Latest PHP Composer build on top of Alpine Linux.

• php-7.0, latest (Dockerfile)
• php-5.6 (Dockerfile)

Alias

function composer() {
    docker run --rm -it \
        -v $(pwd):/usr/src/app \
        -v ~/.composer:/home/composer/.composer \
        -v ~/.ssh/id_rsa:/home/composer/.ssh/id_rsa:ro \

Check Composer health

You may want to check first the health of composer with:

$ composer diagnose

If you are on macOS, using VirtualBox and the diagnose check reports some networking problem like so:

[Composer\Downloader\TransportException] The "http://packagist.org/packages.json" file could not be downloaded: php_network_getaddresses: getaddrinfo failed: Try again
failed to open stream: php_network_getaddresses: getaddrinfo failed: Try again
Checking https connectivity to packagist: FAIL

You could fix it with this:

$ docker-machine stop [machine-name]
$ VBoxManage modifyvm [machine-name] --natdnsproxy1 off --natdnshostresolver1 off
$ docker-machine start [machine-name]

Custom PHP settings

Note this image is builded with no PHP memory limit (and other few settings), have a look to their respective php.ini file.

You may want to override and add your own settings.

Add an extra line to your alias :

• PHP7 : -v /path/to/your/php/settings.ini:/etc/php7/conf.d/50-setting.ini
• PHP5 : -v /path/to/your/php/settings.ini:/etc/php5/conf.d/50-setting.ini
