It is a standalone executable package that includes everything needed to run the application. Docker container run isolated from the host system and other containers. + +A `Docker image` is a **snapshot of an application or system** that has been packaged with all the necessary dependencies and configurations required to run and work for a desired use case. It can be thought of a template or a blueprint for creating a `Docker container`. + +In `Introduction to Robotics` we will provide you a `Docker image` that is a snapshot of an **Ubunutu operating system** with the **Robot Operating System (ROS)** installed and all the necessary additional libraries that will be necessary for this course. + +In the following section you will find information on how to install `Docker` and how to start a running `Docker container` as an instance of the `Docker image` we provided for this course. ### Installing Docker + Comprehensive instructions on how to **install** `Docker Desktop` on your machines operating system can be found [here](https://docs.docker.com/get-docker/).
