[CentOS-devel] Curating containers

Hi Vašek,
    Yes, I have created pipeline with a nodejs based application(
https://github.com/bamachrn/cccp-demo-test)
with openshift build system. Openshift template is taking the git repo URI
as input, and building, testing within the containers.
As a output this is pushing the ready to run containers to the registry.

Went through the atomic reactor for reading index.yaml and cccp.yaml
written by rtnpro, kbsingh.

I am currently working to understand the openshift template and build
config to automate the build
on git push or scheduled time.

Today I am trying to trigger with Github webhook. This is not triggering
the build due to my IP being in private network.
also waiting for the ci.centos.org access to use jenkins in build process.

Please suggest if there is another way to achieve this.

Thanks
Bamacharan
