Minimal image of Nginx + PHP-FPM running on Alpine.

With this image 👏 you can deploy your PHP project to Heroku via Container Registry 👏 because layer count and image size are decreased as much as possible to meet Heroku's restriction.

This is just an example. It's of course ready for Composer.

$ cd /path/to/your-php-project
$ tree .
.
├── index.php
└── Dockerfile

0 directories, 3 files

<?php
// index.php
echo 'Hello, Heroku Container Registry!';

# Dockerfile
FROM ttskch/nginx-php-fpm-heroku

# as will be described later, just for local development
USER nonroot

$ heroku login
$ heroku container:login
$ heroku create {appname}
$ heroku container:push web
$ heroku open

Then you can see 'Hello, Heroku Container Registry!' on https://{appname}.herokuapp.com

Of course you can run your app locally on this image too.

$ docker build . -t {sometag}
$ docker run -p {port}:8888 -v $(pwd):/docroot {sometag}

Or

$ heroku container:push web
$ docker run -p {port}:8888 -v $(pwd):/docroot registry.heroku.com/{appname}/web

Then browse http://localhost:{port}

See examples.

• Less number of layers
• Small image size
• Nginx correctly listens to $PORT which set by Herkou web dyno on runtime
• As Heroku recommends, can run as non-root user locally (Many permission problems are solved)
