05 May 2020 Show Me Your Code with Enrique Paredes: Kubernetes Permission Manager

Enrique will share tips and code around kubernetes permission manager a project that brings sanity to Kubernetes RBAC and Users management, Web UI FTW

27 Mar 2020 CNCF Webinar: Continuous Profiling Go Application Running in Kubernetes

Slides, videos and links from a webinar I have with the CNCF about kubrenetes, profefe, golang and pprof.

04 Feb 2020 Continuous Profiling Go applications running in Kubernetes

Kube-Profefe is an open source project that acts like a bridge between Kubernetes and Profefe. It helps you to implement continuous profiling for Go applications running in Kubernetes.

16 Jan 2020 My experience with Krew to manage kubectl plugins

Kubectl plugins are extremely useful to provide a set of friendly utilities to interact with kubernetes in your environment. Krew is a project that helps you managing the plugin lifecycle. I have to add profefe to it and this is what I learned.

10 Jan 2020 Unit test kubernetes client in Go

A flexible an easy to use testing framework makes all the difference. Kubernetes provides a fake client in Go that works like a charm.

05 Dec 2019 Programmatically Kubernetes port forward in Go

Depending on your networking configuration port forwarding will may be the unique way for you to reach pods or services running in Kubernetes. When you develop a CLI integration that has to interact with pods running inside the cluster you can programmatically do a port forwarding in golang.

Kubernetes it not for operations. It democratize resources and workloads. It can be the solution to bring developers closer to ops. But YAML is not the answer.

14 Feb 2019 Short TTL vs Long TTL infrastructure resource

I called this framework "short vs long ttl". GitOps, Infrastructure as code are an hot topic today where the infrastructure is more dynamic and YAML doesn't look like a great solution anymore. In this article I explain a framework I am trying to use to understand when a resource is good to be managed in the old way or not.

07 Feb 2019 Extend Kubernetes via a Shared Informer

Kubernetes is designed to be extended. There a lot of way to do it via Custom Resource Definition for example. Kubernetes is an event-based architecture and you can use a primitive called Shared Informer to listen on the events triggered by k8s itself.

22 Jan 2019 GitHub actions to deliver on kubernetes

GitHub recently released a new feature called GitHub Actions. They are a serverless approach to allow developers to run their own code based on what happens to a particular repository. They are amazing for continuous integration and delivery. I used them to deploy and validate kubernetes code.

31 Dec 2018 Infrastructure as (real) code

Infrastructure as code today is wrong. Tools like Chef, Helm, Salt, Ansible uses a template engine to make YAML or JSON way to smarter, but comparing this solution with a proper coding language you always miss something. GitOps forces you to stick your infrastructure code in a git repository this is good. But infrastructure as code is way more.

29 May 2018 Cloud Native Intranet with Kubernetes, CoreDNS and OpenVPN

Designing an architecture the network should be a top priority because it is very hard to change moving forward. Even in a cloud environment running on Kubernetes the situation doesn't change. Security and networking are hard pattern hard to inject in old projects. In this talk I will share a practical idea about how to start in the best way with OpenVPN and private DNS in a Kubernetes cluster in order to build your own intranet.

21 Mar 2018 How to use a Forwarding Proxy with golang

Cloud, Docker, Kubernetes make your environment extremely dynamic, it has a lot of advantages but it adds another layer of complexity. This article is about forward proxy and golang.
