Also a sysadmin, I've inevitably found that the environment needs/expects a number of services, and it just feels like docker is ill-suited to these use cases.

Also a sysadmin, I've inevitably found that the environment needs/expects a number of services, and it just feels like docker is ill-suited to these use cases. Frequently even the devs themselves want multiple services and can't tolerate stateless systems anyway, but at the very least we have to deal with logging and the like. I'm not saying it can't be done, but I've never found a developer who had a particular desire to implement containers, and even if they did, their concerns don't represent the entirety of what's involved in running infrastructure.
