High level architecture ----------------------- The high level architecture of Functest within OPNFV can be described as follows:: CIMC/Lights+out management Admin Private Public Storage PXE + + + IP_PRIV/24 | | | | + + | | | | IP_PUB/24 | | +----------------------------+ | | + | | | | | | | | +-----+ Jumphost | | | | | | | +----------+ | | | | | | | | | | | | +--------------------+ | | | | | | | | | | | | | | | | | Tools | +--------------------+ | | | | | - Rally | | | | | | | | | - Robot | | | | | | | | | - TestON | | | | | | | | | | | | | | | | | | Testcases | | | | | | | | | - VIM | | | | | | | | | -- vPing | | | | | | | | | -- vPing_userdata | | | | | | | | | -- Tempest | | | | | | | | | -- Rally | | | | | | | | | - Controller | | | | | | | | | -- odl | | | | | | | | | -- onos | | | | | | | | | -- opencontrail | | | | | | | | | | | | | | | | | | Features | | | | | | | | | - vIMS | | | | | | | | | | | | | | | | | +--------------------+ | | | | | | | +------------------------------+ | | | Functest Docker | | | | | | | +---------------------------------------+ | | | | | | | | +----------------------------+ | | | | | | | | | | +----------------+ | | | | | | 1 | | | | | +----+ +--------------+-+ | | | | | | | 2 | | | | | | | | +--------------+-+ | | | | | | | | 3 | | | | | | | | | +--------------+-+ | | | | | | | | | 4 | | | | | | +-+ | | +--------------+-+ | | | | | | | | | 5 +---------------+ | | | | +-+ | | nodes for | | | | | | | | | deploying +-------------------------+ | | | +-+ | opnfv | | | | | | | | SUT +-----------------------------------+ | | +-+ | | | | | | | +--------------------------------------------+ | +----------------+ | | | | | | | | | | + + + + All the libraries and dependencies needed by all the Functest tools are pre-installed in the Docker image. This allows running Functest on any platform on any Operating System. The automated mechanisms inside the Functest Docker container will: * retrieve OpenStack credentials * prepare the environment according to the SUT * perform the appropriate tests * push the results into the OPNFV test result database This Docker image can be integrated into CI or deployed independently. Please note that the Functest container has been designed for OPNFV, however, it would be possible to adapt it to any VIM+controller environment since most of the test cases are integrated from upstream communities. The test cases are described in the Functest User Guide `[2]`_ Prerequisites ============= The OPNFV deployment is out of the scope of this document but it can be found in `[4]`_. 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 previously. Docker installation ------------------- .. _Ubuntu: https://docs.docker.com/installation/ubuntulinux/ .. _RHEL: https://docs.docker.com/installation/rhel/ Log on your Jumphost and 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 References: * Ubuntu_ * RHEL_ 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. Docker container). By default, the four OPNFV installers provide a fresh installation with an external network created along with a router. Make sure that subnet is reachable from the Jumphost 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. For example, if the management network is on VLAN 300 and subnet 192.168.1.0/24 and assuming 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 This is just an example about how to configure an interface with vlan, but it might differ depending on the deployment settings on each installer. Check the corresponding installer instructions for more info. Installation and configuration ============================== .. include:: ./configguide.rst Integration in CI ================= In CI we use the Docker image and execute the appropriate commands within the container from Jenkins.
