internet connection issue while creating Docker Image

Question

I am trying to create a simple docker image in AWS EC2.

I have the following Dockerfile.

FROM node:12-alpine

RUN apk add --no-cache build-base gcc autoconf automake libtool zlib-dev libpng-dev nasm

RUN mkdir -p /home/project/website/node_modules && chown -R node:node /home/project/website

WORKDIR /home/project/website

COPY /package*.json ./

USER node

RUN npm cache verify

RUN npm install

COPY --chown=node:node . .

RUN chmod +x wait-for.sh

RUN chmod -R 0755 /home/project/website/src/views/

EXPOSE 8000

when I try to build by this following command docker-compose build

I got the following output

Step 2/12 : RUN apk add --no-cache build-base gcc autoconf automake libtool zlib-dev libpng-dev nasm

and I have already created it for the first time and everything was running successful, but I have changed some paths on my docker file and I have removed all containers, images, volumes... but this time I got this error.

Try docker build with `--network host` flag. Refer to docs at : https://docs.docker.com/network/host/ . If your host is behind a proxy server, then you need to add proxy server in the docker build command. — Amit kumar, Sep 27 '20 at 15:16

I solved the problem by the following commands

pkill docker
iptables -t nat -F
ifconfig docker0 down
brctl delbr docker0
docker -d

Here is the original answer

My docker container has no internet
