The Enemy Within: Running Untrusted Code in Kubernetes

Containers are a great way to deploy and isolate application resources but they can fall short when it comes to security isolation. How do you improve the security of a container while maintaining the flexible and dynamic resource usage of a container? There are many options for sandbox containers but which is right for you?

In this talk I will explore sandbox runtimes in depth with a focus on use-cases and challenges on their implementation and maintenance. I will dive into the container security model, the use cases for sandbox pods. I will discuss various approaches and their tradeoffs before diving into the architecture of gVisor, how it differs from virtual machine based sandboxes, and how we are working to make running untrusted code feel more like the containers you know and love. Finally, I will bring it all together with a demo of best practices for using gVisor to run untrusted user code in a Kubernetes cluster.
