Docker Captain Program

Docker Captain is a distinction that Docker awards select members of the community that are both experts in their field and are passionate about sharing their Docker knowledge with others. Captains are Docker ambassadors (not employees) and their commitment to sharing their expertise has a huge impact on the Docker community – whether they are blogging, writing books, speaking, running workshops, creating tutorials and classes, offering support in forums, or organizing and contributing to local events – they help make Docker’s mission of democratizing technology possible.

Docker Captains are eager to bring their technical expertise to new audiences both offline and online around the world – don’t hesitate to reach out to them via the social links below!

If you’re interested in becoming a Docker Captain, please send an email to [email protected]
