Infrastructure as Code (IaC) is one of the biggest revolutions in the cloud computing landscape, as it allows automating the deployment of infrastructure based on its definition in the source code. Using code as the source of truth for infrastructure has several benefits: Infrastructure can be versioned as source code normally is, increasing the traceability […]

Kops: deploying Kubernetes programatically ☸️🕹️
Setting up a Kubernetes cluster from scratch can be challenging, specially if you don’t use managed Kubernetes services and you need to guarantee High Availability. Kops (Kubernetes Operations) is an open source tool which helps to set up, upgrade and manage ‘non-managed’ Kubernetes Clusters on top of public cloud providers. In this post, you will […]
Debugging with ephemeral containers in K8s 🔲🔳
Have you ever faced a situation when working with a Kubernetes cluster in which a container within a pod is not working as expected and you need to do some debugging? I’m sure you have. The first step to follow in this troubleshooting scenario would be to try to figure out what’s going on inside […]
GitOps Strikes Back: FluxCD 📟☸️
This is the second post of a collection of GitOps tools articles. In this post, a continuous deployment tool for Kubernetes is reviewed: FluxCD. The previous post focused on ArgoCD. If you missed previous articles on Kubernetes deployments and Helm, give them a read before going through this one, as it will help you understand the general idea a […]

If you missed previous articles on Kubernetes deployments and Helm, give them a read before going through this one, as it will help you better understanding the general idea. GitOps GitOps […]
Building AMIs: Packer and Image Builder⚙️📦
Cloud environments call for dynamic and flexible computing, meaning that fleets of virtual machines can be scaled up and down depending on the load. These machines need a consistent, repeatable and standardized way of setting the startup images and its configuration for the applications that run on them. Pre-built virtual machine images, containing the configuration […]
Helm: Making Kubernetes even better☸️📦
In a previous post, we discussed how to deploy a simple application in Kubernetes, and yet being ‘simple’ we could notice how many different pieces were needed to make a deployment run successfully. Every one of these single pieces can be placed on a separate configuration file to make it easier handling and maintaining the […]
Understanding k8s Deployments☸️💡
If you have already deployed complex applications in Kubernetes, you may have noticed how many different resources you need to deploy and interconnect just to make them work (and thus, this post is going to be just too easy for you). If you’re new to Kubernetes, this post will help you to have a quick […]
Kubernetes: Why, When and How.
Kubernetes, is undoubtedly one the most disruptive tools/technologies that we have seen during the last years within the IT world. Alongside containers and the underlying runtimes, it is redefining the way in which software is built, tested and deployed into production. Although it is more complex to set up and to operate than some other […]
