Add Dockerfile for ROS

[Taka-Kazu]

Thank you for your work!

I added a Dockerfile for running ROS package of openvslam on Docker.

Dockerfile.ros is the modification of Dockerfile.desktop. I changed the version of OpenCV to 3 and added the installation procedure of ROS.

You can try it as follows (mainly same as "Running on Docker"):

$ cd /path/to/openvslam
$ docker build -t openvslam-ros -f Dockerfile.ros .
$ xhost +local:
$ docker run --rm -e DISPLAY=$DISPLAY -v /tmp/.X11-unix/:/tmp/.X11-unix:ro -v /your/vocab/path:/vocab -v /your/config/path:/config openvslam-ros rosrun openvslam run_slam -v /vocab/orb_vocab.dbow2 -c /config/config.yaml

Thank you for creating a Dockerfile for ROS!
I tried to build it with docker build -t openvslam-ros -f Dockerfile.ros . but I get this error:
unable to prepare context: unable to evaluate symlinks in Dockerfile path: lstat /home/dominik/dev_ws/openvslam/Dockerfile.ros: no such file or directory

Do I have to do anything else before I can build this? The original docker file works fine for me without errors.
Thanks in advance!

No special preparation should be required.

• Be sure to checkout this PR brunch
• The existence of Dockerfile.ros

should be reaffirmed.

I had a similar issue.
Please Check branch name. Default branch is master, you must change add-ros-dockerfile branch.

$ cd openvslam && git checkout add-ros-dockerfile
$ docker build -t openvslam-ros -f Dockerfile.ros .
