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.

I faced this issue.

I found that rootless docker does not solve all user permission issues since the user in the container is root, and some applications do not allow to be run as root (bitbake for example).
