groupadd: GID '0' already exists

[lucasconstantino]

While building the project, some users are reporting the following issue:

groupadd: GID '0' already exists

Apparently, the environment variable GROUP_ID is not coming as expected.

@renatorib has fixed the issue by basically removing any user/group creation. The resulting Dockerfile is as follows:

FROM taller/drupal-node
# Build-time configuration.
# -------------------------
# This is mostly useful to override on CIs.
ARG APP_NAME=drupal
ARG GROUP_ID=1000
ARG USER_ID=1000
# Configure environment.
# ----------------------
ENV APP_NAME=${APP_NAME}
ENV USER_NAME=${APP_NAME}
# ENV GROUP_ID=${GROUP_ID}
# ENV GROUP_NAME=${APP_NAME} USER_ID=${USER_ID} USER_NAME=${APP_NAME}
# Create group and user.
# ----------------------
# RUN groupadd --gid ${GROUP_ID} ${GROUP_NAME}                                                                          \
#    && echo "%sudo ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers                                                           \

@sebas5384 could you have a look at that?

[renatorib]

I guess it might be related to sudo

[lucasconstantino]

@renatorib it might be. But honestly, if we can simply get rid of this it would make the building simpler. We simply need to understand what issues does it solve. As far as I remember, this was only needed for Mac users - but is it really so?

[renatorib]

Yea, I totally agree. And yes, I think that was the only problem I had.

[francisrod01]

I also had this error.
I'm not Mac user. I'm using Debian Linux.

During the installation process, in the file docker-compose.yml..

app:
    extends: meta
    image: taller-chat-app
    build:
      context: ./docker/
      args:
        USER_ID: "$USER_ID"
        GROUP_ID: "$GROUP_ID"
...

I remove args property of taller-chat-app and run make run again,
It works totally fine!
