How to launch node from install directory
What I wanted
I want to reduce my docker image size through removing a cloned source code from my workspace in 'src' directory according to this suggestion. For that matter, I have just deployed my source code using the following commands:
# install package
sudo catkin config --install
catkin_make
catkin_make install
The problem
As a result, three folder have been generated inside 'catking_ws' workspace it self. Namely, build, devel and install. install directory generate with many other library folders. I then navigated in to /share/ folder and tried to roslaunch one of my launch file. This is the error that I got:
ERROR: cannot launch node of type [oxford_gps_eth/gps_node]: oxford_gps_eth
ROS path [0]=/opt/ros/melodic/share/ros
ROS path [1]=/home/ubuntu/catkin_ws/src
ROS path [2]=/opt/ros/melodic/share
No processes to monitor shutting down processing monitor...
Expectation
I was able to launch my node, even being in /install/share/ directory without removing the cloned source code in 'src' directory. I wanted to launch my nodes after building and remove my source code so that I can utilize my image.
