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.

RSE Rave Recurrence
I had a really (what I thought at the time) cool idea for a new Kubernetes storage driver, so I implemented the basic version in an evening. That's the first "rave-worthy" event - the architecture of these drivers is fairly complex and there are many ways to do it (see https://github.com/container-storage-interface/spec/blob/master/spec.md) so getting something working as I imagined it, knowing nothing beforehand, was the first moment of joy. The next day (after sharing in a few slacks) I got a DM from a tech lead at and he was really excited about the idea! That second affirmation that someone was excited about the project and wanted to brainstorm with me was my second moment of joy. And then for the third, last night and (some of today, still going to do more after dinner soon!) I've been doing detail work, and learning a ton, debugging, learning, making it slowly better... that flow state (often with music) is probably the closest thing to the idea of a rave. Anyway, that's my story! I love learning Kubernetes stuff, I'm so grateful I've been able to in my current role.

Infrastructure Engineering — Deployment Strategies
But if all of these are not an issue, then Containers and an orchestration system like Kubernetes can always take care of workload portability especially with OCI now in place for containers and CSI, CNI, CRI, SMI for storage, networking, runtime and service mesh respectively creating a healthy standards based ecosystem for all thereby enabling workload portability without lock-in since for a workload to be truly portable, all the underlying resources should be portable without any/very limited changes.

Infrastructure Engineering - Diving Deep
CSI (Container Storage Interface) is a standard which helps establish interoperability between multiple storage providers avoiding the need to have in-tree plugins within the core. So, any storage provider who supports CSI can work with Kubernetes without any issues. You can find a complete list of providers supporting CSI here

Long, detailed post mortem on a reddit failed k8s upgrade
When the Gatekeeper validatingwebhook came up, I was really worried that'd be the issue! Regardless I'd recommend anyone who cares about their cluster not collapsing to change the gatekeeper webhook to only intercept resources you care about: https://github.com/open-policy-agent/gatekeeper/pull/1806
- Is OPA Gatekeeper the best solution for writing policies for k8s clusters?

Implement DevSecOps to Secure your CI/CD pipeline
Kyverno adds an extra layer of security where only the allowed type of manifest is deployed onto kubernetes, otherwise, it will reject or we can set validationFailureAction to audit which only logs the policy violation message for reporting. Kubewarden and Gatekeeper are alternative tools available to enforce policies on Kubernetes CRD.

Gatekeeper with Istio
Now, we have the hardest part resolved and let's turn our attention to the OPA Gatekeeper. Gatekeeper uses the OPA Constraint Framework to describe and enforce policy. Right now there are mainly 3 parts we should pay attention:

10 Essentials For Kubernetes Multi-Tenancy
They enable you to establish the policies and regulations that govern cluster deployments and applications. Using predefined policies, policy engines can dynamically modify or create configurations. Policy engines such as Gatekeeper and Kyverno can be leveraged to meet legal and compliance requirements while maintaining operational flexibility and development speed.

Kubernetes for Startups: Practical Considerations for Your App
Setup policy around what resource requirements can be requested by an app per environment. OPA and gatekeeper or kyverno can help. Setup access control for who can create or modify apps.

Kubernetes policy management: I - Introduction
OPA Gatekeeper is an open source, general purpose policy engine. OPA decouples policy decisions from other responsibilities of an application, like those commonly referred to as business logic. OPA works equally well making decisions for Kubernetes, Microservices, functional application authorization and more, thanks to its single unified policy language.
