How containers work

Day 1 /  / Track 1  /  EN / Hardcore. Really hard and demanding talk, you'll understand only if you're an experienced engineer.

Containers are rivaled only by "blockchain" and "machine learning" in recent years' hype trends, but they are still quite poorly understood. This talk exposes containers for what they are: ordinary processes, with a bit of isolation, resource quotas, and security sandboxing sprinkled on top. You will learn why containers are interesting and useful, how namespaces isolate containers from each other but can also be used to share resources between containers, how resource throttling works and how it affects the .NET runtime, and how to build minimal .NET Core containers that don't carry 500MB of Ubuntu userspace libraries and tools that you don't need. At the end of the talk, you'll be the go-to person for weird container tricks and scenarios.
