-# Docker testing
-
-The `Dockerfile.cmake_dpkg_flags` can be used to simulate the build that the
-ros_buildfarm will perform using calling the CMake building system with the
-dpkg-buildflags typically used in the ROS build environment. To test it:
-
-```
-docker build -f Dockefile.cmake_dpkg_flags -t ros_drake_vendor_cmake .
-docker run -i -t ros_drake_vendor_cmake /bin/bash
-```
