+# Docker Checkpoint & Restore
+
+Checkpoint & Restore is a new feature that allows you to freeze a running
+container by checkpointing it, which turns its state into a collection of files
+on disk. Later, the container can be restored from the point it was frozen.
+
+This is accomplished using a tool called [CRIU](http://criu.org), which is an
+external dependency of this feature. A good overview of the history of
+checkpoint and restore in Docker is available in this
+[Kubernetes blog post](http://blog.kubernetes.io/2015/07/how-did-quake-demo-from-dockercon-work.html).
+
+## Installing CRIU
+
+If you use a Debian system, you can add the CRIU PPA and install with apt-get
+[from the criu launchpad](https://launchpad.net/~criu/+archive/ubuntu/ppa).
+
+Alternatively, you can [build CRIU from source](http://criu.org/Installation).
+
+You need at least version 2.0 of CRIU to run checkpoint/restore in Docker.
+
+## Use cases for checkpoint & restore
+
+This feature is currently focused on single-host use cases for checkpoint and
+restore. Here are a few:
+
+- Restarting the host machine without stopping/starting containers
+- Speeding up the start time of slow start applications
+- "Rewinding" processes to an earlier point in time
+- "Forensic debugging" of running processes
+
+Another primary use case of checkpoint & restore outside of Docker is the live
+migration of a server from one machine to another. This is possible with the
+current implementation, but not currently a priority (and so the workflow is
+not optimized for the task).
+
+## Using Checkpoint & Restore
+
+A new top level commands `docker checkpoint` is introduced, with three subcommands:
+- `create` (creates a new checkpoint)
+- `ls` (lists existing checkpoints)
+- `rm` (deletes an existing checkpoint)
+
+Additionally, a `--checkpoint` flag is added to the container start command.
+
+The options for checkpoint create:
+
+    Usage:  docker checkpoint [OPTIONS] CONTAINER CHECKPOINT_ID
+
+    Checkpoint the specified container
+
+      --leave-running=false    leave the container running after checkpoint
+
+And to restore a container:
+
+    Usage:  docker start --checkpoint CHECKPOINT_ID [OTHER OPTIONS] CONTAINER
+
+
+A simple example of using checkpoint & restore on a container:
+
+    $ docker run --security-opt=seccomp:unconfined --name cr -d busybox /bin/sh -c 'i=0; while true; do echo $i; i=$(expr $i + 1); sleep 1; done'
+    > abc0123
+
+    $ docker checkpoint create cr checkpoint1
+
+    # <later>
+    $ docker start --checkpoint checkpoint1 cr
+    > abc0123
+
+This process just logs an incrementing counter to stdout. If you `docker logs`
+in between running/checkpoint/restoring you should see that the counter
+increases while the process is running, stops while it's checkpointed, and
+resumes from the point it left off once you restore.
+
+Note that seccomp is only supported by CRIU in very up to date kernels.
