Building a Docker Image from a Dockerfile

A Dockerfile is a text file containing a series of instructions to create a Docker image. Here's how to build an image using a Dockerfile.

1. Create a Dockerfile: Write a Dockerfile with the necessary instructions for your application. Example:

   # Use the MRS UAV System the base image
   FROM ctumrs/mrs_uav_system:latest
   
   # Install additional packages into the image
   RUN sudo apt-get -y install <my_dependency>
   
   # Specify the default command to run
   CMD ["/ros_entrypoint.sh"]
2. Save the Dockerfile: Save the Dockerfile in the root directory of your project.
3. Build the Docker Image: Use the docker build command to build the image. Run this command in the same directory as your Dockerfile:

docker build -t <image-name>:<tag> .

Example:

docker build -t my-app:latest .

• The -t flag assigns a name and tag to your image (e.g., my-app:latest).
• The . at the end specifies the build context (the current directory).

Dockerfile for the MRS UAV System

FROM ctumrs/ros:noetic

RUN apt-get -y update

# workaround interractive prompts during apt installations
RUN echo 'debconf debconf/frontend select Noninteractive' | sudo debconf-set-selections
RUN DEBIAN_FRONTEND=noninteractive apt-get -y install keyboard-configuration

# INSTALL the MRS UAV System

RUN apt-get -y install software-properties-common curl bash

RUN curl https://ctu-mrs.github.io/ppa-stable/add_ppa.sh | bash

RUN apt-get -y install ros-noetic-mrs-uav-system-full

CMD ["/ros_entrypoint.sh"]
