## Creating a service or VM
### Service
- have kustomized manifests
- creates IPv6 only, probably certificate enabled service
- external (???) proxy
- internal: could have a mapped IPv4 address
- pvc for storage
- rbd vs cephfs decision in general + per use case
### External/other DNS
- needs to be pointed to the service IP
- kustomized manifests need to be updated/annotated ("also this
domain")
## Service List
### DNS servers
- bind / knot
- authoritatitve
- files in cephfs?
- IPv4 from outside (jool)?
### Matrix
### Django
- moving sample site(s)
- f.i. ula registry
### Etherpad
- cephfs based pvc
### wireguard
- via mapped IPv4 for outside
- via routing -- might be able to includ bird (?)
- network mapping in kustomize, later netbox api?
- peers in configmap (?)
### Nextcloud
- pvc -> cephfs, s3, rbd?
- need to test resize
### IPv4
- can we use a crd/operator for this?
- Jool inside cluster
- Routed /24 or similar
- Distribution based on label(s) to pods/services
- Maybe using an ingress (+IPv4)
## Clusters
- Distributed over places?
