Yarn install in Docker image

Question

I have written a Docker file and I am installing Yarn in the container. But the yarn install/npm install doesn't seem to work. But when I run the yarn install outside the Docker file, it works completely fine. I have done the required proxy settings and everything but still no success.. Not sure why it's failing.

FROM nexus.corportation.com:8221/nodejs:latest
ARG SRCDIR

RUN mkdir /home/nodejs/app
RUN chown -R nodejs:nodejs /home/nodejs
#Ensure correct ownership
COPY $SRCDIR /home/nodejs/app/
USER root
RUN chown -R nodejs:nodejs /home/nodejs/app
#our user setup in the base container
USER nodejs

#Now using yarn
RUN /bin/bash -c 'source $HOME/.bashrc;cd app;  yarn install'
ENTRYPOINT ["node", "app/javascript/index.js"]
EXPOSE 8080

But I get the following error:

error An unexpected error occurred: "https://nexus.corportation.com:8221/nexus/repository/npm-all/@xyz%2flt-navigator: tunneling socket could not be established, cause=getaddrinfo ENOTFOUND http http:80".

This works fine outside Docker. I have tried to set the HTTP proxy along with Docker build but still not working.

Answer 1

Try mentioning the proxy in the docker file. Check what's the default docker network its using, that network should have access to the repo. ENV http_proxy ENV https_proxy ENV HTTP_PROXY ENV HTTPS_PROXY
