Docker on ubuntu--groups: cannot find name for group

[hanm2019]

Description

I build the docker image in a machine named A and then transfer the image to another machine named B and then run it with docker run --rm -it -u $(id -u ${USER}):$(id -g ${USER}) -v $(pwd)/flow:/OpenROAD-flow-scripts/flow openroad/flow-$OS_NAME-builder

get:

groups: cannot find name for group ID 1003
I have no name!@9a41a4f15c50:/OpenROAD-flow-scripts$ echo $USER

I have no name!@9a41a4f15c50:/OpenROAD-flow-scripts$ whoami
whoami: cannot find name for user ID 1003
I have no name!@9a41a4f15c50:/OpenROAD-flow-scripts$ id
uid=1003 gid=1003 groups=1003

Suggested Solution

update the docker start cmd

from

docker run --rm -it -u $(id -u ${USER}):$(id -g ${USER}) -v $(pwd)/flow:/OpenROAD-flow-scripts/flow openroad/flow-$OS_NAME-builder

to

docker run --rm -it -u $(id -u ${USER}):$(id -g ${USER}) -v $(pwd)/flow:/OpenROAD-flow-scripts/flow  -v /etc/passwd:/etc/passwd:ro -v /etc/group:/etc/group:ro openroad/flow-$OS_NAME-builder:latest

this is just for ubuntu :)

@hanm2019
How you installed OpenROAD-flow-scripts in docker mode?
Did you followed this instruction https://openroad-flow-scripts.readthedocs.io/en/latest/user/BuildWithDocker.html ?

[vijayank88]

Before running docker command set following in terminal if default steps used for installation:
export OS_NAME=centos7

[hanm2019]

Yes, I install it in ubuntu

[hanm2019]

I run in ubuntu OS, so I set the OS_NAME to ubuntu20.04 by

export OS_NAME=ubuntu20.04

[vijayank88]

After export OS_NAME=ubuntu20.04 did you followed below steps for installation?

git clone --recursive https://github.com/The-OpenROAD-Project/OpenROAD-flow-scripts
cd OpenROAD-flow-scripts
./etc/DockerHelper.sh create -target=dev -os=$OS_NAME
./etc/DockerHelper.sh create -target=builder -os=$OS_NAME

Otherwise docker default built with centos7 OS

./etc/DockerHelper.sh create -target=builder -os=$OS_NAME

Yes, and my host OS is ubuntu18.04, but I config the OS_NAME to ubuntu20.04 and after running

./etc/DockerHelper.sh create -target=dev -os=$OS_NAME
./etc/DockerHelper.sh create -target=builder -os=$OS_NAME

I build the image successfully.

@hanm2019 is this on a machine which has a networked login? e.g. the passwd and group files are stored on the network?

[hanm2019]

I build the docker image in a machine named A and then transfer the image to another machine named B. the groups: cannot find name for group ID 1003 is shown when I run the docker on machine B.

[hanm2019]

the image is by1906007/flow-ubuntu20.04-builder:latest

[rovinski]

Are the passwd and group files different between machines A and B? It doesn't really feel like mounting the passwd and group files is the right solution here - a vast majority of users will never encounter this issue...

[hanm2019]

Yeah, the passwd and group files are different between machine A and B.

[vijayank88]

I build the docker image in a machine named A and then transfer the image to another machine named B. the groups: cannot find name for group ID 1003 is shown when I run the docker on machine B.

@hanm2019 above should be part of your issue description. So it will easy to understand the problem and resolved quickly.
Without proper description it leads to long conversation.

Is mirror copying will work ?
