build error

Describe the bug
./build.sh --type single --zip /home/centos/SAS_Viya_deployment_data.zip --addons "auth-demo"

groupadd: invalid group ID 'docker'
The command '/bin/sh -c groupadd --gid ${DOCKER_GID} docker' returned a non-zero code: 3

[Mapreduce2]

We worked around the problem by commenting out the following

RUN groupadd --gid ${DOCKER_GID} docker
RUN useradd --uid ${USER_UID}
--gid ${DOCKER_GID}
--create-home
--shell /bin/bash
sas

and replacing it with

RUN groupadd -g ${DOCKER_GID} docker && useradd -m -u ${DOCKER_GID} -g docker sas

However, why does the existing code fail? I was not able to answer that.
