Run with volume for files generated during docker build
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I am using Docker to run unit tests, to generate Cobertura code coverage results, and then to generate an HTML reports on this (using ReportGenerator). I then publish BOTH the code coverage results file and the HTML reports to VSTS DevOps.
Here are the commands I need to run:
# Generates coverage.cobertura.xml for use in the next step.
dotnet test /p:CollectCoverage=true /p:CoverletOutputFormat=cobertura /p:CoverletOutput=codecoveragereports/
# Generates HTML reports from coverage.cobertura.xml file.
dotnet reportgenerator -reports:app/test/MyApplication.UnitTests/codecoveragereports/coverage.cobertura.xml -targetdir:codecoveragereports -reportTypes:htmlInline
And now in dockerfile:
WORKDIR ./app/test/MyApplication.UnitTests/
RUN dotnet test /p:CollectCoverage=true /p:CoverletOutputFormat=cobertura /p:CoverletOutput=codecoveragereports/
ENTRYPOINT ["/bin/bash", "-c", "dotnet reportgenerator -reports:codecoveragereports/*.xml -targetdir:codecoveragereports -reportTypes:htmlInline"]
And to build the image:
docker build -t myapplication.tests -f dockerfile --target tester .
And to run it:
docker run --rm -it -v $PWD/codecoveragereports:/app/test/MyApplication.UnitTests/codecoveragereports myapplication.tests:latest
The problem:
The results file generated on dotnet test does get generated (I can test this with RUN dir), but seems to disappear when I specify a volume (using -v) on docker run.
Is it not possible to create a volume on files which are generated in the image during docker build?

The life of your container can be very roughly represented like
docker build
- dot test --> codecoveragereports/
docker run -v
- docker mount volume
$PWD/codecoveragereportstocodecoveragereports, this obscured the previouscodecoveragereports
- your entrypoint script
So you need to output dot test to a temp folder, then copy it to your mount point at runtime (in the entrypoint).
dockerfile
COPY init.sh /
dot test --> /temp/
ENTRYPOINT ['/bin/bash', '/init.sh']
init.sh
cp /temp /app/test/MyApplication.UnitTests/codecoveragereports
exec ["/bin/bash", "-c", "dotnet reportgenerator -reports:codecoveragereports/*.xml -targetdir:codecoveragereports -reportTypes:htmlInline"]
