Resin nmcli permission denied




I am trying to make nmcli run inside the app container, so I can change some network settings.

# base-image for node on any machine using a template variable,
# see more about dockerfile templates here:
# and about resin base images here:
# Note the node:slim image doesn't have node-gyp
FROM resin/%%RESIN_MACHINE_NAME%%-node:6-slim

# Enable systemd init system in container

# use apt-get if you need to install dependencies,
# for instance if you need ALSA sound utils, just uncomment the lines below.
#RUN apt-get update && apt-get install -yq \
#    alsa-utils libasound2-dev && \
#    apt-get clean && rm -rf /var/lib/apt/lists/*

#RUN apt-get update && apt-get install network-manager

RUN apt-get update && apt-get install network-manager && \
	apt-get clean && \
	systemctl mask NetworkManager.service

WORKDIR /usr/src/app

COPY . .

RUN ["chmod","+x","nmcli"]

#CMD ./nmcli

# Defines our working directory in container
#WORKDIR /usr/src/app

# Copies the package.json first for better cache on later pushes
COPY package.json package.json

# This install npm dependencies on the build server,
# making sure to clean up the artifacts it creates in order to reduce the image size.
RUN JOBS=MAX npm install --production --unsafe-perm && npm cache clean && rm -rf /tmp/*

# This will copy all files in our root to the working  directory in the container
COPY . ./

# server.js will run when container starts up on the device
CMD ["npm", "start"]

CMD ./nmcli

#CMD ["nmcli","--nocheck", "connection","up","resin-wifi-02"]

I try to set RUN chmod +x nmcli, but it still gives me the error:

23.01.18 04:34:15 (+0100) /bin/sh: 1: ./nmcli: Permission denied

What am I doing wrong? Thanks for help



would you like to check this sample project out?

Is there a chance you are missing this?




this is what I used. I have put the nmcli wrapper file into the folder. That is why I am confused.

I even tried to use this project standalone on a raspberry pi. I get errors:

It worked with and edited slimmed down version
