Debug your PHP in Docker with Intellij/PHPStorm and Xdebug

1. For your local dev, create a Dockerfile that is based on your production image and simply install xdebug into it. Exemple:

FROM php:5

RUN yes | pecl install xdebug \
    && echo "zend_extension=$(find /usr/local/lib/php/extensions/ -name xdebug.so)" > /usr/local/etc/php/conf.d/xdebug.ini \

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

Download File from URL

Proof-of-concept to download a file from a URL and save it locally. For example, I may wish to retrieve a JAR file from Nexus.

Uses the http package, which does the basics with raw HTTP protocol support.

Possible update: use request, it is like the Python's requests library. There is a companion package called node-request-progress that tracks download progress. See request-progress on GitHub.

Note: The request package has been deprecated.

Gitlab won't allow reuse of a public ssh key for multiple accounts. To get around this you need to create a second ssh key for the second account.

Create or modify your ~/.ssh/config file:

# normal                                                                                                                                                                  
Host gitlab.com-work_username
     HostName gitlab.com
