Checkout github pull requests locally

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

Debug PHP in Docker with PHPStorm and Xdebug

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 \

How to get the hostnames and informations of other hosts in the same docker scale grouping. http://stackoverflow.com/a/39895650/3423324

The way I could do it was by using the docker api. I used the docker-py package to access it.

The api exposes a labels dictionary for each container, and the keys com.docker.compose.container-number, com.docker.compose.project and com.docker.compose.service did what was needed to build the hostname.

The code below is a simplified for code I am now using. You can find my advanced code with caching and fancy stuff that at Github at luckydonald/pbft/dockerus.ServiceInfos (backup at gist.github.com).
