+Docker container which works with ONOS Scenario Test Coordinator (STC)
+
+Before building docker image:
+1. Check out the master branch and go to: $ONOS_ROOT/tools/dev/docker.
+2. Copy $ONOS_ROOT/bazel-bin/onos.tar.gz here, assuming you have successfully built one.
+3. Copy your public key ~/.ssh/id_rsa.pub here.
+
+
+Build docker image as follows. You may tag your image as you like.
+```
+$ sudo docker build -t onos-sshd . -f Dockerfile-sshd
+```
+
+If you want to choose the version of Atomix, pleae build as follows:
+```
+$ ATOMIX_VERSION=3.1.4 sudo docker build --build-arg ATOMIX_VERSION -t onos-sshd . -f Dockerfile-sshd
+```
+
+Run 3 docker containers:
+```
+$ sudo docker run -t -d --name onos1 onos-sshd
+$ sudo docker run -t -d --name onos2 onos-sshd
+$ sudo docker run -t -d --name onos3 onos-sshd
+```
+
+Check ip of docker containers created:
+```
+$ sudo docker inspect --format '{{ .NetworkSettings.IPAddress }}' onos1
+```
+
+If not found, create cell definition file e.g. $ONOS_ROOT/tools/test/cells/3docker. Make sure ip's match your settings.
+```
+export ONOS_NIC="172.17.0.*"
+export OCI="172.17.0.2"
+export OC1="172.17.0.2"
+export OC2="172.17.0.3"
+export OC3="172.17.0.4"
+export ONOS_APPS="drivers,openflow,fwd"
+export ONOS_USER="sdn"
+```
+
+Set up cell definition:
+```
+$ cell 3docker
+```
+
+Execute STC setup: 
+```
+$ stc setup
+```
+
+Check status using ONOS CLI:
+```
+$ ssh -p 8101 karaf@$OC1    # password is karaf
+```
