Creating a basic S2I builder image and application container

This repository, along with https://github.com/flannon/static-site, implements an example showing the full cycle of s2i deployment. To run the static site you can do the following,

 make
 oc new-app flannon/s2i-nginx~https://github.com/flannon/static-site --name mysite
 oc expose svc/mysite

Getting started

This assumes you have a version of OpenShift greater than 3.6 running and that you've logged in.

Makefile

Running make will create the builder image called flannon/s2i-nginx and deploy it to the OpenShift docker registry. When make finishes you can check the builder image,

docker images | grep flannon/s2i-nginx

Building the application image

The application image combines the builder image with the applications source code, which, in this case, is the static website at https://github.com/flannon/static-site.git. Running new-app against the builder image with the source repository

 oc new-app flannon/s2i-nginx~https://github.com/flannon/static-site --name mysite

will tart a container from the builder image; inject the contents of source repository into the build container according to the instructions in the assemble script; make the application image from the current state of the builder container; and finally start the application container, which presents all the resources assembled during the build processes.

Making the application available

In order to access the application you'll need to open it's service port,

 oc expose svc/static-site

Once you've exposed the port you can run

 oc status

to get the URL of the static site, or check the project folder in the OpenShift console.
