From the root pxf folder run:
docker build -t gpdb6_pxf_regress:latest -f arenadata/Dockerfile .This will build an image called gpdb6_pxf_regress with the tag latest. This image is based on gpdb6_regress:latest, which additionally contains pxf sources and pxf artifacts tarball in /tmp/build/pxf_src and /tmp/build/pxf_tarball folders respectively.
During the image building phase compile_pxf.bash script additionally calls test make target, which calls make -C cli/go/src/pxf-cli test and make -C server test commands.
To additionally test fdw and external-table parts you may call:
docker run --rm -it \
--privileged --sysctl kernel.sem="500 1024000 200 4096" \
gpdb6_pxf_regress:latest /tmp/build/pxf_src/arenadata/test_in_docker.sh
