Newly created applications have pre-populated git repositories so you can't just at another remote to your existing repository and push to openshift - this is an unnecessary step. This occurs even though I didn't request an pre-existing application.

The pre-existing code had a pre-populated config.ru.

Ruby 2.0 not available

Having ruby '2.0.0' doesn't nicely tell you that you're not running Ruby 2.0 (I had the Ruby 1.9 cartridge installed), it instead barfs out an error like this:

pglombardo@themightyshogun:~/Projects/pwpush-heroku $ git push openshift master

Counting objects: 1253, done.

To get traces generated from a container arrive at the docker host I had to do the following:

On the docker host I run the following to jiggy wig the tracelyzer to listen on something other than 127.0.0.1:

nc -l 172.17.42.1 7831 | nc 127.0.0.1 7831

update: This doesn't forward UDP packets correctly to the dashboard because of a netcat issue. (it was a temporary hack anyways) An IPTables rule or another alternative (socat?) would be a better solution until the Tracelyzer bugfix is shipped.

update 2: Per Adam Tucker, use http://brokestream.com/udp_redirect.c instead

We're happy to say that we recently released the code for the TraceView Ruby instrumentation on Github as Open Source. There are a ton of benefits for AppNeta (and the community) in doing this so making the decision was easy... but the process of actually opening the repository and still keeping a few things private was slightly trickier. Here's the route we took that has worked out really well.

The Situation and Strategy

The Ruby instrumentation has always been sheltered on Github - albeit always in a private Github repository. We used the issues, pull requests and wiki pages extensively for everything from new employee resources to hosting screenshots, customer issues, internal discussions and links to other project and management tools (e.g. Asana).

Outside of the commits and the code, everything else was either of little use to the public or potentially company or customer confidential - stuff that shouldn't or couldn't be shared publicly. So this put us
