In the old days of software development, getting an application from code to production was slow and painful. Developers struggled with dependency hell as test and production environments differ in subtle ways, leading to code mysteriously working on one environment but not the other. Then along came Docker in 2013, originally created within dotCloud as an experiment with container technology to simplify deployment. Docker was open-sourced that March, and over the next 15 months it emerged as a leading container platform. In this newsletter, we’ll explore the history of container technology, the specific innovations that powered Docker's meteoric rise, and the Linux fundamentals enabling its magic.
