I’m studying Free Software Technician and a have a subject that call Free Software and Communities. I have to do a job with the objective of one open community. I choose Docker community because I use Docker for work and I love all the things you can do in a minimal time. But this is different, I use Docker and I use information from the community, but what is the purpose? Help each other to learn and use Docker? only that? Could you help me to find a better answer?
