Docker build pull access denied, repository does not exist or may require

Question

I am trying to generate a Docker Image without using Visual Studio. I am in the project folder and I execute from windows 10 admin command line docker build . I can't figure out how to make this work.

This is my dockerfile:

#See https://aka.ms/containerfastmode to understand how Visual Studio uses this Dockerfile to build your images for faster debugging.
FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-buster-slim AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-buster AS build
WORKDIR /src
COPY ["src/App.Web/App.Web.csproj", "src/App.Web/"]
RUN dotnet restore "App.Web.csproj"
COPY . .
WORKDIR "/src/App.Web"
RUN dotnet build App.Web.csproj -c Debug -o /app

FROM build as debug
RUN dotnet publish "App.Web.csproj" -c Debug -o /app

FROM base as final
WORKDIR /app
COPY --from=publish/app /app .
ENTRYPOINT ["dotnet","App.Web.dll"]

Answer 1

You have stages called base, build, and debug. Then in the final stage you have:

COPY --from=publish/app /app .

When docker can't find the stage with that name, publish/app, it tries to find that image, which doesn't exist. I'm guessing you want to copy from the build stage, e.g.

COPY --from=build /app .

thanks I see it now. I changed the name without understanding what I did – Depersonalization

FROM node:16 as builder, I was missing (as builder) . thanks – Imbecilic

Thanks! I simply forgot to name a stage, the Docker error message was not clear enough, and I ended up here – Unhallowed

Answer 2

Are you logged in? Try with docker login and then execute docker build once again

As I can see here aspnet in docker hub the repository that you intent to use has been renamed. Use the following instead

from mcr.microsoft.com/dotnet/aspnet:3.1-buster-slim

Repositories have been renamed and a similar issue can be found here similar issue

Thanks for your suggestion. This did not fix the issue, as it states in the link " Updates will continue to be made to supported tags in the old repository locations for backwards compatibility. " But it is valuable knowledge to know there is a new location – Depersonalization
