MongoDB Proper Kubernetes installation with Helm
Overview
In a previous post I created my own MongoDB deployment and installed with Kustomize. Let’s use the “official” Bitnami Helm Chart to install MongoDB.

MongoDB Kubernetes Deployment
Overview
While writing Tagging Asteroids with MongoDB I was able to quickly provision a cluster on the free tier of MongoDB Atlas. What I originally wanted was to quickly stand up a MongoDB instance in my Kubernetes environment but found most documentation too complex for my usecase. Just give me a MongoDB “dialtone” as quickly as possible without having to install the binaries on my system.
Tagging Asteroids with MongoDB
Objective
Let’s use MongoDB to build an asteroid tagging engine that allows us to assign multiple elements to any asteroid then query based on those elements.
Firefox: The WidevineCdm plugin has crashed
Firefox 108.0.1 (64-bit) - “The WidevineCdm plugin has crashed”
While studying for my CKAD on Udemy over the holidays I encountered this error when attempting to open ANYTHING that had DRM protected video; Udemy, Netflix, Hulu, etc. Some recommended fixes included maintaining a separate firefox
binary. Luckily I found the fix on AskUbuntu.com
Pi-Hole Wildcard DNS
In order to access Kubernetes applications via my ingress projectcontour.io, I’ll use a wildcard DNS entry.
Unfortunately this isn’t a simple entry in the web UI for Pi-hole (yet?). A quick search and Brandon Rozek had documented the steps to add a wildcard DNS entry in dnsmasq
.
Homelab
Objective
To have a single server with enough power to run nested vSphere 8 and Tanzu Kubernetes Grid with NSX. But with vSphere 8 I wanted to make sure I had something on the HCL. Dell PowerEdge R740 will carry the homelab moving forward.
K8s Waiting for Condition=Available=True
While working with Ansible for standing up a vanilla Kubernetes 1.25.5 cluster I found myself separating the the initial bootstrapping of the cluster, which includes intalling the CNI antrea
from the rest of the configuration (metrics
,metallb
,contour
) due to waiting for antrea
to become Ready.
