docker compose not finding my files

Question

Docker is telling me it cant find the specified file. Is my context wrong? My folder structure is as follows.

root
  - docker
    - docker-compose-service.yml
  - service
    - DockerFile
  Nuget.config

Inside my docker-compose-service.yml file I have

build:
  context: .
  dockerfile: ../service/DockerFile

I run from the root folder the following command

docker-compose -f docker/docker-compose-service.yml up --build

It can find the Dockerfile as it runs the code but fails on a line inside the dockerFile which is

COPY NuGet.config .

The error is

failed to build: COPY failed: stat /var/lib/docker/tmp/docker-builder408021827/NuGet.config: no such file or directory

What am I doing wrong? I played around with the context and dockerFile location but then it couldn't find the DockerFile

---

Hmm so if I run the command from the docker folder and change the docker-compose-service.yml file to be

context: ../
dockerfile: service/DockerFile

That seems to work

Answer 1

The path specified in your docker file sets the context as the parent folder of the compose file. In order to make it work, you need to either:

1. Change the context to .
2. Change the path to NuGet.config to also contain the current folder name: root/NuGet.config

I would recommend the first approach as from your question I don't see any reason you would want to refer to the parent folder.
