The use case: how LINE deploys CircleCI
LINE Corp moved from Jenkins to CircleCI to cut the effort of managing CI tooling and plug-ins for its large developer base. Developers run tests in Docker containers with their own language libraries, inherit GitHub Enterprise permissions, and can SSH into build environments to troubleshoot.
In the customer’s words

Developers use Docker containers to run tests and they can easily build an environment including language libraries using Docker images. There is no additional work for administrators to do on configurations, nor is any communication needed to ask administrators to install or upgrade plug-ins.
