ECONNREFUSED 127.0.0.1:80

[GitProdEnv]

Summary:

I am running the reverse-proxy/nginx example with nginx ssl (https://github.com/verdaccio/docker-examples/tree/master/reverse_proxy/nginx/relative_path) in a development environment.
Publishing is working as expected, but I have a problem when I want to build a new docker image and use npm install within my Dockerfile.

Reproduction:

Running the reverse-proxy/nginx example
docker-compose -f docker-compose_ssl.yml up --build --force-recreate
and
npm publish

Result: I can go to localhost and see my published package. I also can npm install it via the command line.

After that, that's my simple Dockerfile to build:

FROM node:13.3-alpine

WORKDIR /app
COPY package.json .
RUN npm install --only=prod --registry http://localhost
COPY . .

CMD ["npm", "start"]

Error:

I am already spending days because of that problem. I want to use verdaccio as a proxy for building new docker images. Thanks for your help.

I solved it with prepending docker build with --network="host"
