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.

D2 is now open source – a new, modern language that turns text to diagrams
1. not currently, but it's on the roadmap!
2. with any integration, if there's enough demand, we'll do it. Once we add interactivity to diagrams, it should be trivial to emulate. However I should mention that Simon Brown (the creator of C4) has his own DSL for C4 https://github.com/structurizr/dsl)! We have no intention of competing with it.
3. Currently the options to tune are limited. The Terrastruct app has granular layout control via drag-and-drop, and we're working to bring some of that to native/open-source.

How is your time spent in the architecture role?
It's really just an evolution of the original Structurizr for Java library that I built 5+ years ago. Some people really liked the ability to create a model+views using a programming language (ports are now available for .NET, PHP, Python, TypeScript, etc), but many thought it was silly. So I've always wanted to do something "text-based", but I wanted to do "models as code" rather than "diagrams as code". The lockdown in 2020 gave me some time to do this, and the DSL is really just a thin wrapper on that original Java library. Being a wrapper for the Java library provides a way for you to create parts of your model via scripts (Groovy, Kotlin, JRuby) or by mixing the DSL and code. This creates opportunities for manually defining a high level model, and then perhaps inserting a deployment architecture that's automatically generated by parsing AWS/Azure/Terrform/etc.

Structurizr – Diagrams as Code
Some helpful URLs, IMHO
https://structurizr.com/dsl?example=amazon-web-services (hover over the diagram and press the play icon to trigger the "animation" referenced in the DSL)
https://structurizr.com/products as for "which parts are free vs paid"
https://github.com/structurizr/dsl#readme (one of several repos, but unclear which is the "main one") they all seem to be Apache 2 licensed

I'm just serving as lazyweb bot, I haven't used this product(service?) before

Architecture as Code with C4 and Plantuml
Thanks for structurizr DSL. I'm a big fan of C4 and plantUML. I'll definitely have a look at https://github.com/structurizr/dsl.

Software to build a visual representation of the solution?
The C4 model and the Structurizr DSL (demo) are pretty much designed to do exactly this. Disclaimer: I'm the author of both.
-
Reading up on C4 Model...how would you document related systems and repos without repeating yourself?
Create a system landscape, plus a drill-down for each system. In this option you create a new repo in which you define your system landscape - i.e. all of the people and software systems, plus their interactions. In the system1 repo, you extend this model to add the internal details, diagrams, and docs specifically for system1. Repeat for system2 and system3. With this approach, you would see that system1 (and system1.serviceX) interacts with system2, but you wouldn't see system2.serviceY, since that's an implementation detail of, and internal to, system2. The Structurizr DSL has been designed to work for this use case with the "workspace extension" feature, see https://github.com/structurizr/dsl/tree/master/docs/cookbook/workspace-extension for more details.

A visual C4 model tool for your team
This (icepanel.io) is just a graphical editor for C4 Model diagrams.
The actual standard (if you can call it that, because it is quite light weight, and that is a good thing) is open source as far as I know.
This means that you can create C4 diagrams with PlantUML [0] or using the C4 specific DSL [1].
[0] - https://github.com/plantuml-stdlib/C4-PlantUML
[1] - https://github.com/structurizr/dsl
-
Alternatives to c4 model?
With this in mind, the Structurizr DSL provides a way to create a model as code, which can then be rendered using tooling of your choice. The Structurizr renderer is one option, but there are others, and you can build your own to meet the style that you're looking for. See structurizr.org - Rendering tools for more.
-
Scripting support added to the Structurizr DSL
The Structurizr DSL now provides a way to run scripts written in Groovy, Kotlin, Ruby, and JavaScript, via the new !script keyword. This gives you access to the underlying Structurizr for Java workspace, for when you need to do something not supported by the DSL.

I would like to make calls to the K8s API server from within a Java app that is running in a pod. How would I authenticate it to do so?
While that is true I‘d like to suggest taking a look at this client: https://github.com/fabric8io/kubernetes-client
-
Does Fabric8io K8s java client support patch() or rollingupdate() using YAML snippets?
I am trying to program the patching/rolling upgrade of k8s apps by taking deployment snippets as input. I use patch() method to apply the snippet onto an existing deployment as part of rollingupdate using fabric8io's k8s client APIS.. Fabric8.io kubernetes-client version 4.10.1I'm also using some loadYaml helper methods from kubernetes-api 3.0.12.

Pod labeling not possible from within pod using Kubernetes on Docker-EE
This approach works fine on our DIND-Kubernetes environment. However, when tried to port the deployment onto a Docker-EE Kubernetes environment we ran into trouble because the command kubectl label pod generates a run time error which is completely misleading (also see https://github.com/fabric8io/kubernetes-client/issues/853).

Using Java annotation processor in Scala
To be specific, I am trying to use https://github.com/fabric8io/kubernetes-client/tree/master/crd-generator in scala code. If it is only duplicating one class or so, that seems manageable. But if I need to rewrite everything I am less confident
- Is 6 LPA worth it to work at a startup from 9 AM to 8 PM?
-
Creating scalable microservices for practice?
In terms of spinning up and managing everything, like, the stuff that's not Java apps. But some of the old fabric8 work - the predecessor to jKube - provides Java APIs and utilities to doing things like writing kubernetes operators in Java. Check out the kubernetes-client project. A lot of people never even learn about kubernetes operators, and just think "I have a service, la la la" plug their ears and then assume there will be some magic operational team that will deploy some service mesh app to solve all their problems.

How can I deploy a containerized application from code?
Fabric8 is a very good Solution. I played also with k8s provided solution but especially custom resource definitions are a hell. I can recommend fabric8 it’s also used in operators like strimzi https://github.com/fabric8io/kubernetes-client
