# DESCRIPTION

|
|
|
The `docker pause` command suspends all processes in a container. On Linux,
|
|
|
|
|
this uses the cgroups freezer. 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. On Windows, only Hyper-V
|
|
|
|
|
containers can be paused.
