Google Cloud Memorystore

GCP-managed Redis/Valkey — Instance details Primary Endpoint, AUTH string, TLS on 6378, VPC-only.

Memorystore for Redis (and the Valkey offering) is private-IP only inside your VPC. drivers.store.kv stays redis.

The one rule

Open the instance → Connections for Primary Endpoint + port; Security for the AUTH string. There is no public hostname to paste.

Find credentials (current console)

  1. Google Cloud Console → Memorystore → Redis (or Valkey) → click Instance ID.
  2. Connections section → copy Primary Endpoint (private IP) and Port (usually 6379).
  3. If AUTH is enabled: Security section → AUTH string (or gcloud redis instances get-auth-string INSTANCE --region=REGION).
  4. If in-transit encryption is on: download the TLS server certificate from the instance page; clients use port 6378 with that CA (not plain 6379).
process env
# AUTH on, transit encryption off (common default)
REDIS_URL=redis://:AUTH_STRING@10.0.0.3:6379

# Transit encryption on → port 6378 + rediss:// + CA configured in the client
# REDIS_URL=rediss://:AUTH_STRING@10.0.0.3:6378

Cloud Run / Cloud Functions need a Serverless VPC Access connector on the same network.

Production guidance

TopicGuidance
NetworkingPrivate IP only — never a public endpoint option
AUTHOptional but recommended; string is on the instance Security panel
TLSNot default — enable in-transit encryption explicitly; port becomes 6378
TiersBasic vs Standard (replica) — pick before you need HA

Real gotcha — TLS port flip

Enabling in-transit encryption changes the client port to 6378 and requires the server CA. Leaving REDIS_URL on :6379 after enabling TLS looks like a mysterious timeout — update port and scheme together.
