Problem statement
As a QE eng I want to create a instance in OpenStack after deployment with a IP that can be reached from controller-0, ie a IP on the public network.
Currently in scenarios/uni/uni04delta-ipv6/04-scenario-vars.yaml we have the network configuration that will be applied in the ansible-post-deployment.log to create the public network. That definition is IPv4:
cifmw_os_net_setup_config: - name: public external: true shared: false is_default: true provider_network_type: flat provider_physical_network: datacentre subnets: - name: public_subnet cidr: 192.168.122.0/24 allocation_pool_start: 192.168.122.171 allocation_pool_end: 192.168.122.250 gateway_ip: 192.168.122.1 enable_dhcp: true - name: private external: false shared: true subnets: - name: private_subnet cidr: '10.2.0.0/24' allocation_pool_start: 10.2.0.10 allocation_pool_end: 10.2.0.250 gateway_ip: 10.2.0.1 enable_dhcp: true
The problem is that on Controller-0 (or on any other host for that matter) we don't have any IPv4 routing. So there's no way to create a FIP in that public network.
ip -4 r -> empty
Solution: Create a IPv6 cifmw_os_net_setup_config definition
cifmw_os_net_setup_config: - name: public external: true shared: false is_default: true provider_network_type: flat provider_physical_network: datacentre availability_zone_hints: [] subnets: - name: public_subnet cidr: 2620:cf:cf:aaaa::/64 allocation_pool_start: 2620:cf:cf:aaaa::100 allocation_pool_end: 2620:cf:cf:aaaa::200 gateway_ip: 2620:cf:cf:aaaa::1 enable_dhcp: true ip_version: 6 ipv6_address_mode: slaac ipv6_ra_mode: slaac - name: private external: false shared: true subnets: - name: private_subnet cidr: fd10:2:0::/64 allocation_pool_start: fd10:2:0::10 allocation_pool_end: fd10:2:0::250 gateway_ip: fd10:2:0::1 enable_dhcp: true ip_version: 6 ipv6_address_mode: slaac ipv6_ra_mode: slaac
Would work and match the external definition in scenarios/uni/uni04delta-ipv6/01-net-def.yaml .
Setting priority as critical as it's blocking a CIX.
