Adding contents of docker file as well:

#Download OS
FROM    resin/rpi-raspbian

# Install CURL
RUN     apt-get update
RUN     apt-get upgrade
RUN     apt-get install --yes wget

# Install Node
RUN     wget http://node-arm.herokuapp.com/node_latest_armhf.deb
RUN     sudo dpkg -i node_latest_armhf.deb
RUN     node -v

# Install npm
RUN     apt-get install --yes npm
RUN     sudo npm install -g npm@latest
RUN     sudo apt-get install --yes build-essential

# Install app dependencies
COPY    package.json /src/package.json
RUN     cd /src; npm install

The last command in this file generates the error.

I'm not familiar with Docker or HypriotOS so probably will not be able to help much.

However, what can be seen is an ENETUNREACH error suggesting that a network is not reachable. epoll doesn't access any networks. What network is not reachable?

Also, is it possible to install other native modules? For example, can buffertools be installed?

[steam0]

Yes, buffertools can be installed.

I am also downloading a ton of packages (wget, node arm, npm, build-essential) from the internet. So ethernet is reachable.

The ENETUNREACH error message is a mystery to me. It might be that HypriotOS does not know of the GPIO pins on the Raspberry Pi?

[fivdi]

And the ENETUNREACH error. Any idea where that's coming from?

[steam0]

I just edited my comment about it 👍

[fivdi]

Does npm install epoll work if called directly from the command line?

epoll doesn't actually know about the GPIO pins on the raspberry pi. It only knows about file descriptors. rpi-gpio knows about them. I don't know if HipriotOS needs to know about GPIO pins.

[steam0]

I updated my Dockerfile to contain

RUN npm install epoll

before I copy the package.json file and execute npm install.

That actually fixed all errors. I don't really know how, but it did. Thank you for your time.

[fivdi]

Is epoll now being installed in a different directory and not below /src? If so, I wonder if the initial problem has something to do with permissions.

[steam0]

This is the updated dockerfile:

#Download OS
FROM    resin/rpi-raspbian

# Install CURL
RUN apt-get update
RUN        apt-get upgrade
RUN     apt-get install --yes wget

# Install Node
RUN     wget http://node-arm.herokuapp.com/node_latest_armhf.deb
RUN     sudo dpkg -i node_latest_armhf.deb
RUN     node -v

# Install npm
RUN     apt-get install --yes npm
RUN     sudo npm install -g npm@latest
RUN     sudo apt-get install --yes build-essential

# Install epoll seperately. Fixes a bug where npm install fails on rpi-gpio
RUN     npm install epoll

# Install app dependencies
COPY    package.json /src/package.json
RUN     cd /src; npm install

# Bundle app source
COPY    app/ /src/
COPY    server.js /src/

# Expose
EXPOSE 3000
CMD     ["nodejs", "/src/server.js]

As we can see, the npm install epoll command is not run from inside /src. So yeah, permission errors might be what caused this problem.

@steam0 I'm going to close this issue as it was configuration issues and I'm unaware of any modifications that need to be made to epoll. If it turns out that epoll does need to be modified, the issue can be reopened.
