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.
Docker Compose

12 Factor: 13 years later
Solutions are many, and could include Docker Compose, VS Code dev containers, Telepresence, Localstack or setting up temporary AWS accounts as a development environment for serverless applications.

Let's write a simple microservice in Clojure
Using Docker Compose to run Postgres and any third-party services locally provides a streamlined and consistent development environment. Developers can define services in a docker-compose.yml file, which enables them to configure and launch an entire stack with a single command. In this case, Postgres is encapsulated within a container with predefined configurations. Docker Compose also facilitates easy scaling, updates, and isolation of services, enhancing development efficiency and reducing the setup time for new team members or transitioning between projects. It encapsulates complex configurations, such as Postgres' performance monitoring and logging settings, in a manageable, version-controlled file, simplifying and replicating the service setup across different environments.

Docker compose, orchestrating and automating services
“Compose simplifies the control of your entire application stack, making it easy to manage services, networks, and volumes in a single, comprehensible YAML configuration file. Then, with a single command, you create and start all the services from your configuration file.” - Docker documentation

This foundation now opens the door to even more powerful concepts. You can explore more advanced concepts such as container networking, streamlining the management of complex applications with Docker Compose, and how to make your application data persistent using volumes.

Use same Dockerfile for Dev & Production
In many projects that are containerized, especially in cases where development is also done locally with docker-compose, teams often have two Dockerfiles, 1 for Development, the other for Production. If you happen to have multiple environments like pre-prod, staging and so on, some teams could have different Dockerfiles for these environments.

Can I scale my dockerized Flask solution with Kubernetes?

☸️ Kubernetes: From your docker-compose file to a cluster with Kompose
As stated on their homepage, with Kompose, you can now push the same file to a production container orchestrator!. The tool definitely covers a wide range of Kubernetes features, among which these are meaningless locally but crucial for kubernetes :

Single docker compose stack on multiple hosts. But how?
K3s is a small, open source, no nonsense, distribution of Kubernetes. I think you'll find it just as easy to setup as Swarm. The challenge will be that Kubernetes has an entirely different API compared to Docker/Docker Compose. This can be mitigated by a tool called kompose, but using this will limit what you can do on Kubernetes.
-
Should I be using a unified Docker-Compose.yml?
Although I recently moved my own services from docker compose to kubernetes using https://kompose.io/ and now the only thing I run with docker compose, currently, is my private docker registry but everything including in kube, are always in their own folders.

I haven't run into the need to do that, but there is the Kompose project that exists to help with the conversion (https://kompose.io/)!

If I pull a docker image, can that image file be uploaded to a kubernetes cluster and it will work right away?
Compose claims to do that. https://kompose.io and https://kubernetes.io/docs/tasks/configure-pod-container/translate-compose-kubernetes/
