Thanks for the detailed response! It all makes sense, and it sounds like y'all are getting good advice. My gut take on docker vs. config management came from the trend of IaaS providers moving higher up the chain in the services they offer (it ain't just compute anymore). So spinning up an ephemeral environment that also, for example, had its own SQS instance, or an Aurora DB, or (across clouds) had a Firebase DB or Cloud Scheduler configuration, seems like a very common use-case. Gotta start somewhere though, and docker's probably a good place to do so. Looking forward to trying it out!
