Talk and example about Kubernetes Operators

These requirements are adapted and stolen from Demystifying Kubernetes Operators with the Operator SDK: Part2

• golang v1.10+
• dep v0.5.0+
• git
• docker v17.03+
• kubectl v1.10.0+
• An account on DockerHub
  • There is a way of doing local Docker repo, but I haven't taken the time to prove this out
• operatro-sdk
• microk8s
  • Some have reported a conflict with minikube, however, I haven't run into this.

All examples assume you have done this!!!

It is recommend that in a shell that you create the following alias:

alias kubectl="microk8s kubectl"

Please do not create this as a default (part of your .profile or .bashrc) since you will probably need kubectl for other work and this alias will bite you in the butt.

Sandbox Readme

kubectl config view

There you will find the server endpoint: https://127.0.0.1/16443

The user is admin.

The password is plain text.
