ViewsNode.js docker can't install npm dependencies
I have this Dockerfile
FROM node:14
WORKDIR /app
COPY package.json .
RUN npm install
COPY . .
EXPOSE 3000
CMD [ "node", "app.mjs" ]
And I can successfully run
docker run hello-world
on my ubuntu 20.10 OS. So I am assuming that docker is installed successfully. But when I tried to run
docker build .
It gives me this error
This is not something with the npm. I can locally install the dependencies without any issue. I assume Dokcer can't access npm registry to pull the npm packages. Something to do with networks I guess.
How do I fix this issue?
This is my code https://github.com/Enuri-Information-Systems/docker-test

Depending on the network configuration it could happen that you run into problems that the container is not able to connect to a server to download data. This can have various reasons and also depends on how you run docker.
One common thing is that your network requires the usage of a proxy. But only having the error message it is not possible to tell what the exact reason in your case is.
One solution to that problem is to specify the network mode. Adding --network host as an option should most of the time work.
So running your build command that way docker build --network=host . should work.
