Progressive delivery (blue-green, rolling updates, canaries, etc.) is a set of deployment practices that aim at rolling out new features gradually.
K9s is a terminal-based Vim-like Kubernetes UI.
Everyone is used to Web and desktop dashboards. Kubernetes users are divided between those who prefer performing operations through UIs or through a terminal. How about combining the two modes of operations? K9s is giving us just that. It provides a terminal-based Vim-like UI for operating and observing k8s clusters.
Release frequency keeps increasing and, with it, the need to get away from static environments like staging, integration, and other permanent setups. Dynamic environments based on pull requests are probably the best example of a need for a much higher level of dynamism. Kubernetes allows us to easily create whatever we need, and destroy what is not in use. There is no need for anything, especially not environments to be permanent, except for production. We can get far in that direction by combining GitOps practices and Argo CD in a way that each pull request (PR) creates a new environment that is destroyed when a PR is closed. By doing that, we can improve efficiency while, at the same time, reducing the costs.
After many failed attempts to find a Kubernetes dashboard that is actually useful (even a little bit), I finally stumbled upon Kubevious. There is finally a Kubernetes UI I can recommend.
Octant is all the rage. It’s supposed to be the best Kubernetes dashboard on the market. Yet, I failed to see a reason why anyone would use it. Am I wrong? What am I missing?
Argo CD is a declarative GitOps deployment tool for Kubernetes.
It is one of the best, if not the best tool we have today to deploy applications inside Kubernetes clusters. It is based on GitOps principles, and it is a perfect fit to be a part of continuous delivery pipelines. It provides all the building blocks we might need if we would like to adopt GitOps principles for deployments and inject them inside the process of application lifecycle management.
Argo CD is a tool that helps us forget the existence of kubectl apply, helm install, and similar commands. It is a mechanism that allows us to focus on defining the desired state of our environments and pushing definitions to Git. It is up to Argo CD to figure out how to converge our desires into reality.
