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.
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
- Backup and Restore for AIO-SX/AIO-DX
