I want to create a Windows Docker container.
So, I created a local directory, added all the necessary context files in there and added a Dockerfile to it.
The Dockerfile (in its current state) just defines some variables and a COPY instruction:
# escape=`
FROM mcr.microsoft.com/windows/servercore:20H2
ARG VSPath
ENV VSPath=${VSPath:-"C:\VsBuildInstall\"}
COPY [ "\LocalLayout\", $VSPath ]
...
When I try to build an image from this Dockerfile, I get the following error message:
docker build --rm -t test:latest '.'
Step 1/12 : FROM mcr.microsoft.com/windows/servercore:20H2
---> d7c03b5bcc73
...
Step 9/12 : COPY [ "\LocalLayout\", $VSPath ]
COPY failed: file not found in build context or excluded by .dockerignore: stat LocalLayout\,: file does not exist
According to the documentation, everything in my Dockerfile seems fine.
What am I doing wrong here?
Just for the sake of completeness and because I have no clue where to look for issues in my setup, I’ll add a VS Code screenshot here:
