Do you think AIs are going to kill us all one day, or are these AI companies trying to get us to buy into a false narrative for their own benefit?
When working on projects, I generate PLAN and scratch files that are relevant only to me and shouldn't go into the project's .gitignore. To keep them separate, I use local gitignore files that aren't tracked in git I wrote a blog post about how to do this vuyisile.com/setting-up-a...

In this article, I show you how to create and use a local Gitignore file.

Hi everyone, I'm Vuyisile, a technologist based in Zimbabwe. I'm interested in connecting with anyone excited about cloud native technologies, automation, docker, Kubernetes and home labbing.
I'm torn between starting my own agency or working for one.
I've been freelancing for a couple of months now, and while it gives me flexibility over my time, I miss being employed and working as part of a team, having daily stand ups, going through code reviews and attending annual summits in interesting locations.
I've been deploying a lot of front end applications lately so I figured it time to look into the ecosystem deeply instead of blindly deploying. I'm currently leaning React. What are the most important concepts I need to know ?

I set up Paperless-ngx successfully in Kubernetes & uploaded documents. I'll be using it to manage receipts & important records digitally. It has many great features; automatic document classification, tagging, & full text search (even in images). Best of all? It's a Django app!

Storing your Terraform state in a remote backend ensures consistency across teams and machines. This post walks you through setting up Azure Blob Storage as the backend.
Setting Up a Remote Backend for Terraform Using Azure Storage
Terraform Remote State Using Azure Storage Recently, I needed to set up a shared Terraform workflow where state could be safely stored and accessed by a team. I figured out how to use Azure Blob Storage as a remote backend for Terraform. Storing your Terraform state in a remote backend ensures consistency across teams and machines. This post walks you through setting up Azure Blob Storage as the backend.

I configured Terraform to use Azure Blob Storage as a remote backend. Using the Azure CLI, I - Created a new storage account and container - Set up a backend tf file with Azure config and - Ran terraform init to migrate the local state to remote. #azure #terraform
Argo CD is a GitOps continuous delivery tool for Kubernetes. In this post, I cover how I installed and set it up and also share my initial thoughts on it.
GitOps with ArgoCD
I'm learning a set of new tools to make my skills more well-rounded. These include Azure, Terraform and ArgoCD. ArgoCD is a GitOps continuous delivery tool for Kubernetes that's similar to Flux CD, which I used in my Kubernetes homelab. Like Flux CD, it syncs your cluster with configuration data stored in Git. The way it works is that you push changes to Git and Argo CD picks them up and applies them to the cluster.

An intro to Helm
I'm currently learning Helm to improve how I deploy and manage Kubernetes applications. This post is a quick summary of what I've learned so far. Helm is a package manager for Kubernetes. It simplifies deploying and managing Kubernetes resources by bundling them into reusable packages called charts. If you've used apt for Debian-based systems, Helm serves a similar role, except for Kubernetes.

I'm learning Azure & I have only $200 in Azure credit valid for a month, so I need to use it wisely. The advantage of using Terraform is that I can easily destroy all resources I create during my learning sessions, keeping costs low. As you can see from the image below, I've only used 5 cents.
My media server kept freezing and crashing Kubernetes pods. After some digging, I realised the bottleneck was the old spinning HDD. I cloned the system to an SSD, swapped the drives, and the node is now stable and fast. In this post, I talk about how I did it with minimal downtime.

I'm having trouble with my Kubernetes nodes. - Server A has lots of RAM & a fast SSD, but its CPU is terrible & generates too much heat. - Server B has a good CPU, but its disk is slow, & it has little RAM. The best solution is to invest in two mini PCs with SSDs to replace the current hardware.

A server I manage crashed recently due to running out of disk space. The cause was nodejs builds eating up space in node_modules and .cache folders. I cleaned them up, moved builds to a different server & created a cron job to automatically create space by deleting unused files
