Take a deep dive into what really happens when a pod starts running with Linkerd! Get all the details about init containers, Linkerd's interaction with the firewall and the CNI, and the complex business underlying Kubernetes' container and networking model. Learn everything you wanted to know about container startup ordering and how to deal with it.

What you'll get out of this
  • Learn the details of how Linkerd ties into the Kubernetes container life cycle
  • Understand how Linkerd fits into the Kubernetes networking model
  • Dig into the different ways Linkerd can interact with CNI plugins
  • See how to avoid common pitfalls with container startup ordering
Getting ready

For the hands-on portions, it’s important that you arrive prepared. Please have a Kubernetes cluster ready and the Linkerd CLI version 2.12.0 or above installed on your machine—check out the first few steps of our Linkerd Getting Started Guide if you want some specific instructions on how to do this. (If you don’t want to do the hands-on portion, of course, you are welcome to just listen in. But it won’t be as fun!) Finally, please join the #workshops channel on the Linkerd Slack. We will use Slack instead of the regular Zoom chat for this workshop.

Tech Evangelist

Flynn is a tech evangelist at Buoyant, where he works on spreading the good word about Linkerd — the graduated CNCF service mesh that makes the fundamental tools for software security and reliability freely available to every engineer — and about Kubernetes and cloud-native development in general. Flynn is also the original author and a maintainer of the Emissary-ingress API gateway, also a CNCF project.

Flynn's career in computing spans nearly forty years and runs the gamut from bringup on bare metal to distributed applications, with a common thread of communications and security throughout. He has spoken about Linkerd, Emissary-ingress, and other cloud native technologies at several conferences, including KubeCon/CloudNativeCon, DevOps Days, and the NYC Kubernetes meetup.
