Accidentally deleting an application is bad, but accidentally deleting all of them is a lot worse. In this post, I show you how to avoid issues like the following: Argo CD finalizers is a built-in Argo CD feature that confuses many new users and can even result in accidental deletion if you’re not careful. If you see a resource managed by Argo CD that was supposed to be deleted but isn’t, then you can almost certainly blame a finalizer.

In today’s rapidly evolving technology landscape, Kubernetes has become essential for deploying and managing containerized applications. As organizations increasingly rely on Kubernetes to scale their operations, the need for robust guardrails becomes paramount. In this context, guardrails refer to the policies and mechanisms that ensure the safe and efficient operation of Kubernetes environments.

Teams adopting GitOps often ask how to use secrets with Argo CD. The official Argo CD page about secrets is unopinionated by design and simply lists a set of projects that can help you with secrets. We’ve seen several approaches to secret management. These include sealed secrets, the Argo CD Vault plugin, and the External Secret Operator. In this post, we showcase the External Secret Operator and Hashicorp Vault and focus on 2 important aspects.

It's not an understatement to say Dockerfiles are the underpinning of modern DevOps. Writing a simple Dockerfile that 'works' is relatively straightforward, but there are several tricks and tips that could significantly improve the build speed and efficiency of your container images. If your current Dockerfiles copy in multi gigabyte contexts, reinstall dependencies on every build, or use only a single stage, we need to talk.

In the previous blog post in this two-part series, we discussed the critical signals you need to monitor in your Kubernetes environment to ensure optimal resource provisioning. These signals include high CPU and memory utilization, frequent pod evictions, slow application performance, and other indicators that your resources are over- or under-provisioned. Monitoring these signals is essential for maintaining an efficient, cost-effective, and environmentally sustainable Kubernetes environment.
