This is my dockerfile.

FROM node:10.12.0

RUN npm i -g grpc-tools

RUN useradd --user-group --create-home admin

ENV HOME=/home/admin

WORKDIR $HOME/app

RUN npm config set save-prefix=''

RUN chown -R admin:admin $HOME

USER admin

I tried, but I couldn't solve this problem😭

Reproduction steps

$ docker build

Environment

• docker image: node:10.12.0
• grpc-tools@1.6.6

When running npm under docker, you should pass the option --unsafe-perm. So, your second line should say RUN npm i -g --unsafe-perm grpc-tools.

More specifically, when running npm as root. And by default, any RUN command from a Dockerfile runs as root.

[nicolasnoble]

This Dockerfile works:

FROM node:10.12.0

RUN npm i -g grpc-tools --unsafe-perm
RUN useradd --user-group --create-home admin
ENV HOME=/home/admin
WORKDIR $HOME/app
RUN npm config set save-prefix=''
RUN chown -R admin:admin $HOME
USER admin
