What is it

A docker file for ROS Noetic (ROS 1)

One time setup

docker build -f ./ubuntu_20_04_ros_dockerfile_1 .
# do "docker images" and find the hash of the image just created; "04f7aeebc6f7" below
docker tag 04f7aeebc6f7 ros1_harish
# tag it so it's easier to start, etc.

# @todo simplify

Everytime setup and cleanup

docker run -it ros1_harish /bin/bash

Do this when done:

On the command prompt
#exit
