Building a Kubernetes Operator with the Operator Framework

Annotations in Kubernetes Operator Design
The operator that I've been working on is designed to manage the full lifecycle of a QuestDB database instance, including version and hardware upgrades, config changes, backups, and (eventually) recovery from node failure. I used the Operator SDK and kubebuilder frameworks to provide scaffolding and API support.

Hacking in kind (Kubernetes in Docker)
I've recently been working on an operator (built using the operator-sdk) that manages cluster node lifecycles. Kind allows you to spin up clusters with multiple nodes, using a Docker container per-node and joining them using a common Docker network. However, the kind executable does not allow you to modify an existing cluster by adding or removing a node.

Creating Kubernetes Operators with operator-sdk
To illustrate what we can do with an operator, I will create a proof of concept using operator-sdk. According to the official website::
- What Is A Kubernetes Operator?
-
Writing a Kubernetes Operator
Besides the frameworks TFA lists, you can also build Operators in Ansible or Helm.

Using k8s-apiserver as AAA server for microservices?
Operator SDK is basically just a thin wrapper for kube-builder

You mean the Operator SDK? https://sdk.operatorframework.io

Dont understand how I can watch external resources modification/deletion with my custom operator
yes I agree with youu, an issue has been opened on the operator-sdk github page regarding this topic https://github.com/operator-framework/operator-sdk/issues/6117

You shouldn't run NSA-grade Wi-Fi at home
You can roll your own with https://github.com/smallstep/certificates. We maintain major open source projects and contribute a lot to other projects. I don’t think that means everything we do has to be open source. Sorry this one wasn’t. Doing this in pure open source would be a book, not a blog post.
Love Let’s Encrypt — we’re sponsors — but using them for WiFi is a terrible idea. You need internal PKI for WiFi.

Distributing ACME Let'sEncrypt certs for homelab
letsencrypt was always about moving the public internet off of http, it doesn't really make sense to use it throughout your internal network. but if you really want TLS and ACME for auto renewal, other solutions are available: https://github.com/smallstep/certificates

SSH With SSO
You could try step-ca: https://github.com/smallstep/certificates. There’s an OIDC provisioner for SSO and you can sign (short-lived) SSH certificates with it.

Web application to manage self-signed certificate authorities/certificates/keys
You could also check out out Step CA: https://github.com/smallstep/certificates and the accompanying CLI. It has an ACME server and other methods for requesting certificates. It can work/integrate with your existing root(s), too.

ACME setup. Domain required?
This is a lot more complicated setup but it works for me. I run a private CA called step-ca from smallstep and it provides CA and ACME endpoint. I use a .home domain. The trick is the validation for non-http devices which is typically the DNS-01 challenge. For this, I have unbound in pfsense setup to work with acme-dns so I can keep everything internal. Again its complicated but if your learning cyber security it might help get a handle on all things TLS. Btw way behind the scenes I think the ACME plugin is really just running acme.sh bash script which is really good. Final reminder as other have stated. Private CA is great but you need to distro the roots and intermediates out to your clients for trust. If all your trying to do is have an https web gui for pfsense from one device its pretty easy.

Using k8s-apiserver as AAA server for microservices?
I was just looking at https://smallstep.com/certificates a few days ago. It looks like they have an operator that fits your description as well as example docs for setting up inter-microservice mtls.
