"Many attempts can be found on the internet, none of which works well. There is no API to list images with dates"
http://portainer.io/ seems to be able to do it, docker images lists it... I mean, I don't want to call bullshit without knowing the full story, but...
"So, the docker guys wrote a new filesystem, called overlay"
https://github.com/torvalds/linux/commit/e9be9d5e76e34872f0c... written in 2014 by the linux kernal team / Linus, but OK cool story
"It affects ALL systems on the planet configured with the docker repository"
OK, this is why people use AWS' container repo, or they use the open source software and maintain their own repo... this happens with any of the public repo services, and it was 7 hours.
"The registry just grows forever"
S3 is a supported backend, highly would advise anyone running their own repo to use it (or have a similar expanding-space story). There's also a config flag for the repo to allow removing images. Obviously wouldn't want to use this if you're hosting a public repo but internally, go for it, it's off by default, seems sane enough.
"Erlang applications and containers don’t go along"
I'm certain that people are running erlang containers successfully.
"Docker is a dangerous liability that could put millions at risk. It is banned from all core systems."
Daily FUD allowance exhausted.
I guess the tone of this article really bugged me because there's obviously a point to be made from this experience that running Docker is more difficult & error prone than it should be. And maybe it wasn't a great fit for this company culture. But this article crossed the "we didn't have a good experience, therefore, it's BS software" line, and frankly, that attitude may very well have been to blame for the lack of success just as much as docker's shortcomings were...
