VCAP_SERVICES available for local development via AF TUNNEL

[mexitek]

VCAP_SERVICES environment variable is essential to continuous integration and deployment strategies. af tunnel command is extremely useful for local development. It allows for our code to be versioned locally and for our dev db to be kept in appfog for syncing purposes.

The only key missing is allowing our app to grab database credentials from VCAP_SERVICES environment variable locally. CLI tools can not write environment variables for all user on any given machine. Environment variables created by af command line tool will only be available to af and not our app. This pull request writes the VCAP_SERVICES data to a file locally, allowing our app to look for it IF the environment variable does not exist.

PHP Example

# Check for AppFogs ENV variable
if( getenv("VCAP_SERVICES") ) {
    $json = getenv("VCAP_SERVICES");
} 
# Check for local file, placed by: af tunnel
else if( file_exists("/etc/af_vcap_services") ) {
    $json = file_get_contents("/etc/af_vcap_services");
} 
# No DB credentials
else {
    throw new Exception("No Database Information Available.", 1);
}

# Decode JSON and gather DB Info
$services_json = json_decode($json,true);
$mysql_config = $services_json["mysql-5.1"][0]["credentials"];

This works for me, not sure if it might work for others. Might need some adjusting.

Great addition, +1 for this, would be extremely helpful with local development.

I actually did almost exactly this in my own setup, so +1 from here.
Not sure I wanna place it in /etc though – I placed it in the project folder – but somewhere is definitely better than nowhere!

Is there any movement on this? It would be really handy.

Not sure AF took the changes. But this issue has the appropriate changes on
it. You can take in those changes locally.
