investigate mapping docker user UID to host user UID

So I set up a new user with UID 1007, and then added --user $UID:$GID to docker command. It all seems to work, except I get this on the prompt:

I have no name!@950428eb105c:/home/cbrake2/yoe-distro$

which is a little unseemly.

[kraj]

this message is displayed when the current user's uid and gid from docker host is not mapped inside the container's /etc/passwd

I'll try fixuid next unless there is something better.

[kraj]

fixuid will violate the static container concept. So if we can live with "I have no name!" then it would be my preference since we do not use the container interactively as much.

ok, that works for me -- I'll test a build under a different user just to make sure it works, and then commit.

[cbrake]

test build as another user worked fine, so I think this is a good solution. I pushed the change, and closing issue.

Just ran into an issue where if we fetch sources over git using ssh for authentication, we get messages like:

Failure expanding variable SRCPV, expression was ${@bb.fetch2.get_srcrev(d)} which triggered exception FetchError: Fetcher failure: Fetch command failed with exit code 128, output:

No user exists for uid 1001

In this case, the host UID was 1001, instead of 1000.

So, the user mapping we have now works for builds that have only OSS, but for project builds, we typically need to fetch sw using git+ssh.

Have you tried adding user to the docker group?

https://docs.docker.com/install/linux/linux-postinstall/
$ sudo usermod -aG docker $USER
then change docker directory ownership and permissions
$ sudo chown "$USER":"$USER" /home/"$USER"/.docker -R
$ sudo chmod g+rwx "$HOME/.docker" -R
