When running docker image it shows error cannot find name for group ID 1000

I am using Ubuntu in virtual machine. I have cloned my git repository in a directory in /home/Yocto_Dev using git clone command.

Below are the commands executed.

1. git clone
2. docker build -t ubuntu-yocto-kirkstone
3. docker run -it --name my_container -v /home/chandra/.ssh/root/.ssh -u "$(id -u):$(id -g)"ubuntu-yocto-kirkstone /bin/bash

command throw below error

**groups: cannot find name for group ID 1000
I have no name!@72cd4f3f84bd:/$** 

Note: Ubuntu machine and Docker container user ids are not same.

My goal is: To copy local SSH keys inside docker container and clone the repository inside docker container.

You need to add your user to the docker group

sudo usermod -aG docker yourusername

You can refresh the group by running the command or logoug and log back in again

sudo `newgrp docker`

Hope this helps.
