Switch DNS Provider

[splattner]

Current Setup

• We are currently using Hosttech as our Domain Registrar and also as our DNS Service.
• 3 Domains, acend.ch, labz.ch, training.puzzle.ch (only a subdomain delegation)
• DNS Zone is manually managed trough hosttech's Web UI
• We use the Cert-Manager Hosttech Webhook Plugin on our acend k8s cluster and also on the k8s/rke2 based training cluster
• We also use Terraform to managed some records for our acend Kubernetes Cluster and also for the training cluster

Issues

• no NS records can be created so we cannot forward any subdomain to an other DNS provider (e.g. GCP, Azure etc)
• no official Terraform provider (we are currently using a generic restapi provider)
• Cert-Manager webhook not really maintained (last commit 2 years)
• only single user / account for administration
• Using the api (specially with cert-manager) sometimes feels slow and sometimes also don't really work reliable

Proposal / Possible Solutions

We wan't to migrate to an other DNS Provider

Possible solutions and some requirements are:

	hosttech (existing)	gandi.net	Hetzner (our Iaas Provider)	Cloudflare
DNS Service	x	x	x	x
Domain Registrar	x	x	-	- (ch Domain not supported)
Zone Delegation	Only full zone, no subzone delegation (NS Records)	Only subzones (NS Records) gandi has to be the dns registrar	Only subzones (NS Records) because its not a registrar	Only subzones (NS Records) because cannot be used as registrar for ch Domain
Domain Transfer required	no	yes	not possible	not possible with ch Domain
Cert-Manager	x	x	x	x
Terraform Provider	- (possible with generic restapi provider)	x	- (no official provider)	x
Multi Account	-	x	-	x
API	x	x	x	x
ALL Record Typs	-	x	x	x
Pricing	included in Domain CHF 4.90 / year	included in Domain $39.98 / year	Free	Free, might have some limitations to be verified (paid plans available
Other Services	-	none that seems to be interesting to us	we are already using Hetzner Cloud	A lot of other Services, CDN/Caching, WAF, Block Storage etc
