • PHP_INI_SCAN_DIR

    • Path to scan for additional ini configuration files

    You can use a custom composer repository mirror URL to download packages instead of the default 'packagist.org':

    • COMPOSER_MIRROR
      • Adds a custom composer repository mirror URL to composer configuration. Note: This only affects packages listed in composer.json.
    • COMPOSER_INSTALLER
    • COMPOSER_ARGS
      • Adds extra arguments to the composer install command line (for example --no-dev).

Source repository layout

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:

  • composer.json

    List of dependencies to be installed with composer. The format is documented here.

Hot deploy

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 to /opt/app-root/src, where the source code is located.

Extending image

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:

Folder name Description
./ 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 RHEL7 is called Dockerfile.rhel7 and Dockerfile for RHEL8 is called Dockerfile.rhel8.

Security Implications

-p 8080:8080

 Opens  container  port  8080  and  maps it to the same port on the Host.
