Adds several options for restricting subdomain creation:

  • Per domain Allowed Record types
  • Per domain Allowed Nodes

Updates restrictions on CloudflareDomains to be a compound unique on name and prefix, so multiple instances of the same domain with different prefixes can be created.

Closes #136

Summary by CodeRabbit

  • New Features

    • Administrators can restrict domains to specific DNS record types and nodes.
    • Subdomain creation now shows only domains and record types available for the selected server.
    • Domain settings display allowed record types and nodes, with improved editing controls.
    • Subdomain configuration validates domain and record-type permissions before applying changes.
    • Domains can now share names when distinguished by different prefixes.
  • Documentation

    • Added guidance on domain restrictions and troubleshooting unavailable DNS record types.
  • Localization

    • Added English and German labels for allowed record types and nodes.

31-31: Do not rewrite domain names during rollback.

When multiple prefixes share one name, this update changes every non-minimum row to <name>_<id>. The row no longer identifies the original Cloudflare zone. The generated name can also collide with an existing name, so the later unique('name') creation can fail after data is modified. Abort the rollback when duplicate names exist. Do not mutate cloudflare_domains.name.

📝 Walkthrough

Walkthrough

This change adds restrictions for allowed DNS record types and nodes. It stores the restrictions, exposes them in administration forms, filters server-facing subdomain choices, and validates permissions before Cloudflare synchronization.

Changes

Domain restrictions

Layer / File(s) Summary
Persistence and availability rules
subdomains/database/migrations/*, subdomains/src/Models/CloudflareDomain.php, subdomains/src/Enums/RecordType.php
The database stores allowed record types, compound domain names, and domain-node links. CloudflareDomain calculates available domains and record types for a server.
Domain restriction administration
subdomains/src/Filament/Admin/Resources/CloudflareDomains/CloudflareDomainResource.php, subdomains/lang/*/strings.php
The admin resource edits and displays allowed record types and nodes. Domain name and prefix use composite uniqueness and cannot change during edits.
Subdomain selection and enforcement
subdomains/src/Filament/Admin/Resources/Servers/RelationManagers/SubdomainRelationManager.php, subdomains/src/Filament/Server/Resources/Subdomains/SubdomainResource.php, subdomains/src/Models/Subdomain.php, subdomains/README.md
Subdomain forms use server-specific domains and domain-specific record types. Synchronization rejects unauthorized domains and record types. Documentation describes the restrictions.

Priority: ➖ Normal — Schedule this domain restriction change because it adds administrator controls, persistence, availability filtering, and enforcement for subdomain use.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Severity of issue fixed: Medium

as nullable, backfill existing cloudflare_domains rows with ["A", "AAAA",
"CNAME", "SRV"], then enforce the column as NOT NULL, preserving compatibility
with PostgreSQL and SQLite.

In

- Around line 20-23: Update the migration’s down() method to check for duplicate
name values before altering indexes and abort the rollback if any exist;
otherwise drop the compound name/prefix unique constraint and recreate the
original name-only unique constraint defined by the table migration.
- Line 13: Update the cloudflare domain persistence flow around
CloudflareDomain::create() so an absent prefix is normalized to a non-null value
before insertion, ensuring the existing unique(['name', 'prefix']) constraint
rejects duplicates. Preserve the intended distinction between valid prefixes and
absent prefixes while preventing concurrent NULL-prefix rows from bypassing
uniqueness.

In `@subdomains/src/Models/Subdomain.php`:
- Line 47: Update the Cloudflare lookup query to pass the scalar value from the
record_type RecordType enum via its value property, ensuring the request sends a
string such as type=A rather than the enum instance.

126-128: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Require an SRV service type before returning RecordType::SRV.

This method adds RecordType::SRV when the server has an allocation and a node target. Subdomain::upsertOnCloudflare() also requires SRVServiceType::fromServer($server). A server without that type can select SRV and then receives a synchronization error.

Add the same service-type check here before adding RecordType::SRV.

A null or empty allowed_record_types/allowed_nodes should be treated as "all record types"/"all nodes".
