You’re absolutely right
In fact, the search command is rarely used and almost never used
But a piece of software that does this and it doesn’t work is a very bad checkup
And search is friendly for beginners
I agree of course. I guess it is not a priority for the developers and testers anymore and it looks like they don’t have an automatic test for it before a new release.
I could test that search works with Docker 20.10.7 on my WSL machine (on which I have a strange login warning) and it doesn’t work with 20.10.8 on my Mac neither on a Linux laptop with Docker 20.10.10.
This is intresting since @meyay mentioned it doesn’t works for him with 20.10.9.
I thought we already agreed the error is raised when a user is logged in (after docker login), and does not effect users that are not logged in.
On top of that: docker search is not particularly usefull for anything. I don’t see myself creating an automatism that relies on the output of docker search to create a container from the search result…
You are right, but it doesn’t change the fact it should work 
I think peope could just let it go if they knew it is an officially abandoned feature which will be removed in the next release.
