service parsedmarc' failed to build: COPY failed

[HardTarget411]

When install dmarc-visualizer, I get the following error.

Error: Service 'parsedmarc' failed to build: COPY failed: file not found in the build context or excluded by .dockerignore: stat parsedmarc.ini: file does not exist

Installed on vanilla ubuntu 20.04. Here is the video I followed: https://www.youtube.com/watch?v=a9CUTfzADLQ

I guess you did not configure paresdmarc.ini, try this:

cp parsedmarc/parsedmarc.sample.ini parsedmarc/parsedmarc.ini

Then try again:

docker-compose up --build

And please use code tags to make your report easier to read. You should also insert the exact error message, i.e.
