DNS Setup for AI Edge

This guide prepares a domain for use with a Datum AI Edge by creating a DNS zone, an apex ALIAS record, and a subdomain CNAME — all pointing at the AI Edge endpoint.

This guide assumes your domain is already delegated to Datum nameservers. See DNS for nameserver details and ALIAS record behavior.

Prerequisites

datumctl installed and authenticated
A valid Project
Domain delegated to Datum nameservers

Configuration Steps

Step 1: Set Variables

The TARGET value is your AI Edge endpoint hostname. Find it in the Datum portal under your AI Edge’s generated hostname, or via:

datumctl get httpproxy <name> --namespace default -o yaml

Windows (PowerShell)

$PROJECT   = "your-project-id"
$NAMESPACE = "default"
$ZONE      = "your-zone-name"
$DOMAIN    = "your-domain.example.com"
$TARGET    = "your-endpoint.datumproxy.net."

macOS / Linux

PROJECT="your-project-id"
NAMESPACE="default"
ZONE="your-zone-name"
DOMAIN="your-domain.example.com"
TARGET="your-endpoint.datumproxy.net."

TARGET must include a trailing dot. Without it, the value will be treated as a relative name and DNS resolution will fail.

Step 2: Create the DNS Zone

Windows (PowerShell)

@"
apiVersion: dns.networking.miloapis.com/v1alpha1
kind: DNSZone
metadata:
  name: $ZONE
  namespace: $NAMESPACE
spec:
  dnsZoneClassName: datum-external-global-dns
  domainName: $DOMAIN
"@ | datumctl apply -f - --project $PROJECT --validate=false

macOS / Linux

cat <<EOF | datumctl apply -f - --project $PROJECT --validate=false
apiVersion: dns.networking.miloapis.com/v1alpha1
kind: DNSZone
metadata:
  name: $ZONE
  namespace: $NAMESPACE
spec:
  dnsZoneClassName: datum-external-global-dns
  domainName: $DOMAIN
EOF

--validate=false disables client-side schema validation. It is required here because datumctl does not bundle schemas for DNS API types locally.

Verify the zone is accepted and programmed:

datumctl get dnszones --project $PROJECT --namespace $NAMESPACE

Wait until both ACCEPTED and PROGRAMMED show True before proceeding.

Step 3: Create the Apex ALIAS Record

Points the root domain (@) at the AI Edge endpoint.

Windows (PowerShell)

@"
apiVersion: dns.networking.miloapis.com/v1alpha1
kind: DNSRecordSet
metadata:
  name: ${ZONE}-apex
  namespace: $NAMESPACE
spec:
  dnsZoneRef:
    name: $ZONE
  recordType: ALIAS
  records:
    - name: "@"
      ttl: 300
      alias:
        content: $TARGET
"@ | datumctl apply -f - --project $PROJECT --validate=false

macOS / Linux

cat <<EOF | datumctl apply -f - --project $PROJECT --validate=false
apiVersion: dns.networking.miloapis.com/v1alpha1
kind: DNSRecordSet
metadata:
  name: ${ZONE}-apex
  namespace: $NAMESPACE
spec:
  dnsZoneRef:
    name: $ZONE
  recordType: ALIAS
  records:
    - name: "@"
      ttl: 300
      alias:
        content: $TARGET
EOF

Step 4: Create a Subdomain CNAME

Points a subdomain (e.g., app.your-domain.example.com) at the same endpoint.

Windows (PowerShell)

@"
apiVersion: dns.networking.miloapis.com/v1alpha1
kind: DNSRecordSet
metadata:
  name: ${ZONE}-app-cname
  namespace: $NAMESPACE
spec:
  dnsZoneRef:
    name: $ZONE
  recordType: CNAME
  records:
    - name: "app"
      ttl: 300
      cname:
        content: $TARGET
"@ | datumctl apply -f - --project $PROJECT --validate=false

macOS / Linux

cat <<EOF | datumctl apply -f - --project $PROJECT --validate=false
apiVersion: dns.networking.miloapis.com/v1alpha1
kind: DNSRecordSet
metadata:
  name: ${ZONE}-app-cname
  namespace: $NAMESPACE
spec:
  dnsZoneRef:
    name: $ZONE
  recordType: CNAME
  records:
    - name: "app"
      ttl: 300
      cname:
        content: $TARGET
EOF

Verification

Check Record Status

datumctl get dnsrecordsets --project $PROJECT --namespace $NAMESPACE

Both records should show ACCEPTED=True and PROGRAMMED=True.

Check DNS Resolution

Windows (PowerShell)

Resolve-DnsName $DOMAIN
Resolve-DnsName "app.$DOMAIN"

macOS / Linux

dig $DOMAIN
dig app.$DOMAIN

Both names should resolve to the AI Edge endpoint.

Cleanup

Windows (PowerShell)

datumctl delete dnsrecordset ${ZONE}-app-cname `
  --project $PROJECT --namespace $NAMESPACE --ignore-not-found

datumctl delete dnsrecordset ${ZONE}-apex `
  --project $PROJECT --namespace $NAMESPACE --ignore-not-found

datumctl delete dnszone $ZONE `
  --project $PROJECT --namespace $NAMESPACE --ignore-not-found

macOS / Linux

datumctl delete dnsrecordset ${ZONE}-app-cname \
  --project $PROJECT --namespace $NAMESPACE --ignore-not-found

datumctl delete dnsrecordset ${ZONE}-apex \
  --project $PROJECT --namespace $NAMESPACE --ignore-not-found

datumctl delete dnszone $ZONE \
  --project $PROJECT --namespace $NAMESPACE --ignore-not-found

Troubleshooting

Symptom	Root Cause	Resolution
Zone stuck at `PROGRAMMED=False`	Domain not delegated to Datum nameservers	Update nameservers at your registrar
`nslookup` / `dig` returns NXDOMAIN	Zone not yet propagated	Wait 1–2 minutes and retry
ALIAS resolves to wrong address	`TARGET` missing trailing dot	Re-apply the record with a trailing dot on the target
Record not appearing	`--validate=false` omitted	Re-apply with `--validate=false`

Summary

DNS zones use kind: DNSZone at dns.networking.miloapis.com/v1alpha1
The DNS zone class is always datum-external-global-dns — it is platform-provided and not user-configurable
Use recordType: ALIAS for the apex (@) and recordType: CNAME for subdomains
The TARGET value must include a trailing dot
All DNS apply commands require --validate=false
Delete record sets before deleting the zone
