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.

[TechStory]: Migrating services and databases from an OpenShift (or K8s) cluster to another
My first experience with OpenShift was with a task which was kind of a heavy task, I didn't know anything about OpenShift or K8s! but I was in charge of migrating resources from a cluster to one another! (twice!)

DevOps Tooling Landscape
OpenShift is a container platform from Red Hat that's built on top of Kubernetes. It offers additional features like built-in CI/CD pipelines, enhanced security, and support for multiple programming languages and frameworks.

My director is mad that I accepted another internal position for a 26% raise when he was told he could only give me a 10%
At your own pace, jump into orchestration using a Kubernetes distribution out there; but really, only do that fairly late in the game (e.g. OpenShift). Sadly, it's quite a jump from containers to orchestration, and there is no "smooth" in-between. Maybe as a prelude, you can look into etcd configuration clusters and Ceph storage clusters first, e.g. using a bunch of VMs on your machine, or a few Raspberry Pis. There are plenty of occasions to pinch your fingers with those, and thus valuable lessons to be learned :-)

OpenShift in a disconnected environment using vCenter - starting from nothing
Part of my job is to help document and assist with getting environment running offline, including OpenShift. While I don't use vSphere the general process is the same, while individual platforms may require different commands the concepts are all the same. Using docs.openshift.com you can find comprehensive guides in how you setup each platform Openshift supports "disconnected". But do realize that not all organizations agree on the exact definition of what disconnected means so you may need to adjust based on what you need. Some allow "sneaker net", others requires you to use old fashioned DVDs to bring all data onsite etc.

Best documentation/discovery process and/or tool for an existing Openshift environment?
You want to be able to rebuild your clusters in case of a disaster, so, any time you install anything, export the yaml. And read https://docs.openshift.com/ for every new version.

Release Radar · April 2024 Edition: Major updates from the open source community
It's like Prometheus, but for logs. Okay it's not really to do with the Norse or Greek gods, instead Loki is a horizontally-scalable, highly-available, multi-tenant log aggregation system inspired by the open source project Prometheus. Built by Grafana Labs, Loki is designed for ease of use. Instead of indexing the contents of the logs, Loki provides a set of labels for each log stream. The latest update includes query acceleration with Bloom filters, native OTel support, Helm charts, and more. Check out the changelog for all the major changes and deprecations.

The power of the CLI with Golang and Cobra CLI
Just to give an example of the power of Go for CLI builds, you may have already used or at least heard of Docker, Kubernetes, Prometheus, Terraform, but what do they all have in common? They all have a large part of their usability via CLI and are developed in Go 🐿.

On Implementation of Distributed Protocols
Distributed system administrators need mechanisms and tools for monitoring individual nodes in order to analyze the system and promptly detect anomalies. Developers also need effective mechanisms for analyzing, diagnosing issues, and identifying bugs in protocol implementations. Logging, tracing, and collecting metrics are common observability techniques to allow monitoring and obtaining diagnostic information from the system; most of the explored code bases use these techniques. OpenTelemetry and Prometheus are popular open-source monitoring solutions, which are used in many of the explored code bases.

Golang: out-of-box backpressure handling with gRPC, proven by a Grafana dashboard
Setting up monitoring for a system, especially one involving GRPC communication, provides crucial visibility into its operations. In this guide, we walked through the steps to instrument both a GRPC server and client with Prometheus metrics, exposed those metrics via an HTTP endpoint, and visualized them using Grafana. The Docker-Compose setup simplified the deployment of both Prometheus and Grafana, ensuring a streamlined process.

Monitoring, Observability, and Telemetry Explained
Alerting and Notification: Select a tool with flexible alerting mechanisms to proactively detect anomalies or deviations from defined thresholds. Consider asking questions like "Does this tool offer customizable alerting options and support notification channels that suit our team's communication preferences?" A tool like Prometheus provides robust alerting capabilities.
