Minikube is a tool to run Kubernetes locally as a single-node cluster, which is very useful for learning and developing. A regular Kubernetes installation needs at least three hosts. The first one will be the Kubernetes Master, the cluster manager. The rest will be Kubernetes Nodes, which are responsible for running the workloads. Installing kubectl There is a tool called kubectl for managing Kubernetes clusters. We will install it before, and Minikube installation process will configure it correctly.
In a previous post, I talked about my intention to learn about Google Cloud Platform, and thanks to Globant, I had the opportunity to enroll in the GCP Partners Learning Program. Today I completed the Google Cloud Platform Fundamentals: Core Infrastructure course, the first one I did on the platform, so I wish to share with you my achievement and also some thoughts about it. It’s a great training system that takes place in Coursera, it’s seamlessly integrated with Qwiklabs, giving an interactive training experience based on video lessons and hands-on labs.

Seems that I’ll work with Chef soon, so it’s time to review some lessons about it. After browsing the web for a while, I found that using Virtualbox to virtualize infrastructure and Vagrant to manage it as code is the easiest and fastest way to provision new lab environments for Chef. The first step to start working is to create a baseline, a minimal workaround built with one server host and two nodes.
Some time ago I was taking the course Master Microservices with Spring Boot and Spring Cloud but I had to leave it because these days I was getting very busy. Yesterday, after three months, I returned back and after pushing changes to GitLab repo, I noticed that changes were made with my GitHub email address instead of using the GitLab one. Last commit could be easily changed with the command below:
