I work for an extremely large - £Billions - retail grocery operation in the U.K. We use Docker containers in production, not right across the business, but in many important and up-and-coming areas. What did you want to know?

I was really looking to take an informal poll to see how common containerization is in production, but now that you've asked, I guess my questions revolve around the technology stack:

Are you using kubernetes for orchestration?

Is there automation managing the orchestration configurations like Puppet, Chef, Ansible, Saltstack?

Can I assume this is being carried out through virtualization, if so, what kind of hypervisor is in use?

Is this on premise or in the cloud?

More questions to come, I'm sure and thanks in advance for indulging my curiosity!

Yes on Kubernetes - it's not a platform in and of itself, but an excellent place to found a platform. Automation everywhere. Chef and Ansible, but not on the same project. It's all AWS-based. We do use ECS on occasion but it's not great. As others have said, the main issues are developing the entire CI/CD pipeline.
