  • The title is “How we do GitOps @ Mettle”. Kubernetes pipeline example article at Mettle, which realizes GitOps using FluxCD.

When building software, understanding how it’s being used by others is often hard to determine. This post, and new tool, analyzes all of the public Puppet code and identifies breaking changes in downstream modules.

  • An introductory article on the OSS tool “Rangefinder” that analyzes users affected when making changes to Puppet modules. Click here for the GitHub page.

An interesting benchmark of how quickly AWS scales up container workloads using the different options; EKS, Fargate and ECS.

  • The title is “Scaling containers in AWS”.
  • An article that reflects my curiosity: “How to scale containers on AWS the fastest way?” It seems that the comparison of Fargate on ECS, EKS, Fargate on EKS was carried out by escalating the ticket to the people in charge of AWS.

A great Serverless case study, looking at a migration from a monolithic architecture to a 100+ Lambda functions running on AWS.

  • The title is “Accelerating with Serverless!”.
  • An example of how LEGO moved from a monolithic architecture to a microservices and 100+ Lambda Function and other AWS services architecture in July 2019.

An interesting look at Rust for developing against the Kubernetes APIs. Some general Rust observations, in particular in comparison to Go.

Docker Compose is a wildly popular tool for standing up a stack of containers. A new effort is starting to standardise the format and make it more applicable to other platforms too.

  • An article explaining the efforts to standardize the Docker Compose format and apply it to other platforms. Click here for the io page.

A set of posts on monitoring Kafka, looking at how to collect the various metrics and which ones are important for maintaining a performance cluster.

  • Two articles, Datadog’s collection of Kafka performance metrics (link above) and monitoring one.
  • Like the product, Datadog’s article is easy to read, so you can read it with confidence. I want to improve my writing.

Tools

Tilt is a development tool focused on helping manage the complexity of microservices. It now has a handy extension mechanism and a shared repository of extensions for various workflows.

Krustlet aims to make it easier to run WebAssembly code on Kubernetes, by providing a custom Kubelet implementation.
