The management network is used extensively for all internal communication. Since the original use of the network was a private network before it was exposed for external communication in a distributed cloud configuration, it was never designed to be reconfigured. To support MGMT network reconfiguration the idea is to configure the applications to use the hostname/FQDN instead of a static MGMT IP address. In this way the MGMT network can be changed and the services and applications will still work since they are using the hostname/FQDN and the DNS will be responsible to translate to the current MGMT IP address. The use of FQDN will be applied for all installation modes: AIO-SX, AIO-DX, Standard, AIO-PLUS and DC subclouds. But given the complexities of supporting the multi-host reconfiguration, the MGMT network reconfiguration will focus on support for AIO-SX only. The DNSMASQ service must start as soon as possible to translate the FQDN to IP address, for this reason the dnsmasq will start as soon the management-ip is ready. Test plan ( Debian only ) - AIO-SX and AIO-DX virtualbox installation IPv4/IPv6 - Standard virtualbox installation IPv6 - DC virtualbox installation IPv4 ( AIO-SX/DX subclouds ) - AIO-SX and AIO-DX installation IPv4/IPv6 - AIO-DX plus installation IPv6 - DC IPv6 and subcloud AIO-SX - AIO-DX host-swact - DC IPv4 virtualbox with subcloud AIO-DX and AIO-DX - AIO-SX to AIO-DX migration - netstat -tupl ( no services are using the MGMT IP address ) - Ran sanity/regression tests Story: 2010722 Task: 48889 Depends-On: https://review.opendev.org/c/starlingx/config/+/886208 Change-Id: If118132410a5a3db4c3a9d0ba029f4d45521574d Signed-off-by: Fabiano Correa Mercer <fabiano.correamercer@windriver.com> |
