A beginner's guide to Linkerd by "that DevOps guy"

In his fun and insightful Linkerd intro video, Marcel Dempers, a.k.a. that DevOps guy, walks you through deploying a sample microservices architecture. Roll up your sleeves and deploy Linkerd along as Marcel discusses the service mesh’s individual components, opt-in features, and injects and finds network bugs. To follow along, make sure to check out the source code on Marcel’s GitHub repo.

Linkerd, a Deep Dive into the Service Mesh

Ever wondered how Linkerd looks under the hood? In this deep dive session, Linkerd core maintainer Zahari Dichev walks you through Linkerd’s ins and outs. He also discusses the service mesh’s new multi-cluster functionality released in 2.8. You’ll learn how traffic in Linkerd is routed transparently across clusters based only on native Kubernetes primitives. Zahari concludes with a demo of Linkerd’s traffic shifting features that split traffic between services living on different clusters.

Validate Linkerd on your own Kubernetes Cluster

Is your Linkerd installation running at peak performance? At our September Linkerd Community Meetup, Mayank Shan presents the work he’s been doing on conformance validation as part of Google’s Summer of Code. By running a set of tests on your cluster, you can sleep comfortably at night knowing all of Linkerd’s functionality works with your specific cluster’s configuration. Mayank discusses why conformance validation is needed, how he implemented it with the help of VMWare’s Sonobuoy, and shows how you could validate your own cluster.

Topology-Aware Service Routing on Kubernetes with Linkerd

Interested in making sure requests stay within the same node or availability zone? Then service topology is for you! At our September Linkerd Community Meetup, Matei David discusses what service topologies are and how he implemented them over the summer as part of CNCF’s Community Bridge program. Matei explains why endpoint slices are required as well as what they do for end users. He shares what was difficult with the project and some tips for what else can be done.

Service Mesh Lessons Learned

Service meshes are gaining traction in the cloud native community. In their ServiceMeshCon EU 2020 talk, Buoyant CEO and Linkerd maintainer William Morgan and IBM’s Lin Sun discuss what they’ve learned from implementing Linkerd and Istio service meshes respectively, and how service mesh usage in practice has challenged their early assumptions and design decisions.

KubeCon Panel: Service Mesh Q&A

In this interactive KubeCon discussion moderated by IBM’s Lin Sun, Buoyant CTO Oliver Gould, Christian Posta (Solo.io), Sven Mawson (Google), and Daniel Berg (IBM) take questions from the audiences about all things service mesh. As we are seeing an increase in service mesh adoption, users are leveraging them to solve the rising challenges of microservices in a consistent manner. Challenges include how to observe microservices, handle network failures, control traffic, or secure microservices without redeploying your services.

Introduction to Linkerd

During his KubeCon EU 2020 introduction to Linkerd, William Morgan provides an overview of the CNCF service mesh project. Incredibly fast with an ultralight footprint, Linkerd is an open governance, Kubernetes-native service mesh. Watch his presentation to learn what it does, why it’s useful, and how it differs from other service meshes.

The Fastest Deployment Time: How to Code at Lightning Speed

XKCD famously joked about what programmers spend most of their time doing. Do you need to spend so much time every day waiting for something to compile? Many developers wait for 30 minutes or more to see the results of changing a single line of code. Follow along with us as we go from 30 minutes down to mere seconds. In this video, our own Thomas Rampelberg and CNCF Ambassador Ellen Korbes will walk through multiple strategies you can use for any kind of containerized application to reduce the amount of time you’re spending looking at cat memes every day.

Nondestructive Forensics: Debugging Kubernetes Services without Disturbing State

In this KubeCon talk, Alex Leong discusses how to debug Kubernetes services using tools such as Linkerd, debug sidecars, and ephemeral containers. While some errors may take a long time to reproduce – resource leaks and race conditions are a good example – others occur unexpectedly in prod. In both cases, it is key to collect as much information as possible without restarting the pod. Ephemeral containers are a promising technology yet still in alpha.
