Hi: When I try to build starlingx image, i have some problems and can't resolve it. I follow the following doc to build our image. https://wiki.openstack.org/wiki/StarlingX/Developer_Guide#Build_the_CentOS_M... At setup building Docker Container, step 7: make build At building process, executing the below command will fails. RUN useradd -r -u $MYUID -g cgts -m $MYUNAME && ln -s /home/$MYUNAME/.ssh /mySSH Error is useradd: UID 0 is not unique. I try to add flag -o into useradd, so can pass this step. But at build packages, step 4 will fails. build-pkgs --serial The main reason of this step is that lighttpd startup fails. I also try other method to build it. For example: at /../stx-tools/Makefile file, delete -build-arg MYUID=$(UID) (at my host machine, i directly use root account) So, command "make build " can pass, but non-root account will be lack of permission to do anything inside container. Anybody have ideal to this issue. Thanks Dehao
