Docker compose does not work using proxy

Navigation
2

I am creating a docker-compose file to upload a multi-node system. To start testing, I created only one service in this file docker-compose.yml : 

version: '3'

networks:
  production-network:
    driver: bridge

services:
  node1:
    build:
      dockerfile: ./docker/alura-books.dockerfile
      context: .
    image: giulianasilvabezerra/alura-books
    container_name: alura-books-1
    ports:
      - "3000"
    networks:
      - production-network

To build my service, I have Dockerfile below: 

FROM node:latest
MAINTAINER Douglas Quintanilha
ENV NODE_ENV=development
COPY . /var/www
WORKDIR /var/www
RUN npm install 
ENTRYPOINT ["npm", "start"]
EXPOSE 3000

As I use a corporate proxy, I researched how to tell you how to build this image, and I checked that this would be possible with npm config . So I added the commands: 

RUN npm cache clean -f
RUN npm config set proxy http://10.100.5.107:3128
RUN npm config set https-proxy http://10.100.5.107:3128
RUN npm update
RUN npm install

Ond 10.100.5.107 is the ip of my machine that serves as proxy on the 3128 port, without authentication required. The problem is that when I try to run the build, an error occurs because of this proxy configuration: 

docker-compose build

How should I configure the proxy for the build of this image in docker-compose ? I've tried several tutorials, but I did not succeed.

- Machine: Ubuntu 18 - Docker version 18.06.1-ce - docker-compose version 1.15.0, build e12f3b9

I was able to resolve by setting the Docker client [1] : 

{
 "proxies":
 {
   "default":
   {
     "httpProxy": "http://10.100.5.107:3128",
     "noProxy": "*.test.example.com,.example2.com"
   }
 }
}

Follow here for all the steps needed to configure Docker on Ubuntu with the proxy: 

## Removendo versões antigas
sudo apt-get remove docker docker-engine docker.io
sudo apt-get update
## Adicionando a chave GPG oficial do Docker
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
## Adicionando repo do Docker no APT
sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"
sudo apt-get update
## Instala o Docker
sudo apt-get install docker-ce
## Executar Docker sem sudo
sudo usermod -aG docker $(whoami)
## Configurar proxy
sudo mkdir -p /etc/systemd/system/docker.service.d
echo "[Service]
Environment=\"HTTP_PROXY=http://127.0.0.1:3128\"" > /etc/systemd/system/docker.service.d/http-proxy.conf
## Reunicia o docker pra carregar o proxy
sudo systemctl daemon-reload
sudo systemctl restart docker

## Instala o Docker compose
sudo curl -L https://github.com/docker/compose/releases/download/1.15.0/docker-compose-'uname -s'-'uname -m' -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

## Adicionar o proxy no docker client
mkdir ~/.docker/
echo "{
 \"proxies\":
 {
   \"default\":
   {
     \"httpProxy\": \"http://127.0.0.1:3128\",
     \"noProxy\": \"*.test.example.com,.example2.com\"
   }
 }
}" > ~/.docker/config.json
