Source to Image (S2I) builder for assembling an image that executes a file as part of container execution.

This repo contains both a Dockerfile for building the image.

Bill of Materials

The requirements of this image are simple. All you need are:

• An OpenShift or Minishift cluster
• A git repo with static content in it
• OpenShift Applier to build the image. As a result you'll need to have ansible installed.

OpenShift objects

The openshift-applier will create the following OpenShift objects:

• A Project named build-s2i-executable
• Two ImageStreams named rhel7, build-s2i-executable (see .openshift/template/build-s2i-executable.yml).
• One BuildConfig named build-s2i-executable (see .openshift/template/build-s2i-executable.yml).

Environment Variables

The following environment variables can tune the functionality of the image. These variables can be used in both the build and runtime of the image.

Variable Name	Default Value	Description
RUNTIME_DIRECTORY	/app	Directory containing the executable file
EXECUTABLE_ARGS		Arguments to pass as part of the call to the executable file
