Docker as a technology is a misguided mess but it is an effective tool.
Podman is a much better design that solves the same problem.
Containers can be used well or very poorly.
Docker makes it easy to ship something without knowing anything about System Engineering which some see as an advantage, but I don’t.
At my shop, we use almost no public container images because they tend to be a security nightmare.
We build our own images in-house with strict rules about what can go inside. Otherwise it would be absolute chaos.
I’ve come to realize that bluesky already had all lot of what I’m happy to not see on masto. Good that there is a place for it to exist without me.
That content is also probably what the majority of people like about it.
