## External Dependencies

Continuous integration builds use Docker versions 1.11.2, 1.12.6, 1.13.1,
and 17.03.2. These versions were validated on Kubernetes 1.8. However,
consult an appropriate installation or upgrade guide before deciding what
versions of Docker to use.

- Docker 1.13.1 and 17.03.2

    - Shared PID namespace, live-restore, and overlay2 were validated.
