Answer
Pause holds namespaces to checkpoint containers without stopping processes.
Quick Answer
docker pause uses the Linux cgroups freezer subsystem to suspend all processes in a container — they stop executing but stay in memory. The container's filesystem, network, and state remain intact. docker unpause resumes all processes exactly where they left off. Useful for momentarily freezing containers without killing them.
