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.

Quadlets might make me finally stop using Docker-compose – Major Hayden
Whole quadlets are cool, this just means me miss the rkt runtime. https://github.com/rkt/rkt It integrated with systemd properly quite a while ago.

Docker containers usually still reachable even if bound to 127.0.0.1
rkt (and many other container solutions) was introduced after docker was released and became popular... they even mentioned docker's shortcomings as a motivation for the project creation [0]. It had all the same problems as other replacement software: there were plenty of bugs and missing features, documentation was limited, and there are no community to help you (the announcement explicitly mentions "prototype quality release"). None of those would be fatal if it was significantly better than docker, but it was not -- it was basically the same functionality. So almost no one made the switch. It is closed now [1]
And why "rkt"? There were much better alternative container runtimes. For example Sylabs Singularity [2] -- container-as-a-file, instant mounting, etc... I wish more people knew about it.

Using Docker to Containerize Laravel Apps for Development and Production
Think of Docker as the AWS of the container world in terms of popularity, there is another container platform called rocket (rkt) which can be considered something like Vultr in this analogy.

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.
