Learn from the Kubernetes Dungeon Masters: Managing Multiple Kubernetes Clusters

As a cloud engineering team supporting multiple development teams, we needed a Kubernetes solution to allow us to manage multiple Kubernetes clusters. Additionally, we wanted to offload the administrative overhead of managing our Kubernetes clusters to reduce our internal administrative workload. We will talk through how we've leveraged Rancher and EKS to solve our needs.

Instrumenting Ruby on Rails with Prometheus

If you’re running a production application, you need metrics. There are great products out there that allow you to gain visibility into how your application is performing, give some nice graphs, and charge you for it. In the Rails community, this is commonly achieved by using NewRelic and Skylight. But for some of us, we achieve visibility by using Prometheus and Grafana that we build and host ourselves.

Infrastructure Ops in 2019 - How Legacy Technology Compounds Technical Debt (1/2)

In today’s software-driven economy, every organization faces an imperative to modernize the way they deliver software in order to adapt and enable the digital era — or perish. Digital transformation across industries is driving the need for IT to enable Cloud-Native applications. This has led enterprises to adopt Kubernetes as the most effective way to support cloud-native architectures and to modernize their applications and IT infrastructure.

Docker Image vs Container: Everything You Need to Know

Docker is a powerful tool for creating and deploying applications. It simplifies rolling out applications across multiple systems and is a useful tool for integrating new technologies. An application that runs using Docker will start up the same every time on every system. This means that if the application works on your local computer, it’ll work anywhere that supports Docker. That’s great news! It simplifies your development process and can be a powerful tool for continuous delivery.

Developing a Go app with Docker Compose

Writing Go applications in an isolated environment with Docker comes with some great advantages. You get a clean GOPATH, the bare essentials for developing, and you can easily change which Go version you’re developing against. In this quick tutorial, we’re going to show you how to structure a Go application with Docker Compose as your development environment.

Understanding Istio Ingress

Istio is a hot technology right now. Giants such as Google and IBM have devoted entire teams of engineers to the project to push it to production readiness. Since 1.0 has been released recently, I wanted to write down some of the things that confused me coming from a strictly Kubernetes only world where we have Ingress controllers and Service load balancers and how Istio takes these same concepts but on stimulants.
