Resume-Operator - Jeff Davis - resume.jefedavis.dev

A Kubernetes operator built with operator-builder.

This respoistory and it's companion Resume serves two purposes:

• Backup of my resume for rapid deployment and development
• Showcasing some skills while I'm at it:
• Golang
  • Docker
  • Kubernetes
  • Kubernetes Operators
  • CI/CD
  • GitHub Actions
  • MakeFile
  • Hugo Web Framework
  • HTML5, SCSS
  • Writing Great Documentation

Why

I hate updating resumes, It's not so much writing the content that I dislike. Instead, it's messing with Word and other tools to adjust margins, dealing with columns, page breaks and just formatting in general. So, why not use a data structure language like YAML and let programming deal with all of the formating. Plus, the portability and rapid deployments are a big upshot as well.

Now I can store all my expierence, certifications, skills, and projects in kubernetes manifests and let the code handle the rest. I work with Kubernetes and Kuberentes Operators quite a bit, why not practice what I preach?

OK, but is a Kubernetes Operator really necessary?

Absolutely not, but it was a fun exercise and a neat talking point. Additionally with the other tools I've built and worked on (yot and operator-builder) I was able to create a fully functional operator in about 30 minutes.

K8s Architecture Overview

Local Development & Testing

To install the custom resource/s for this operator, make sure you have a kubeconfig set up for a test cluster, then run:

make install

To run the controller locally against a test cluster:

make run

You can then test the operator by creating the sample manifest/s:

kubectl apply -f config/samples

To clean up:

make uninstall

Deploy the Controller Manager

First, set the image:

export IMG=myrepo/myproject:v0.1.0

Now you can build and push the image:

make docker-build
make docker-push

Then deploy:

make deploy

To clean up:

make undeploy

Companion CLI

To build the companion CLI:

make build-cli

The CLI binary will get saved to the bin directory. You can see the help message with:

./bin/resumectl help
