# pause

The `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](https://www.kernel.org/doc/Documentation/cgroup-v1/freezer-subsystem.txt)
|
|
for further details.
