Neo4j Aura Provisioning Skill

When to Use

• Creating an Aura instance (CLI, REST API, Python, Terraform)
• Pausing, resuming, resizing, or deleting an instance
• Downloading initial credentials from creation response
• Polling instance status: creating → running
• Setting up CI/CD provisioning or teardown pipelines
• Choosing instance tier (Free vs Professional vs Business Critical vs VDC)

When NOT to Use

• Cypher queries against running DB → neo4j-cypher-skill
• GDS algorithms on Aura → neo4j-gds-skill (Pro with plugin) or neo4j-aura-graph-analytics-skill (serverless)
• neo4j-admin / cypher-shell → neo4j-cli-tools-skill
• Application driver setup → use a language driver skill (python, javascript, java, go, dotnet)

Instance Tier Decision Table

AuraDB Free limits: 200k nodes, 400k rels; auto-pauses after 72 h inactivity; deleted if paused >30 days; no resize.

Auth Setup

CLI (aura-cli v1.7+)

Install (binary, not pip):

# macOS
curl -L https://github.com/neo4j/aura-cli/releases/latest/download/aura-cli-darwin-amd64.tar.gz | tar xz
sudo mv aura-cli /usr/local/bin/
aura-cli -v          # verify

Add credentials (from console.neo4j.io → Account Settings → API Credentials):

aura-cli credential add \
  --name "my-creds" \
  --client-id "$AURA_CLIENT_ID" \
  --client-secret "$AURA_CLIENT_SECRET"
aura-cli credential use --name "my-creds"

Verify:

aura-cli instance list --output table

REST API — Get Bearer Token

Token endpoint: POST https://api.neo4j.io/oauth/token Token expires: 3600 s (1 h). On 403 → refresh token.

TOKEN=$(curl -s --request POST 'https://api.neo4j.io/oauth/token' \
  --user "${AURA_CLIENT_ID}:${AURA_CLIENT_SECRET}" \
  --header 'Content-Type: application/x-www-form-urlencoded' \
  --data-urlencode 'grant_type=client_credentials' \
  | jq -r '.access_token')
echo "Token: ${TOKEN:0:20}..."

Use in all subsequent calls: --header "Authorization: Bearer $TOKEN"

Step 1 — List Tenants (Projects)

CLI:

aura-cli tenants list --output table
# Copy TENANT_ID for create operations

REST:

curl -s https://api.neo4j.io/v1/tenants \
  -H "Authorization: Bearer $TOKEN" | jq '.data[] | {id, name}'

Step 2 — Create Instance

CRITICAL: Capture output immediately. Initial password shown ONCE — never retrievable again. If lost: delete and recreate. Store aura-creds.json before doing anything else.

CLI

aura-cli instance create \
  --name "my-instance" \
  --cloud-provider gcp \
  --region europe-west1 \
  --type professional-db \
  --tenant-id "$TENANT_ID" \
  --output json | tee aura-creds.json

# Extract for .env
INSTANCE_ID=$(jq -r '.id' aura-creds.json)
PASSWORD=$(jq -r '.password' aura-creds.json)

REST API (full create)

RESPONSE=$(curl -s -X POST https://api.neo4j.io/v1/instances \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "name":           "my-instance",
    "cloud_provider": "gcp",
    "region":         "europe-west1",
    "type":           "professional-db",
    "tenant_id":      "'"$TENANT_ID"'",
    "memory":         "4GB",
    "version":        "5"
  }')
echo "$RESPONSE" | tee aura-creds.json
INSTANCE_ID=$(echo "$RESPONSE" | jq -r '.data.id')
PASSWORD=$(echo "$RESPONSE"   | jq -r '.data.password')

Instance create request body fields:

Step 3 — Poll Until RUNNING (CRITICAL — All Ops Are Async)

ALL lifecycle operations (create, pause, resume, resize) are async. Do NOT attempt connection or next operation until status = running (or paused for pause op).

poll_status() {
  local INSTANCE_ID=$1 TARGET=$2 MAX_WAIT=${3:-600}
  local ELAPSED=0 STATUS
  echo "Polling for status=$TARGET (max ${MAX_WAIT}s)..."
  while [ $ELAPSED -lt $MAX_WAIT ]; do
    STATUS=$(aura-cli instance get --instance-id "$INSTANCE_ID" --output json \
             | jq -r '.status' 2>/dev/null)
    echo "  [${ELAPSED}s] status=$STATUS"
    [ "$STATUS" = "$TARGET" ] && echo "Ready." && return 0
    [ "$STATUS" = "destroying" ] && echo "ERROR: instance is being destroyed" && return 1
    sleep 10; ELAPSED=$((ELAPSED + 10))
  done
  echo "TIMEOUT after ${MAX_WAIT}s — last status: $STATUS" && return 1
}

poll_status "$INSTANCE_ID" "running" 600

REST equivalent:

while true; do
  STATUS=$(curl -s "https://api.neo4j.io/v1/instances/$INSTANCE_ID" \
    -H "Authorization: Bearer $TOKEN" | jq -r '.data.status')
  [ "$STATUS" = "running" ] && break
  sleep 10
done

