The InfoQ Podcast

The container runtime is software that executes containers and manages container images. Today, when many people think about a container runtime, they're likely thinking of Docker. However, Docker is more a set of tools for building, packaging, sharing, and running a container via Docker Daemon that then makes syscalls to another tool like containerd. Containerd, in turn, makes calls to an implementation like runc that lays down the file system for the container and is the executor for the process. Today, on The InfoQ Podcast Wes Reisz talks with Phil Estes, one of the containerd maintainers, about container runtimes. The two discuss the significance (in detail) of the announcement that dockerhsim will soon be deprecated in Kubernetes, the complete container runtime stack, work the Open Container Initiative (OCI) is doing today on a third container spec around registries, and more.

The Open Policy Agent is used for policy decision-making across the stack. In the case of Kubernetes, it is often used as an admission controller to protect the API Server with dynamic rules that don’t require recompilation to introduce. Today on the InfoQ Podcast, Wes Reisz speaks with Tim Hinrichs and Torin Sandall (two of the Open Policy Agent Project creators). The three talk about the project, including things like architecture, origin, community, the policy language (Rego), and, of course, performance. The podcast is an introduction to how OPA can is used across the stack for policy decisioning.

Several years ago, today's guest Michael Feathers published a book called Working Effectively with Legacy Code. This book introduced ways of wrangling large codebases. In the book, Feather's discussed leveraging unit tests to introduce--not only a validation of correctness but also-- documentation on a system's operation, ways to decouple/modularize monolithic code, and 24 different techniques to introduce change safely. Today on the podcast, Wes Reisz and Michael Feathers go back and review the book. The two spend some time reviewing key concepts from the book and then discuss how the techniques can be applied today. The two wrap with a discussion on what might change in a new version of the book.
