Usage: docker pause CONTAINER [CONTAINER...] Pause all processes within one or more containers Options: --help Print usage
docker pause command uses the cgroups freezer to suspend all processes in
a container. Traditionally, when suspending a process the
SIGSTOP signal is
used, which is observable by the process being suspended. With the cgroups freezer
the process is unaware, and unable to capture, that it is being suspended,
and subsequently resumed.
See the cgroups freezer documentation for further details.
