Most of this is captured in 🐙 github.com/thechangelog/changelog.com/pull/518
We made IAD the primary region (it's the closest one to the origin), discussed VARNISH_SIZE and exposed environment variables as custom HTTP headers. We then struggle with IPv6 DNS resolution. At the end, we are surprised when this starts working all of a sudden.

Ninjastructure: Move fast & break nothing
มุมมอง 192หลายเดือนก่อน
Matias Pan, a professional maté drinker & Senior Software Engineer at Dagger, is showing us an approach to Infrastructure as Code built with Pulumi. We look at Go code, discuss procedural (imperative) vs. declarative, spend some time on state management & introduce the concept of Ninjas in the context of infrastructure: move fast & break nothing. In the second half, Matias uses diagrams to talk...

How does Michal Kuratczyk, Staff Software Engineer at RabbitMQ, access Kubernetes workloads securely, from anywhere? Regardless whether it's a Google Kubernetes Engine (GKE) cluster or Kubernetes in Docker (KiND), Tailscale is a simple solution for this particular use case. This also makes it easy to share private services with all devices on a tailnet, including with friends that want to acces...
Modern CI/CD Pipeline from Scratch (with Dagger TypeScript Modules) - Part 1
มุมมอง 1.1K5 หลายเดือนก่อน
What does it look like to build a modern CI/CD pipeline from scratch in 2024? While many of you would pick GitHub Actions and be done with it, how do you run it locally? And what do you need to do to get caching to work? Tom Chauveau joins us to help Alex Sims build a modern CI/CD pipeline from scratch. We start with a Remix app, write the CI/CD pipeline in TypeScript and get it working locally...

GitOps & ClickOps beyond Kubernetes - Akuity @ KubeCon EU 2024
มุมมอง 1397 หลายเดือนก่อน
The hardest ArgoCD question received was about allowing users to see the diff of their application's rendered output as part of a pull request, given that tools like Customize and Helm obfuscate the fully rendered output through templating. ArgoCD promotes the "rendered YAML branches" pattern, where automation tooling renders the final Kubernetes manifests into separate branches representing ea...
Works on my Computer - Docker @ KubeCon EU 2024

This talk was proposed for KubeCon EU 2024 but didn't make it through the CFP stage. It is an online exclusive! We discuss leveraging Kubernetes for efficient CI/CD processes, exemplified through a live setup of a European Kubernetes cluster. We highlight the flexibility and standardization Kubernetes offers for deployment, and Argo CD's role in automating and managing deployments to reduce hum...
See which line of your Go code allocates the most memory
มุมมอง 769 หลายเดือนก่อน
As of Go v1.22, the Go compiler allows downloading pprof data directly from Parca, which aligns with the Go compiler's expected format, streamlining the incorporation of this data into deployment pipelines. This approach leverages research from Google on Auto Feedback Driven Optimizations, highlighting a departure from traditional PGO requirements of source stability. Instead, Go's PGO can opti...

How to debug a memory issue with Parca?

A team faced a memory spike issue with their database, peaking at 30GB, triggered by a customer complaint about slow queries. Investigation revealed the database's iterator function was using an excessive 14GB of memory. A simple yet effective solution involved updating FrostDB to free dictionaries between record creations, reducing the query's memory usage from 12GB to 2GB. This improvement wa...
