My Process Used Minimal Memory, and My Docker Memory Usage Exploded

The Docker infrastructure abstracts a lot of aspects of the creation of images and running them as containers, which we usually do not know about nor interact with. One of those aspects is the handling of the filesystem inside the container. This post is a case study on how we discovered that writing large amounts of data inside a container has side effects with memory caching. Initially, we thought that we had an issue with our source code, but this was never the case.

A 5 Minute Guide for Experimenting with Ambassador and Jaeger in a Kubernetes Sandbox

Implementing distributed tracing is fast becoming a fundamental expectation when building modern (distributed) systems. However, this is yet another thing for developers to learn, and configuring distributed tracing on Kubernetes is hard, right? Actually, no. Getting started with Jaeger on Kubernetes has never been easier.

Monolith to Microservices - A Thought Leadership Talk

On November 11, 2020, I had the pleasure of speaking with two incredible thought leaders in the DevOps space: Vivek Pandey, VP of Engineering at Shipa (https://www.shipa.io), and Patrick Deuley, Sr Product Manager at GitLab (https://www.gitlab.com). The topic of the discussion was “Monolith to Microservices,” and we covered three key areas: Starting out, Scaling and Developer Experience.

Managing Your Full Application Lifecycle Using #GitOps

#GitOps is nothing new. Or, to be more precise, the principles of GitOps existed long before the term was invented. But hey, that's the pattern in our industry. It is the fate of all good practices to be misunderstood, so we need to come up with new names to get people back on track. That is not to say that we are in a constant loop. Instead, I tend to think of it as a periodic reset trying to eliminate misinterpretations. GitOps is one of those resets. It fosters the practices and the ideas that existed for a while now and builds on top of them.

Scaling Fleet and Kubernetes to a Million Clusters

We created the Fleet Project to provide centralized GitOps-style management of a large number of Kubernetes clusters. A key design goal of Fleet is to be able to manage 1 million geographically distributed clusters. When we architected Fleet, we wanted to use a standard Kubernetes controller architecture. This meant in order to scale, we needed to prove we could scale Kubernetes much farther than we ever had.