Status lifecycle:

creating → running → pausing → paused → resuming → running
                  ↘ destroying → (gone)

Step 4 — Write .env and Verify

CONNECTION_URI="neo4j+s://${INSTANCE_ID}.databases.neo4j.io"

cat > .env <<EOF
NEO4J_URI=${CONNECTION_URI}
NEO4J_USERNAME=neo4j
NEO4J_PASSWORD=${PASSWORD}
NEO4J_DATABASE=neo4j
AURA_INSTANCE_ID=${INSTANCE_ID}
EOF

# Ensure .env never committed
grep -q '^\.env$' .gitignore 2>/dev/null || echo '.env' >> .gitignore

# Verify connectivity
cypher-shell -a "$CONNECTION_URI" -u neo4j -p "$PASSWORD" "RETURN 'connected' AS status"

Step 5 — Lifecycle Operations

All operations require instance in the correct state. Wrong-state ops return 4xx error.

Pause

Required state: running

aura-cli instance pause --instance-id "$INSTANCE_ID"
poll_status "$INSTANCE_ID" "paused" 600

Resume

Required state: paused

aura-cli instance resume --instance-id "$INSTANCE_ID"
poll_status "$INSTANCE_ID" "running" 900   # resume can take longer

Resize (Professional+ only — NOT Free)

Required state: running; instance remains available during resize.

# REST only — CLI resize not available in v1.7
curl -s -X PATCH "https://api.neo4j.io/v1/instances/$INSTANCE_ID" \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"memory": "8GB"}'
poll_status "$INSTANCE_ID" "running" 600
# Cannot reduce below current usage level

Delete

IRREVERSIBLE. Export snapshots first if data needed.

aura-cli instance delete --instance-id "$INSTANCE_ID"
# No poll needed — immediate

REST:

curl -s -X DELETE "https://api.neo4j.io/v1/instances/$INSTANCE_ID" \
  -H "Authorization: Bearer $TOKEN"

Region Codes

AWS

GCP

Azure

Enterprise tiers (Business Critical, VDC) add 20+ additional regions per provider. Check console for full list. Free tier: GCP only; limited subset of regions.

Terraform Provider

terraform {
  required_providers {
    aura = {
      source  = "neo4j/neo4j-aura"
    }
  }
}

provider "aura" {
  client_id     = var.aura_client_id       # or AURA_CLIENT_ID env var
  client_secret = var.aura_client_secret   # or AURA_CLIENT_SECRET env var
}

resource "aura_instance" "db" {
  name           = "prod-db"
  type           = "professional-db"
  cloud_provider = "gcp"
  region         = "europe-west1"
  memory         = "4GB"
  tenant_id      = var.aura_tenant_id
}

output "neo4j_uri" {
  value     = "neo4j+s://${aura_instance.db.id}.databases.neo4j.io"
  sensitive = false
}
output "neo4j_password" {
  value     = aura_instance.db.password
  sensitive = true
}

After terraform apply: poll status before marking infra ready — Terraform resource creation returns when API call completes, not when DB is running.

Common Errors

API Rate Limits

Poll interval: ≥10 s to stay within limits on Free; 5 s safe on Pro+. On Retry-After header in 5xx response: wait that many seconds before retry.

Security Rules

• Write initial credentials to .env; verify .env in .gitignore before proceeding
• Never print PASSWORD in CI logs — write to secrets vault (AWS Secrets Manager, GitHub secret, Vault)
• Use from_env() / os.environ — never hardcode credentials
• If .env absent: python-dotenv load_dotenv() auto-loads; do NOT prompt user unless loading fails

Checklist

• .env created with URI/user/password; .env in .gitignore
• Initial credentials saved to secure storage immediately after create
• poll_status called after create — do NOT connect before status = running
• poll_status called after pause/resume
• Correct tier selected (Free for dev, Pro+ for production, BC for HA)
• Region confirmed available for chosen tier and cloud provider
• Tenant ID provided for all create/list operations (required in multi-tenant orgs)
• Token refreshed if > 1 h old (or 403 received)
• Delete confirmed by user — data loss is permanent, no recovery
