Installing the FFMPEG library can help users record videos with Headless browsers. That's the reason it's reasonable for us to install it into the Docker Image as well.
Currently, Katalon Docker Image doesn’t include the FFmpeg library. You can build your own image by following these steps:
Create a docker image file with this content:
FROM katalonstudio/katalon RUN apt-get -y update RUN apt-get install -y ffmpeg
Build your own image. E.g.:
docker build -t mybuild .
Run your docker with the Katalon script. E.g.:
docker run -t --rm -v "$(pwd)":/tmp/project mybuild katalonc.sh -projectPath=/tmp/project - browserType="Chrome" -retry=0 -statusDelay=15 -testSuitePath="Test Suites/TS_RegressionTest"
