Build Docker Image

Docker Image name: ariitk

docker build -t ariitk .

Make a Shared Directory between Host & Docker Container

Shared Directory Path: ~/Docker/Shared-Volumes/ariitk-Container

mkdir -p ~/Docker/Shared-Volumes/ariitk-Container

Note: You can use any of your directory for this

Running the Docker Container

Container Name: ariitk

sudo docker run -d -it --rm -v ~/Docker/Shared-Volumes/ariitk-Container:/home/Shared-Volume/ -v /tmp/.X11-unix/:/tmp/.X11-unix --net host --env="$(env | grep DISPLAY)" --name ariitk ariitk

Provide Permission to DISPLAY for Docker

xhost +local:docker

If you've problem in running the GUI Applications in the Container try the following methods:

Make sure that output of env | grep DISPLAY should contain 1 line and should look like this: DISPLAY=:1. If not then, manually feed the DISPLAY value in the run command. For example sudo docker run -d -it --rm -v ~/Docker/Shared-Volumes/ariitk-Container:/home/Shared-Volume/ -v /tmp/.X11-unix/:/tmp/.X11-unix --net host --env="DISPLAY=:1" --name ariitk <image_name/image_id>
If error = libGL error: MESA-LOADER: failed to retrieve device information. Add this parameter this in docker run : -e LIBGL_ALWAYS_SOFTWARE=1 and install the required libraries.

Note: We've provided --rm argument, so do all the work in the shared directory. Because all the data outside shared directory would be deleted as soon as the container is stopped. And in order to save any changes in the docker container, use docker commit to create a new version for the changes

Attach to Docker Container

Shell used: bash

docker exec -it ariitk /bin/bash

Initial Setup Inside the Container

Copy .bashrc of root user to ariitk user
Copy /root/.ardupilot_env to /user/ariitk/.ardupilot_env
Append export PATH=$PATH:/root/.local/bin/ to root user's .bashrc
MAVROS Setup

mkdir -p ardupilot_ws/src
cd ardupilot_ws/
catkin init 
cd src/
mkdir launch
roscp mavros apm.launch apm.launch

After this, edit apm.launch such that it uses a Network Port instead of Physical Port

<arg name="fcu_url" default="tcp://127.0.0.1:2626" />

Full File should look something like this

<launch>
	<!-- vim: set ft=xml noet : -->
	<!-- example launch script for ArduPilot based FCU's -->

	<arg name="fcu_url" default="tcp://127.0.0.1:2626" />
	<arg name="gcs_url" default="" />
	<arg name="tgt_system" default="1" />
	<arg name="tgt_component" default="1" />
	<arg name="log_output" default="screen" />
	<arg name="fcu_protocol" default="v2.0" />
	<arg name="respawn_mavros" default="false" />

	<include file="$(find mavros)/launch/node.launch">
		<arg name="pluginlists_yaml" value="$(find mavros)/launch/apm_pluginlists.yaml" />
		<arg name="config_yaml" value="$(find mavros)/launch/apm_config.yaml" />

		<arg name="fcu_url" value="$(arg fcu_url)" />
		<arg name="gcs_url" value="$(arg gcs_url)" />
		<arg name="tgt_system" value="$(arg tgt_system)" />
		<arg name="tgt_component" value="$(arg tgt_component)" />
		<arg name="log_output" value="$(arg log_output)" />
		<arg name="fcu_protocol" value="$(arg fcu_protocol)" />
		<arg name="respawn_mavros" value="$(arg respawn_mavros)" />
	</include>
</launch>

Setup ArduPilot Gazebo

cd ~
git clone https://github.com/khancyr/ardupilot_gazebo.git 
cd ardupilot_gazebo/
mkdir build 
cd build/
cmake ..
make -j4
sudo make install

Note: You've to run ArduPilot as root User At the end, the .bashrc file of ariitk user should Look something like this:

source /opt/ros/noetic/setup.bash
source /usr/share/gazebo/setup.sh
export GAZEBO_MODEL_PATH=~/ardupilot_gazebo/models
export GAZEBO_RESOURCE_PATH=~/ardupilot_gazebo/worlds:${GAZEBO_RESOURCE_PATH}
export PATH=/usr/lib/ccache:$PATH
source /home/ariitk/ardupilot/Tools/completion/completion.bash
source ~/.ardupilot_env
source /usr/share/gazebo/setup.sh

And .ardupilot.env like

export PATH=/opt/gcc-arm-none-eabi-10-2020-q4-major/bin:$PATH
export PATH=/home/ariitk/ardupilot/Tools/autotest:$PATH
export PATH=/usr/lib/ccache:$PATH

Test the Docker Container

To test the Successful Setup of Docker Container, run the following commands in different Terminals (in order)

roscore
gazebo --verbose ~/ardupilot_gazebo/worlds/iris_arducopter_runway.world
sim_vehicle.py -v ArduCopter -f gazebo-iris --console --map --out=tcpin:127.0.0.1:2626 # It should be run as root and the Network Address in --out should be the same that was edited in apm.launch
roslaunch apm.launch

You should see a Drone in the Middle of a Runway. To Test MAVROS and MAVPROXY. You can ARM the drone. List the ROS Topics and Services with the following commands.

rostopic list
rosservice list

ARM the Drone with the Following Service Call

rosservice call /mavros/cmd/arming true

Save the Initial Changes

To save the Initial Changes make an image of the container

docker commit ariitk ariitk/ardupilot

Export Docker Image

To export a docker Image, type the following command

docker save -o <filename>.tar ariitk/ardupilot

Using Docker Image

Import Docker Image

To import a docker image, type the following command

docker load -i <filename>.tar

You can then tag the import image with the following command

docker tag <image_id> my_custom_image:latest

You can find the image_id with the following command

docker image list

Make a Shared Directory between Host & Docker Container

Shared Directory Path: ~/Docker/Shared-Volumes/ariitk-Container

mkdir -p ~/Docker/Shared-Volumes/ariitk-Container

Run Docker Image

Container Name: ariitk

sudo docker run -d -it --rm -v ~/Docker/Shared-Volumes/ariitk-Container:/home/Shared-Volume/ -v /tmp/.X11-unix/:/tmp/.X11-unix --net host --env="$(env | grep DISPLAY)" --name ariitk <image_name/image_id>

Provide Permission to DISPLAY for Docker

xhost +local:docker

If you've problem in running the GUI Applications in the Container try the following methods:

Make sure that output of env | grep DISPLAY should contain 1 line and should look like this: DISPLAY=:1. If not then, manually feed the DISPLAY value in the run command. For example sudo docker run -d -it --rm -v ~/Docker/Shared-Volumes/ariitk-Container:/home/Shared-Volume/ -v /tmp/.X11-unix/:/tmp/.X11-unix --net host --env="DISPLAY=:1" --name ariitk <image_name/image_id>
If error = libGL error: MESA-LOADER: failed to retrieve device information. Add this parameter this in docker run : -e LIBGL_ALWAYS_SOFTWARE=1 and install the required libraries.

Attach to Docker Container

Shell used: bash

docker exec -it ariitk /bin/bash
