DevOps

In order to troubleshoot a problem we needed to duplicate the list of selected resources.

I wanted to go over some of the technological changes I went through and a very high level overview of how I accomplished them.

Building a bunch of Raspberry Pi's led me to wanting a default authentication certificate and disabling the certificate check.

The KeyVault is picky about PEM certificates. Very picky.

I am migrating everything to a new Raspberry Pi cluster and need to build multi-architecture images through an Azure DevOps pipeline. Here is how I did it.

My Ghost site was getting slow. I decided to make it a static site. Here is how I did it.

I want to run postfix in a container as a mail relay for my network. Here are the problems I ran in to and how I solved them.

First, I like Windows Terminal and it is only getting better. Second, I want to start it with multiple tabs. Here is how I did it.

This guide can be used for deploying any helm chart for a 3rd party repository through Argo. I am basing this around NGINX though.

Deploying the Kubernetes Dashboard through Argo and Kustomize with ingress and a service account.

I'm playing with GitOps and I'm using ArgoCD for my orchestration engine. I want to let it rule itself through the git repository.

I built my cluster, now I wanted to make a new user with full privileges.

I am working on rebuilding my Kubernetes cluster with containerd as the CRI. I have to use an init file to specify the cgroup.

I'm building some NuGet packages that I want to be publicly visible and I wanted things like a project website URL, license, author, etc. added to the metadata without modifying the csproj file.

Continuing my venture into Kubernetes I got annoyed that I had to add the imagePullSecrets to all of my pods. Turns out, there's a way to do it at the namespace level. It cannot be done at the cluster level.

Now that I put debmirror in a container, it was time to run the entire thing in Kubernetes. This includes running the site to serve the mirror, and a cron job that will run the container to sync the repositories.

As I'm moving everything into Kubernetes I needed a way to run debmirror in a Docker container to synchronize my apt repositories.

Getting a Storage Class in Kubernetes with NFSv4 turned out to be relatively simple. My setup is using Rancher, Kubernetes and my shared storage is using NFS.

Key Vault is pretty nice, I really like the built in support for IOptions. I wish it allowed periods, but it doesn't. At least the work around was easy.

To handle blue/green of the services in much the same manner, we were going to have 2 queues, a blue and green.

On my fresh, brand new installs, of Debian 10, Kubernetes pods could not talk to the outside world, nor could they talk to each other on the same node.

Install Debian by only supplying a static IP address during install and install Docker configured for Kubernetes

As we write more services we need a consistent and easy way of monitoring them.

Now that I have IPv6 with Comcast working I wanted to make things automatic. I'm going to use radvd for that.

Here's a general overview of my setup, Comcast Business for my internet, a Raspberry PI running Debian 10 (Buster) as my firewall/router.

Once the reboot was completed I used fdisk to resize the partition then resize2fs to resize the filesystem. I did not unmount the filesystem during this process, EXT4 can be resized online.

As I installed Rancher OS in Hyper-V I ran into a couple of issues. Here's what they were and how to get around them.
