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.
Linkerd rebuilds its continuous integration (CI)
With Kubernetes In Docker (KinD) and GitHub Actions In this 2020 KubeCon EU presentation, our own Andrew Seigner shares how we migrated our continuous integration (CI) system built on a GKE cluster and Travis to a system running eight one-off Kubernetes in Docker (KinD) clusters in parallel via GitHub Actions. Running all serialized tests on a single Kubernetes cluster took the legacy CI system about 45 minutes followed by an often multi-hour backup.
Enforcing Automatic mTLS With Linkerd and OPA Gatekeeper
In this KubeCon talk, Microsoft’s Rita Zhang and our own Ivan Sim discuss how Linkerd and Gatekeeper can be leveraged to automate and enforce mTLS policy in production.

Over the past 2.5 years, Leo and his team worked with the Linkered community, leveraged with Consul, Nginx, Prometheus, and deeply customized Linkerd with Plugins to build up the service mesh.
Searching Reusable Code in the Kubernetes Codebase
In his KubeCon talk, Kevin Lingerfelt discusses how open source software and Go’s support for remote import paths simplify importing and running code from some of the most popular open source projects directly in your own project. Occasionally, finding that one piece of code in a large codebase for your use case can feel like a scavenger hunt. But the spoils of the hunt are vast. Kevin explores how Linkerd has leveraged the Kubernetes codebase to replace their code with existing code that’s more robust and better tested.
Nordstrom, Kairos, and Attest share application monitoring best practices with Linkerd
In this live discussion moderated by DigitalOcean’s Michelle Peot, we’ll hear from infrastructure platform owners at Nordstrom, Kairos, and Attest on how they use Linkerd as part of their broader application health monitoring strategy to secure, monitor, and observe Kubernetes applications. The conversation covers a lot of ground, including how these organizations have architected their infrastructure, which teams are responsible for application health, how they use Linkerd as part of their application health strategy, and the most challenging aspects of monitoring application health.
Multi-cluster observability with Kubernetes, Linkerd, and Thanos
Uniform observability across polyglot applications can be challenging, even more so across multiple clusters. In this talk, Andrew Seigner from the Linkerd team will demonstrate adding observability to applications across multiple Kubernetes clusters with zero code changes, and then using Thanos to enable observability across all clusters in one unified view. This talk will outline how Linkerd uses Prometheus to provide zero-config observability for applications running in Kubernetes, and how Thanos enables observability to scale across any number of Prometheus instances.
Strava uses Linkerd to avoid service outages
Strava has been running Linkerd in production for over a year, and almost every internal app uses it for service discovery and routing. From incident response workflows to candidate deployments, Linkerd plays an integral part throughout Strava’s infrastructure stack. In this talk, J Evans, Infrastructure Engineer at Strava will describe Strava’s real-world use case for Linkerd. He will describe how they use Linkerd’s Prometheus and Statsd integrations to respond to service outages, and how these observability tools along with other Linkerd features can even be used to avoid such outages in the first place.
Tokio-Trace: Scoped, Structured, Async-Aware Diagnostics
Networked applications often rely on asynchronous programming to achieve high performance and throughput. However, since execution in asynchronous software switches between tasks based on IO readiness, log messages from these systems becomes difficult to interpret. Tokio-Trace is a new diagnostics framework for the Rust programming language that provides primitives for instrumenting asynchronous systems. Unlike traditional logging, Tokio-Trace emits structured diagnostics that include the contexts of causal relationships between events.

Noorali is a key contributor to the Helm project, the most commonly used package manager for Kubernetes. Noorali and Matei broke their talk into four chunks: Why bother debugging your applications on Kubernetes.
How Planet Uses Linkerd For Monitoring Satellite Data
Kubernetes can handle dying nodes and failing pods, but it can’t help when your application returns failure errors, slows down, or suffers from a sudden spike in traffic. In this talk, Nic Cope from Planet Labs, deep dives into how CNCF’s service mesh, Linkerd and Prometheus provide cluster wide visibility analytics for Planet Labs global network of micro-satellites. With these analytics, Nik’s team is able to monitoring latency and service failure for all events.
Why And How We Integrated Prometheus With Linkerd 2
Prometheus is an open-source tool used to record real-time metrics in a time series database. Linkerd 2.0 integrates Prometheus directly, so that users can instantly observe live service behavior from the command-line and access rich service-level metrics with zero configuration upon installation. In this talk, open source software engineers Andrew Seigner from Linkerd and Frederic Branczyk from Prometheus provide a useful overview of each project and share how the Prometheus integration scrapes metrics from every Linkerd proxy to give users access to lots of very useful metrics.
