A Jumphost to run Functest on + #. A Docker daemon shall be installed on the Jumphost + #. A public/external network created on the SUT + #. An admin/management network created on the SUT + #. Connectivity from the Jumphost to the SUT public/external network + #. Connectivity from the Jumphost to the SUT admin/management network + +WARNING: Connectivity from Jumphost is essential and it is of paramount +importance to make sure it is working before even considering to install +and run Functest. Make also sure you understand how your networking is +designed to work. + +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. + +NOTE: If your Jumphost is operating behind a company http proxy and/or +firewall, please consult first the section `Proxy Support`_, towards +the end of this document. The section details some tips/tricks which +*may* be of help in a proxified environment. + +Docker installation +------------------- +Docker installation and configuration is only needed to be done once +through the life cycle of Jumphost. + +If your Jumphost is based on Ubuntu, SUSE, RHEL or CentOS linux, please +consult the references below for more detailed instructions. The +commands below are offered as a short reference. + +*Tip:* For running docker containers behind the proxy, you need first +some extra configuration which is described in section +`Docker Installation on CentOS behind http proxy`_. You should follow +that section before installing the docker engine. + +Docker installation needs to be done as root user. You may use other +userid's to create and run the actual containers later if so desired. +Log on to your Jumphost as root user and install the Docker Engine +(e.g. for CentOS family):: + + curl -sSL https://get.docker.com/ | sh + systemctl start docker + + *Tip:* If you are working through proxy, please set the https_proxy + environment variable first before executing the curl command. + +Add your user to docker group to be able to run commands without sudo:: + + sudo usermod -aG docker <your_user> + +A reconnection is needed. There are 2 ways for this: + #.

This is needed, for example, to create floating IPs to access +VM instances through the public/external network (i.e. from the Docker +container). + +By default, the four OPNFV installers provide a fresh installation with +a public/external network created along with a router. Make sure that +the public/external subnet is reachable from the Jumphost. + +*Hint:* For the given OPNFV Installer in use, the IP sub-net address +used for the public/external network is usually a planning item and +should thus be known. Consult the OPNFV Configuration guide `[4]`_, and +ensure you can reach each node in the SUT, from the Jumphost using the +'ping' command using the respective IP address on the public/external +network for each node in the SUT. The details of how to determine the +needed IP addresses for each node in the SUT may vary according to the +used installer and are therefore ommitted here. + +Connectivity to Admin/Management network on SUT +----------------------------------------------- +Some of the Functest tools need to have access to the OpenStack +admin/management network of the controllers `[1]`_. + +For this reason, check the connectivity from the Jumphost to all the +controllers in cluster in the OpenStack admin/management network range. + +.. _`[1]`: https://ask.openstack.org/en/question/68144/keystone-unable-to-use-the-public-endpoint/ +.. _`[4]`: http://artifacts.opnfv.org/functest/danube/docs/configguide/index.html |
