Pause all processes within one or more containers
$ docker pause CONTAINER [CONTAINER...]
docker pause command suspends all processes in the specified containers.
On Linux, this uses the freezer cgroup. Traditionally, when suspending a process
SIGSTOP signal is used, which is observable by the process being suspended.
With the freezer cgroup the process is unaware, and unable to capture,
that it is being suspended, and subsequently resumed. On Windows, only Hyper-V
containers can be paused.
See the freezer cgroup documentation for further details.
For example uses of this command, refer to the examples section below.
$ docker pause my_container
