Docker 1.12 has a nice set of improvements that significantly improve the ability to administrate the Docker daemon. https://t.co/bXt4PwPXRr— Kelsey Hightower (@kelseyhightower) 31. Juli 2016
On the Docker GitHub release/changelog page of
v1.12.0 under the Runtime section the first point:
Add –live-restore daemon flag to keep containers running when daemon shuts down, and regain control on startup
This new option allows containers to keep running even when stopping, restarting or upgrading the Docker daemon.
--live-restore flag keeps containers running during a Docker daemon update.
