Description
Design¶
- uncloud needs to know about opennebula VMs
- we have an importer for this one
- uncloud needs to be able to extract mappings for
- mac <-> nic
- ip address <-> nic
- VM <-> host (?)
- uncloud needs to be able to configure nft on all hosts
- ssh keys need to be configured

- consul can have watches: https://www.consul.io/docs/agent/watches.html

Checking mac addresses, inside != outside:
[17:49:56] server2.place6:~# ip l | grep -i -e 02:00:f0:a9:c4:09 -e 24181
251: one-24181-0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9200 qdisc htb master br-vm-place6 state UNKNOWN mode DEFAULT group default qlen 1000
[17:50:11] server2.place6:~# ip l sh dev one-24181-0
251: one-24181-0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9200 qdisc htb master br-vm-place6 state UNKNOWN mode DEFAULT group default qlen 1000

[17:50:21] server2.place6:~#
=> need mac address in database

Watching on different servers nicely works:
[17:54:10] server2.place6:~# consul kv put vm-firewall/a-vm-id/allow-one-23654-1 "2a09:2947::43/64" Success! Data written to: vm-firewall/a-vm-id/allow-one-23654-1 [17:53:17] server3.place6:~# consul watch -type=keyprefix -prefix=vm-firewall/ "/bin/echo updating firewall" updating firewall updating firewall
