# August 03, 2016 * Intro by Michelle * [Ryan J](https://twitter.com/ryanj?lang=en) talked about "Defining Applications in Kubernetes(and Openshift). * His presentation can be found [here](bit.ly/sig-apps-openshift) and includes lots of helpful links. * He went through some OpenShift primitives that are not in Kubernetes but may show up soon if the community sees a need. * There was some in depth discussion about Deployments. * Kubernetes has some concepts that came out of OpenShift Deployment Config. * Q: What features are in Deployment Config that are high priority to push into Kubernetes Core at the moment? A: _(Clayton)_ Yes. Handling deployment failures at a high level, a generic idea for a trigger controller which watches another system for changes and makes updates to a Deployment, and hooks. * Ryan showed off OC which is a command line tool which is a wrapper for kubectl * Comment: One of the challenges Kubernetes faces today is that there is not a great way to extensibly pull in new chunks of APIs. * This is something that is actively being worked on today. This work is being discussed and worked on in [SIG-API-Machinery](/sig-api-machinery) * Free O'Reilly EBooks can be found [here](http://gist-reveal.it/4ca683dff6cdb9601c495e27d4bb5289#/oreilly-ebooks) courtesy of Red Hat.
