I actually really love containers so I will bite on this:

1) We use containers all over our process. From local development to production. In production we run in AWS ECS Service clusters with 9 containers per cluster. These are mostly rails servers and nginx reverse proxy's.

2) We run rails servers, nginx reverse proxy's, CI/CD uses containers, we have jobs for data processing that use containers. Probably other things too.

3) Things :D

4) Yes and no. We don't use orchestration tools but we do have orchestration using customer rake tests and deep integration with our CI/CD environment.

5) It's hard to hug a container... that's the biggest challenge.
