Rebot seems not to run in dockerimage

[peterfranssen]

Describe the bug
I tried to follow the steps in of the earlier reported issues in about rerunning failed tests. The rerunning is working fine, but it seems not to merge the results and produces additional logging

To Reproduce
Currently I managed to get below code running, including running failed tests. I assume the issue is somewhere in grabbing the output files from the correct path and merging them. Both the output files are created in the reports directory.

docker run --rm \
  -v ${PWD}/reports:/opt/robotframework/reports:Z \
  -v ${PWD}/rfafricapwa/tests:/opt/robotframework/tests:Z \
  --mount type=bind,source=${PWD}/rfafricapwa/resources,target=/opt/robotframework/resources \
  --user $(id -u):$(id -g) \
  ppodgorsek/robot-framework:latest ||
      
docker run --rm \
  -v ${PWD}/reports:/opt/robotframework/reports:Z \
  -v ${PWD}/rfafricapwa/tests:/opt/robotframework/tests:Z \
  --mount type=bind,source=${PWD}/rfafricapwa/resources,target=/opt/robotframework/resources \
  -e ROBOT_OPTIONS="--rerunfailed /opt/robotframework/reports/output.xml -o output2.xml" \
  --user $(id -u):$(id -g) \
  ppodgorsek/robot-framework:latest ||
  
docker run --rm \
  -v ${PWD}/reports:/opt/robotframework/reports:Z \
  -e REBOT_OPTIONS="-d /opt/robotframework/reports -l logpaadesktop -x junitoutput --merge /opt/robotframework/reports/output*.xml" \
  --user $(id -u):$(id -g) \
  ppodgorsek/robot-framework:latest

The part which uploads the reports to Git Hub Actions:

# Publish testresults to Github Actions
        - name: Publish Unit Test Results
          uses: mikepenz/action-junit-report@v2
          if: always()
          with:
            report_paths: ${{ github.workspace }}/reports/*.xml
            update_check: true
            check_name:   "SK AF PWA - Daily Regression Test"
        # upload test reports as a zip file
        - name: Upload reports
          uses: actions/upload-artifact@v1
          if: always()
          with:
            name: reports
            # set path to Robot Framework results reports. Exclude dummy file that is needed because of ppodgorsek image priviledges.
            path: ${{ github.workspace }}/reports

To me it seems that there are no entrypoints in this dockerfile to run the rebot command at all. So although you can give REBOT_OPTIONS, the rebot command is never actually run.

See Issue 300 if you're willing to create your own fork (there seems to be some samples).

My solution was to run the rebot outside the docker image, although it requires me to install the robot in the server where I run the docker.
