-Dockerfiles to demonstrate installing Python on different operating systems and using them with Apama
+# Apama core python installation in Docker
+
+This project contains Dockerfile for installing Python 3.6 on various Linux
+base images. It also contains a simple Apama project to demonstrate use of
+this Python with Apama.

+
+## Using the Dockerfiles
+
+To use these Dockerfiles you will need a copy of the Apama 10.3 core
+installation from [http://www.apamacommunity.com](http://www.apamacommunity.com/). Unpack it into this directory
+under a folder named 'core'.
+
+Next, choose one of the following Linux distributions to use as your base image:
+
+* CentOS 7 (Installs Python from EPEL repository)
+* Ubuntu Bionic (Installs Python from main repository)
+* Debian Buster (Installs Python from main repository)
+* OpenSuse Leap 15 (Installs Python from main repository)
+* Ubuntu Xenial (Installs Python from a PPA)
+* Debian Stretch (Builds Python from source)
+* Debian Jessie (Builds Python from source)
+* OpenSuse Leap 42 (Builds Python from source)
+
+Once you have chosen the distribution and release to use as a base image, build the image with:
+
+    docker build -t projectimage -f Dockerfile.distribution:release .
+
+Once that has completed you can run the demo project in the docker image with:
+
+    docker run --rm -t -i projectimage
+
+## Using Python within Apama
+
+For more details about how to use Python within Apama please see the documentation and forums on [http://www.apamacommunity.com](http://www.apamacommunity.com)
