Error creating a docker container with crops/poky

[sgordon777]

I am trying to create a docker container following these instructions:

https://github.com/crops/poky-container/blob/master/README.md

I am quite new to both yocto-build and Docker. My Host is Ubuntu 22.04. My Command:

docker run --rm -it -v /home/sgordon777/dev/yocto:/workdir crops/poky --workdir=/workdir

This command fails with:

"The uid:gid for "/workdir" is "0:0". The uid and gid must be non-zero. Please check to make sure the "volume" or "bind" specified using either "-v" or "--mount" to docker, exists and has a non-zero uid:gid."

I have checked and my local director (~/dev/yocto) is:
-present
-owned by my user, not root

I have this problem in both poky-container and extsdk-container. I left a comment in extsdk-container that might work for you, too crops/extsdk-container#10 (comment)

Looking closer at things, these days it might actually be easier to use this docker image and build poky from it: https://github.com/crops/yocto-dockerfiles/blob/master/dockerfiles/ubuntu/ubuntu-18.04/ubuntu-18.04-base/Dockerfile

crops/poky seems to do some gymnastics to make the generated files visible to the host, but I don't think those are needed with modern rootless docker and podman.
