Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

LoadBalancer type service on bare-metal
They have F5 CIS (Container Ingress Services) https://github.com/F5Networks/k8s-bigip-ctlr which is made specifically for this. They can do a Loadbalancer service or a more custom CRD.

- What Is A Kubernetes Operator?
-
Why is Kubernetes adoption so hard?
It worth adopt proper controller development with something like Metacontroller, Kopf or Java Operator SDK.
- What is your approach to adding custom labels to a pod in a deployment that's managed by a helm chart?
-
is there a way to set expiry date for k8s rbac setting?
There are many frameworks, like the Operator Framework (https://operatorframework.io/) to the MetaController (https://github.com/metacontroller/metacontroller) to KubeBuilder(https://github.com/kubernetes-sigs/kubebuilder) to the Kubernetes Operator Framework (kopf, https://kopf.readthedocs.io/en/stable/), among others.
-
Is there a tutorial on how to write an Operator in Go?
You might like a little alternative to writing your own in the first instance:) take a look at https://metacontroller.github.io/metacontroller/
-
Writing an Operator from scratch
Codegen is not magic, but if you want to make it simple stupid, supportable and prod-usable I'd go for metacontroller. There's not much magic to it - just common admission/validation webhooks propagated to your controller implementation, alongside the simplest possible reconciliation cycle. We had adopted Knative driven metacontrollers and it's a pretty solid approach.
-
For what should I take a look?
https://github.com/metacontroller/metacontroller - Sounds cool! I will look into it.
-
Dynamic Mutating Pod Admission Controller?
When I need a quick mutating controller, I like to use MetaController, which makes rapid prototyping really easy: https://metacontroller.github.io/metacontroller/
-
Best option to write a CRD today?
If you are more into lightweight and common use cases, look at metacontroller or the shell-operator.
-
What's the number one annoyance that drives you crazy about Kubernetes?
In case you've not heard of it, the metacontroller aims to do exactly this. It provides the controller-lifecycle (registering your types, watching the API for changes, etc), you just need to provide a HTTP webhook to receive the JSON object, and respond with the modifications\resources you want.

kubernetes - Production-Grade Container Scheduling and Management
Nuclei-Template-CVE-2022-1388-BIG-IP-iControl-REST-Exposed - This vulnerability may allow an unauthenticated attacker with network access to the BIG-IP system through the management port and/or self IP addresses to execute arbitrary system commands, create or delete files, or disable services. There is no data plane exposure; this is a control plane issue only.
