Aiming for the stx-openstack application hardening, this change implements the plugin logic to gather the number of available compute nodes and, for anything that is not an AIO-SX deployment, configure the neutron dhcp_agents_per_network count accordingly [1]. When only two computes are available this config is set to 2, whenever three or more compute nodes are available this config is set to 3. There are scenarios in which the compute node fails and if it is hosting the DHCP agent for a given openstack network, VMs on that VM won't be able to receive DHCPOFFER and fail to receive ip and ping. Partial-Bug: 2030883 [1] https://docs.openstack.org/neutron/latest/admin/config-dhcp-ha.html#enabling-dhcp-high-availability-by-default TEST PLAN: PASS - Build plugins (k8sapp_openstack) PASS - Build stx-openstack helm charts PASS - Apply stx-openstack and verify the Neutron config * Check dhcp_agents_per_network count: /etc/neutron/neutron.conf - AIO-SX = 1 - AIO-DX = 2 PASS - Execute stx-openstack sanity tests locally Change-Id: I6f32ac8a1706467be0be67920a3a750bb7c6b01e Signed-off-by: Thales Elero Cervi <thaleselero.cervi@windriver.com> |

k8sapp-openstack
This project contains StarlingX Kubernetes application specific python plugins for the openstack application. These plugins are required to integrate the openstack application into the StarlingX application framework and to support the various StarlingX deployments.
