Hi,

I have four pipelines, two related to seeding data, and two related to continuously update data in elasticsearch. All pipelines share a lot of code. I am planning to run the pipelines in docker, and would like to create a single image such that based on a provided argument start the seed pipelines or the update pipelines.

I have been searching, but I am not sure if I missed some documentation on this. As I understood so far one can either start one pipeline or all inside the pipelines.yml

Thanks!
