Alpine image error finding repository/packages while running docker build on local machine

Question

I have a Dockerfile that builds and runs successfully in Azure pipelines (using docker build task)

When I try to run docker build on my local machine with the same file, apk add [package name] fails, seemingly with an issue finding the alpine repository.

 => ERROR [backend-server 3/4] RUN apk add --no-cache       chromium       nss       freetype       freetype-dev       harfbuzz         11.4s

...

The dockerfile uses node:16.13.0-apline3.14

FROM node:16.13.0-alpine3.14 AS build

WORKDIR /usr/src/app

COPY . ./

RUN npm i
RUN npm run build 

WORKDIR /usr/src/app/dist

COPY package*.json ./

RUN npm ci

FROM node:16.13.0-alpine3.14 AS backend-server

      npm

I've tried fetching fetch https://dl-cdn.alpinelinux.org/alpine/v3.14/main/x86_64/APKINDEX.tar.gz and the file exists and downloads correctly on my actual computer. I've also tried running by setting the repository (adding apk add -X https://dl-cdn.alpinelinux.org/alpine/v3.14/main), and setting --allow-untrusted, both with exact same results.

The logs in the pipeline show the fetch succeed.

What are other possible causes of this issue, and why would it be different than running in an azure pipeline?

Answer 1

It's probably an issue with your docker desktop's network configuration. You may need to do a clean reinstall of docker desktop to fix the issue.
