A php-buildpack extension for cloud foundry to handle logs better than with php-fpm output.
There is 3 reasons to use another method to forward log to stdout when using php-buildpack:
- By default, php-fpm doesn't forward output from its child to stdout and in the php-buildpack you need to tweak the
php-fpm.confto uncomment the linecatch_workers_output = yes. - Php-fpm add a prefix (with child id) on each message which is annoying for reading and parsing.
- Php-fpm truncate a long log message (see: docker-library/php#207 )
For points 3 a fix is coming but not yet even merged, see: php/php-src#1076
You will need to import this repo to your app folder in the .extensions folder, to do so:
- If your app is a git repo:
git submodule add https://github.com/orange-cloudfoundry/php-logstreamer-extension.git .extensions/php-logstreamer-extension - If your app is not a git repo:
git clone https://github.com/orange-cloudfoundry/php-logstreamer-extension.git .extensions/php-logstreamer-extension
In the next cf push this extension will be loaded.
You will have now have to write your logs on the file path given by the env var LOGS_STREAM, example:
<?php
file_put_contents($_ENV['LOGS_STREAM'], "THIS IS an app log\n"); // you should see, after hitting your page, in cf logs this line without prefix.
