Migrate getty node to admin vlan
Impacts after migration:
- [1] still reachable as before
- the machine shall be reached at getty.internal.admin.swh.network (ssh).
Note: Node exposing getty service: rp1.internal.admin.swh.network [2].
Step-by-step plan:
-
Inventory:
- Reserve new ip in vlan 442 (192.168.50.80) [3]
- Deprecate the ip from vlan 440 (192.168.100.102) [4]
-
Puppet manifest adaptations for moving the node to the admin vlan
-
Firewall: Open rule to allow access from pergamon to getty:9000
-
On {pergamon, getty.admin}
- Stop puppet agent
-
On pergamon
- Deploy new puppet manifest change
-
On riverside:
-
Update the ip to the new vlan442 ip
- Connect through ssh and adapt /etc/network/interfaces with new ip
-
Modify directly through the proxmox ui (not
terraform
-ed yet) - Adapt hardware entry about network (proxmox ui) to change from vmbr0 to vmbr442
- Update the hostname to getty.i.a.s.n
-
Remove the puppet certificates
rm -rf /var/lib/puppet/ssl
(agent node) -
Update facts deployment and subnets
/etc/facter/facts.d/deployment.txt
toadmin
[5] - Reboot machine (poweroff, start)
-
Run puppet with
puppet agent --test --fqdn getty.internal.admin.swh.network
-
Install necessary facts for cloud-init to stop tampering with /etc/hosts
-
Update the ip to the new vlan442 ip
-
On pergamon:
- Run puppet agent
- Decommission getty.i.s.o certificate
-
On rp1:
- Run puppet agent
-
Inventory:
- Change the reserved ip status to active
- Update sentry node with its new ip
-
Terraform:
-
Reference sentry node in sysadm terraform admin manifestnode is diverging too much, the risk/benefit seems off so we don't do it.
