+Useful Docker commands
+----------------------
+
+When typing **exit** in the container prompt, this will cause sometimes
+exiting the container and stopping it. When stopping a running Docker container
+all the changes will be lost when it is started again. There is a shortcut to
+quit the container without stopping it. Type CTRL+P+Q to keep the changes.
+To reconnect to the running container **DO NOT** use the *run* command again
+(since it will create a new container) use *exec* instead::
+
+ docker ps
+ <copy the container ID>
+ docker exec -ti <CONTAINER_ID> bash
+
+or simply::
+
+ docker exec -ti $(docker ps|grep functest|awk '{print $1}') bash
+
+There are other useful Docker commands that might be needed to manage possible
+issues with the containers.
+
+ * List the running containers::
+
+ docker ps
+
+ * List all the containers including the stopped ones::
+
+ docker ps -a
+
+ * It is useful sometimes to remove a container if there are some problems::
+
+ docker rm <CONTAINER_ID>
+
+ * Use the *-f* option if the container is still running, it will force to destroy it::
+
+ docker -f rm <CONTAINER_ID>
+
+The Docker image is named **opnfv/functest** and it is stored in the public
+Docker registry under the OPNFV account: dockerhub_.
+The are many different tags that have been created automatically by the CI
+mechanisms, but the one that this document refers to is **brahmaputra.1.0**.
+Other tags might cause some problems while running the tests.
+
+Check the Docker documentation dockerdocs_ for more information.
+
+
+Preparing the Functest environment
+----------------------------------
+
+Once the docker container is up and running, execute the following command in the
+prompt::
+
+ ${repos_dir}/functest/docker/prepare_env.sh
+
+NOTE: **${repos_dir}** is a default environment variable inside the docker
+container, which points to */home/opnfv/repos/*
+
+This script will make sure that the requirements to run the tests are met and will
+install the needed libraries and tools by all Functest test cases. It must be run
+only once every time the docker is started.
+
+
+Focus on the OpenStack credentials
+----------------------------------
+
+The OpenStack credentials are needed to run the tests against the VIM.
+There are 3 ways to provide them to Functest:
+
+ * using the -v option when running the Docker container
+ * create an empty file in /home/opnfv/functest/conf/openstack.creds and paste
+ the credentials in it.
+ * automatically retrieved using the following script::
+ $repos_dir/releng/utils/fetch_os_creds.sh
+
+Once the credentials are there, they shall be sourced before running the tests::
+
+ source /home/opnfv/functest/conf/openstack.creds
+
+or simply using the environment variable **$creds**::
+
+ . $creds
+
+After this, try to run any OpenStack command to see if you get any output,
+for instance::
+
+ openstack user list
+
+This will return a list of the actual users in the OpenStack deployment. In any
+other case, check that the credentials are sourced::
+
+ env|grep OS_
+
+This command must show a set of environment variables starting with *OS_*, for example::
+
+ OS_REGION_NAME=RegionOne
+ OS_DEFAULT_DOMAIN=default
+ OS_PROJECT_NAME=admin
+ OS_PASSWORD=admin
+ OS_AUTH_STRATEGY=keystone
+ OS_AUTH_URL=http://172.30.10.3:5000/v2.0
+ OS_USERNAME=admin
+ OS_TENANT_NAME=admin
+ OS_ENDPOINT_TYPE=internalURL
+ OS_NO_CACHE=true
+
+If still the OpenStack command does not show anything or complains about
+connectivity issues, it could be due to an incorrect url given to the OS_AUTH_URL
+environment variable. Check the deployment settings.
+
+Additional Options
+------------------
+In case you need to provide different configuration parameters to Functest (e.g.
+ commit IDs or branches for the repositories, ...) copy the config_functest.yaml
+ from the repository to your current directory and run docker with a volume::
-Firstly run the script to install functest environment::
+ wget https://git.opnfv.org/cgit/functest/plain/testcases/config_functest.yaml
- $ ${repos_dir}/functest/docker/prepare_env.sh
+ <modify the file accordingly>
-NOTE: ${repos_dir} is a default environment variable inside the docker
-container, which points to /home/opnfv/repos
+ docker run -ti -e \
+ "INSTALLER_TYPE=fuel" -e "INSTALLER_IP=10.20.0.2" \
+ opnfv/functest:brahmaputra.1.0 \
+ -v $(pwd)/config_functest.yaml:/home/opnfv/functest/conf/config_functest.yaml \
+ /bin/bash\
-Run the script to start the tests::
+However, this is not recommended since most of the test cases rely on static
+parameters read from this file, and changing them might cause problems.

Introduction
============
-** DOCUMENT IS IN PROGRESS FOR BRAHMAPUTRA **
-
This document describes how to install and configure Functest in OPNFV.
-Prerequisites
-=============
-
-The OPNFV deployment is out of the scope of this document but it can be found in
-XXX. The OPNFV platform is considered as the System Under Test (SUT) in this
-document.
-
-Several prerequisites are needed for functest:
-
- #. A Jumphost to run Functest on
- #. Docker daemon shall be installed on the Jumphost
- #. A public/external network created on the SUT
- #. Connectivity from the Jumphost to the SUT public/external network
- #. Connectivity from the Jumphost to the SUT management network
-
-NOTE: “Jumphost” refers to any server which meets the previous requirements.
-Normally it is the same server from where the OPNFV deployment has been
-triggered.
-
-Docker installation
--------------------
-
-.. _Ubuntu: https://docs.docker.com/installation/ubuntulinux/
-.. _RHEL: https://docs.docker.com/installation/rhel/
-
-Log on your jumphost then install docker (e.g. for Ubuntu)::
-
- curl -sSL https://get.docker.com/ | sh
-
-Add your user to docker group to be able to run commands without sudo::
-
- sudo usermod -aG docker <your_user>
-
-
-References:
-
- * Ubuntu_
- * RHEL_
-
-Connectivity to OPNFV management network
-----------------------------------------
-
-Some of the Functest tools need to have access to the OpenStack management
-network of the controllers `[1]`_.
-
-For this reason, an interface shall be configured in the Jumphost in the
-OpenStack management network range.
-
-Example::
-
- The OPNFV Fuel installation uses VLAN tagged 300 and subnet 192.168.1.0/24 as
- Openstack Management network.
- .
- Supposing that eth1 is the physical interface with access to that subnet:
- $ ip link add name eth1.300 link eth1 type vlan id 300
- $ ip link set eth1.300 up
- $ ip addr add 192.168.1.66/24 dev eth1.300
-
-
-External network on SUT
------------------------
-
-Some of the tests against the VIM (Virtual Infrastructure Manager) need an
-existing public network to succeed. This is needed, for example, to create
-floating IPs to access instances from the public network (i.e. Jumphost).
-
-By default, any of the four OPNFV installers provide a fresh installation with
-an external network created along with a router.
