Docker failed file can not be found

I am having an issue building my docker image. Please find my file below:

I get the following error:

COPY failed: file not found in build context or excluded by .dockerignore: stat BookWooks.OrderApi/Directory.Packages.props: file does not exist

Here is my project structure: enter image description here enter image description here enter image description here

This file does exist and it is in the correct location. I believe I only got this issue after upgrading from .net 7 to .net 8. Would anyone know what is causing this?

Solution

  • I am using: docker build . I am doing this from the folder where the dockerfile is located

    The Dockerfile (at least the one I was able to find on the screenshots) is located inside the BookWooks.OrderApi/src/BookWooks.OrderApi.Web so if you are building it from that folder then docker build context clearly does not have all the folders/files specified in the COPY commands, so from the point of the docker build context the "This file does exist and it is in the correct location." claim is incorrect.

    Either move the docker file to the root of the solution (BookyWooksOnlineStore) and run it from there or run the command from this folder (BookyWooksOnlineStore) and specify path to the docker file, something along the following:

    docker build -f BookWooks.OrderApi/src/BookWooks.OrderApi.Web/Dockerfile .
