I am deploying some node.js services to a corporate system within docker containers. My Dockerfiles for these services are very basic, with the exception that I am setting the proxy environment variables:
FROM node:4.2.3
ADD . /src
WORKDIR /src
ENV http_proxy http://proxy.gc.corp.com:8888/
ENV https_proxy http://proxy.gc.corp.com:8888/
ENV HTTP_PROXY http://proxy.gc.corp.com:8888/
ENV HTTPS_PROXY http://proxy.gc.corp.com:8888/
RUN npm install --production
EXPOSE 3000
CMD npm start >> /log/eva_web_api
When I build my image from this file I receive the following error from NPM:
error on last attempt: Error: tunneling socket could not be established, cause=getaddrinfo ENOTFOUND proxy.gc.corp.com proxy.gc.corp.com:8888
However when I perform the NPM install on the host machine (which has Node.js installed as well as Docker), the NPM install performs as normally and completes with no issue. One the host I have those same ENV variables set as I define in my Dockerfile.
Anyone have any ideas as to what is going on here, I have a ticket open with my networking team in charge of the proxy but they are yet to be any help.
