Troubleshooting containers in Kubernetes is a recurring topic that you may face regularly. Logging and monitoring tools come in really handy here as they help you better understanding what is going on in the cluster or in the containers itself. Besides, it is possible to get valuable insights with the help of the classic kubectl commands such as kubectl describe, kubectl logs or kubectl exec. However, in some scenarios, these tools are not enough as you may need to examine the actual incoming and outgoing traffic for the containers in a pod, for example to determine connection issues at TCP […]

Helm is definitely one the most used tools in the Kubernetes world. It comes in pretty handy as it is a deployment tool, a package manager and a templating tool which can help customizing the behavior of application releases based on the values used. Plus, it offers ideal features for its integration in modern CI/CD environments, making it a must-to-have ‘swiss army knife’ in your DevOps toolset. Helm works with charts, which act as independent software packages, but for complex environments in which several charts have to be deployed, there’s no easy way to handle all the releases at once.

Dealing with multiple terraform remote states can become a rather complex task. Besides, querying resources with terraform CLI isn’t very visual 😅. In this post we will present Terraboard, an open source tool developed by Camptocamp that solves these issues. Terraboard provides a web interface which also adds a diff tool to compare different resource versions. It currently supports terraform states in both AWS S3 and Terraform Cloud backends. Testing it locally 💻 Terraboard is distributed as a CLI written in Go, alongside an AngularJS web UI, and it requires a Postgres database in order to work. There are several […]

Let’s be honest, managing Kubernetes clusters is not an easy task, even when it comes to managed Kubernetes services. Controlling the overall infrastructure, performing cluster upgrades and tracking the configuration of each cluster can really become a challenge. Infrastructure as Code (IaC) comes in handy here, with declarative languages such as Terraform and CloudFormation. However, the learning curve of this kind of languages may be steep for those with no previous experience in IaC. Thus, it would be nice to manage clusters in the same way that Kubernetes resources are managed: with manifests and a CLI. In this post, eksctl […]

This is the third post of a collection of GitOps tools articles. In this post, a continuous integration and continuous deployment tool for Kubernetes is reviewed: Werf. If you missed previous articles on GitOps tools, you could give them a read, as it will help you better understanding the general idea. ArgoCD and FluxCD, were the previously reviewed tools. As for the previous tools, an example repository has been developed so that you can test Werf with some existing configurations. You can find the repository here. GitOps & Werf ⛵ GitOps is defined as a way of managing Kubernetes infrastructure and […]
