What is Pi-hole? Pi-hole is a DNS sinkhole, used as a network-wide DNS level ad and malware blocker that works with domain blocklists and enforces it. The idea here is simple, you point it to blocklists that are available on the internet (it comes with one pre-enabled), and it takes care of preventing any of your devices from trying to reach those domains. Common examples are activity tracking websites and malware domains that should never be contacted. ...
Now that I have a Kubernetes cluster handy, I wanted to get my hands dirty by deploying my first application on it. What else is better than running an application I wrote myself to learn something to double up on the investment? If you want to read up on Short{Paste} , the application I wrote, you may read my blog post on it. App deployment I started by switching from Global to the Local cluster’s Default namespace/project. From the Workload tab, clicking on Deploy takes me to the deploy workload page. Here, I start by naming the workload as shortpaste and selecting the docker image adyanth/shortpaste. I leave the port mapping empty for now since I plan to add a layer 7 Ingress rather than a layer 4 NodePort or a Layer 4 load balancer. Under environment variables, I add what my app expects. Finally, for now, I let the scale default to 1 and hit Launch. ...
While my NUC homelab handled what I considered “production” workloads using docker and compose, I wanted to play around with and learn Kubernetes. I understood most of the bird’s eye view concepts like pods, deployments, and ingress, but without much hands-on, most of it was fleeting. So I decided to put my spare RAM and CPU on my desktop to good use by installing a complete K3s cluster. A good part of my research was provided concisely on an excellent guide by Tom . ...
Quick links: Git Repo DockerHub Drone Build Heroku Demo I was recently roped into the world of Go (Golang) while working on building the terraform provider for Cisco FMC at work. This beautiful language that amalgamates the speed and friendliness of C to modern creature comforts offered by the likes of Python was a refreshing experience. I had a ton of hands-on with making API calls and handling state in Go. Although I still am yet to explore in-depth the largely uncovered areas of goroutines and channels, before going there, I wanted to understand database ORM modeling, used quite frequently in many backends. ...
