Artifact building and publishing</div><div class="">2. QA jobs:</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>2.1. Master node installation from ISO</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>2.2. Slave nodes provisioning</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>2.3. Software deployment</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>2.4. Workload verification</div><div class=""><br class=""></div><div class="">Current upstream nodepool limitations are pre-spwaned nodes, small flavors and, only l3 connectivity. Also, we have no PXE booting and VLAN trunking in OpenStack itself. So, the main problem with moving this pipeline to nodepool is to emulate IT tasks: installation from ISO and nodes provisioning.</div><div class=""><br class=""></div><div class="">Actually the point is: to test Fuel and test rest of OpenStack components against Fuel we mostly need to test stage artifact building, deployment and verification. So we need to make Fuel installable from packages and create overlay L2 networking. I've found no unsolvable problems right now to check most of scenarios with this approach.</div><div class=""><br class=""></div><div class="">Besides artifact building step, there are next actions items to do to run Fuel QA test:</div><div class=""><br class=""></div><div class="">1. Automate overlay networking setup. I've used <a href="https://www.tinc-vpn.org/" class="">https://www.tinc-vpn.org/</a> as a L2 switching overlay, but OpenVPN could be tool of choice. Action items:</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span> - overlay networking setup should be integrated in fuel-devops</div><div class=""><br class=""></div><div class="">2. Automate Fuel master node codebase installation from packages, including repo adding and deployment.
