cron PHP application docker images - Webserver

Abstract

Part of the docker-phpapp image suite.

See https://github.com/cron-eu/docker-phpapp-php/ for a complete explanation and example usage.

This is the Webserver container, with images for amd64 and arm64 (i.e. also run on Apple M1).

Tags available

  • croneu/phpapp-web:apache-2.4

Currently, only Apache 2.4, so that the .htaccess files work out of the box. This is based on the official image with pre-configured VirtualHost's to work with any PHP-FPM image.

It also includes full HTTP/2 and HTTPS support.

To activate HTTPS, simply generate your certificates with mkcert and include these in your .env - the image will automatically use these and generate a valid HTTPS Vhost.

croneu/phpapp-web settings

  • APP_WEBROOT: defaults to /app/html, change, if your application public folder is not called html. Examples:

    • TYPO3@cron: /app/html
    • Laravel: /app/public
    • Neos: /app/Web

  • HTTPD_EXTRA_CONF: multiline string of extra configuration to put into httpd.conf. For example can be used to load extra Apache modules, i.e.

    HTTPD_EXTRA_CONF="
LoadModule deflate_module modules/mod_deflate.so
"

  • SSL_CRT, SSL_KEY: Add your SSL certificate and private key here (the PEM strings, not the filenames) to enable Apache with SSL support. It will automatically listen to port "8443"

  • WEB_PORTS_HTTP and WEB_PORTS_HTTPS: comma separated list of ports the webserver should bind to. Defaults to 80 and 443 but you can add additional ports for convenience, i.e. 8080 or 8000. This makes the webserver reachable through the same ports as they are via docker port mapping and could ease working with i.e. 404-handling, direct mail fetching, solr indexing. See below for an example.

Using

To access the web-server, make sure you have a DNS entry in your local /etc/hosts or local DNS server:

For docker-machine:

192.168.99.100 my-app.vm

For Docker for Mac or locally on Linux:

127.0.0.1 my-app.vm

Then you can access the web-server:

Ports and hostname

You can also make the other containers access it with the same hostname and port. Sample docker-compose.yml for that:

services:
  web:
    image: croneu/phpapp-web:apache-2.4
    ports:
      - "8080:80"
      - "8443:443"
    volumes:
      - app:/app
    environment:
      WEB_PORTS_HTTP: '8080 80'
      WEB_PORTS_HTTPS: '8443 43'
    networks:
      default:
        aliases:
          - my-app.vm

This way you can reach http://my-app.vm:8080 from outside and also from inside docker (other containers).

SSL certificate

Generate a SSL certificate with mkcert and configure it in your .env:

mkcert my-app.vm
( echo 'SSL_CRT="' ; cat my-app.vm.pem; echo '"' ; echo 'SSL_KEY="' ; cat my-app.vm-key.pem ; echo '"' ) >> .env

Your .env should then contain something like:

SSL_CRT="
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
"

SSL_KEY="
-----BEGIN PRIVATE KEY-----
...
-----END PRIVATE KEY-----
"

Docker Image Development

Build is triggered automatically via Github Actions.

To create them locally for testing purposes (and load created images to your docker):

make build BUILDX_OPTIONS=--load PLATFORMS=linux/amd64
