Run with volume for files generated during docker build












0















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




          1. docker mount volume $PWD/codecoveragereports to codecoveragereports, this obscured the previous codecoveragereports

          2. 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"]
