Two things are for certain – space is hard, and Docker is not just for web content! Space software development traditionally lags behind state of the art software process for good reason – our missions are long (7+ years), we run on highly constrained embedded hardware, and the software cannot fail. Docker, along with a devops mentality, has helped us create a scalable, parallelizable and rapidly deployable test infrastructure for DART, NASA’s mission to hit an asteroid at 6 km/s.
During the presentation, we will walk through how our dev cycle has changed from a human based testing system to an automated one. We will outline how we are using Docker (and NASA Goddard’s Core Flight Executive) for both our embedded development environment and our scalable test environment. Next, we will discuss what deployment means to us (and how different it is from web deployment). Lastly, we will explore lessons learned on how our hardware-centric testing approach was adapted into a software-based approach: what worked, what didn’t, what we wish we could do someday.
How can you help? We are new to Docker. We are excited to share our experiences and hear from the Docker community on our use cases, technological hurdles that we faced, our solutions to these problems, and how we can harness Docker to the fullest extent.
