Hi Aravind
Thank you very for your response. I like the idea you have suggested but
unable to comment on the code snippet you have attached.
Could you clarify following in bold "as an artefact to all three
downstream pipelines, *which can figure out whether to re-deploy or not.*"
does the pipeline has ability to figure out to run or not based on
artefact or are you suggesting that deployment code can decide whether to
deploy or not in which case all deployment pipeline will run but deployment
code will deploy conditionally.
I was thinking that may be I have to rethink how I setup the pipeline, I
am finding it hard to believe that such a common scenario in today's word
about building microservices, running integration test and deployment of
what has changed should be easy.
Thanks
Anant Agarwal
