And I have one directory in bin directory anycodings_visual-studio-2019 that name is app.publish.

And my Dockerfile is like below:

#Depending on the operating system of the host machines(s) that will build or run the containers, the image specified in the FROM statement may need to be changed.
#For more information, please see https://aka.ms/containercompat

FROM mcr.microsoft.com/dotnet/framework/aspnet:4.8-windowsservercore-ltsc2019
ARG source
WORKDIR /inetpub/wwwroot
COPY bin/app.publish .

After I run below command to build image anycodings_visual-studio-2019 from this docker file

docker build -t soroshsabz/testcoreservice .

I got the below error

My question is why I got this error? and how anycodings_visual-studio-2019 to resolve it?

I use Docker Engine Community 20.10.6 on anycodings_visual-studio-2019 Windows 10 20H2 19042.964

I see Docker - failed to compute cache key: anycodings_visual-studio-2019 not found - runs fine in Visual Studio and anycodings_visual-studio-2019 some internal links, but does not find any anycodings_visual-studio-2019 useful things.

I am binging my problem and find some same anycodings_visual-studio-2019 problem like Dockerfile can’t anycodings_visual-studio-2019 copy specified local directory & file or anycodings_visual-studio-2019 Windows Docker Dockerfile COPY file inside anycodings_visual-studio-2019 folder.

Answers 1 : of Docker build failed to compute cache key

Thanks to BMitch, I found my problem. anycodings_dockerfile The problem is the dockerignore file anycodings_dockerfile contains some pattern that must not anycodings_dockerfile match with COPY files name.

My problem is the patterns inside the anycodings_dockerfile dockerignore file is matched wrongly anycodings_dockerfile with bin/app.publish. To resolve my anycodings_dockerfile problem I just change the pattern in anycodings_dockerfile dockerignore.

Answers 2 : of Docker build failed to compute cache key

This might be of some help to others:

I am building a .NET Core application anycodings_dockerfile with a dockerfile and had been doing anycodings_dockerfile some renaming. I got the "failed to anycodings_dockerfile compute cache key" error, because the anycodings_dockerfile filenames in the dockerfile no longer anycodings_dockerfile matched the new names I had given to the anycodings_dockerfile targeted files.

Once I fixed the naming in the anycodings_dockerfile dockerfile, everything worded as anycodings_dockerfile expected.

What does Workdir do in Dockerfile?

Where should Dockerignore file be?

What is difference between ADD and copy in Dockerfile?

What is a Docker build context?
