 ## Step 3 - Build your image
 Use `s2i build` to create your Docker image from source code. You will need Docker installed on the machine and optionally git if your source code is in a public git repo. You can choose from three python builder images
 
- * Python 3.6 : seldonio/seldon-core-s2i-python36:1.14.0-dev seldonio/seldon-core-s2i-python3:1.14.0-dev
+ * Python 3.6 : seldonio/seldon-core-s2i-python36:1.15.0-dev seldonio/seldon-core-s2i-python3:1.15.0-dev
    * Note there are [issues running TensorFlow under Python 3.7](https://github.com/tensorflow/tensorflow/issues/20444) (Nov 2018) and Python 3.7 is not officially supported by TensorFlow (Dec 2018).
  * Python 3.6 plus ONNX support via [Intel nGraph](https://github.com/NervanaSystems/ngraph) : seldonio/seldon-core-s2i-python3-ngraph-onnx:0.1
 
 Using s2i you can build directly from a git repo or from a local source folder. See the [s2i docs](https://github.com/openshift/source-to-image/blob/master/docs/cli.md#s2i-build) for further details. The general format is:
 
 ```bash
