+Compass installer local development env usage Tips
+--------------------------------------------------
+In the compass-functest local test case check and development environment, in order
+to get openstack service inside the functest container, some parameters should be
+configured during container creation, which are hard to guess for freshman. This
+section will provide the guideline, the parameters values are defaults here, which should
+be adjusted according to the settings, the complete steps are given here so as
+not to appear too abruptly.
+
+1, Pull Functest docker image from public dockerhub::
+
+ docker pull opnfv/functest:<Tag>
+
+<Tag> here can be "brahmaputra.1.0", "colorado.1.0", etc. Tag omitted means the
+latest docker image::
+
+ docker pull opnfv/functest
+
+2, Functest Docker container creation
+
+To make a file used for the environment, such as 'functest-docker-env'::
+
+ OS_AUTH_URL=http://172.16.1.222:35357/v2.0
+ OS_USERNAME=admin
+ OS_PASSWORD=console
+ OS_TENANT_NAME=admin
+ OS_VOLUME_API_VERSION=2
+ OS_PROJECT_NAME=admin
+ INSTALLER_TYPE=compass
+ INSTALLER_IP=192.168.200.2
+ EXTERNAL_NETWORK=ext-net
+
+Note: please adjust the content according to the environment, such as 'TENANT_ID'
+maybe used for some special cases.
+
+Then to create the Functest docker::
+
+ docker run --privileged=true --rm -t \
+ --env-file functest-docker-env \
+ --name <Functest_Container_Name> \
+ opnfv/functest:<Tag> /bin/bash
+
+Note: it is recommended to be run on jumpserver.
+
+3, To attach Functest container
+
+Before trying to attach the Functest container, the status can be checked by::
+
+ docker ps -a
+
+to attach the 'Up' status Functest container and start bash mode::
+
+ docker exec -it <Functest_Container_Name> bash
+
+4, Functest environemnt preparation and check
+
+To see the Section below `Preparing the Functest environment`_.

Inside the Functest docker container, the following directory structure
