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.

Dagger: a new way to build CI/CD pipelines
I'm not touching anything Docker anymore.
Here's the scenario: you're the unfortunate soul who received the first M1 as a new employee, and nothing Docker-related works. Cue multi-arch builds; what a rotten mess. I spent more than a week figuring out the careful orchestration that any build involving `docker manifest` needs. If you aren't within the very fine line that buildx assumes, good luck pal. How long has `docker manifest` been "experimental?" It's abandonware.
Then I decided it would be smart to point out that we don't sign our images, and so I had to figure out how to combine the `docker manifest` mess with `docker trust`, another piece of abandonware. Eventually I figured out that the way to do it was with notary[1], another (poorly documented) piece of abandonware. The new shiny thing is notation[2], which does exactly the same thing, but is nowhere near complete.
At least Google clearly signals that they are killing something, Docker just lets projects go quiet.
How long before this project lands up like the rest of them? Coincidentally, we were talking about decoupling our CI from proprietary CI, seeing this was a rollercoaster of emotions.
