Endpoint: REDIS_HOST=localhost:24089.
Memorystore (Redis/Valkey) agent testing
Memorystore (Redis/Valkey) local testing for AI agents
Use LocalCloud when an agent needs to create, exercise, and reset Memorystore (Redis/Valkey) resources without touching a real Google Cloud project. The same SDK shape points at localhost through REDIS_HOST=localhost:24089.
Endpoints: RESP :24089.
Evidence state: partial; Local development coverage is partial. Known limits: Pub/Sub, Lua, streams, and MULTI/EXEC are not supported..
Registry default: on; assembled default: on (verified); minimum tier: community.
Persistence: service-data (verified). Valkey data and instance metadata survive restart with the LocalCloud volume
Route the SDK before writing code
Start LocalCloud, export REDIS_HOST=localhost:24089, and make the agent perform one Memorystore (Redis/Valkey) operation before changing application logic. That catches accidental production routing early.
Prefer one representative behavior over broad smoke tests
A useful agent check creates local Memorystore (Redis/Valkey) state, reads it back with the project SDK, and records which feature was covered. It should not require a GCP account, service-account key, or billing project.
Use only documented setup paths
Create deterministic state through a contract-documented seed registrar or through an operation listed on this page. Do not assume every service supports seed data, reset, or persistent state.
Copy-ready setup
Commands and prompts
Use these snippets as starting points, then keep the checks scoped to localhost until you intentionally validate against real Google Cloud.
Environment
eval "$(localcloud env)"
# Verify that the generated environment includes REDIS_HOST; do not replace a CLI-remapped value with a hard-coded port. Compatibility
Local check versus release validation
| Area | LocalCloud local check | Real GCP still needed for |
|---|---|---|
| SDK routing | REDIS_HOST=localhost:24089 points clients at localhost. | Production endpoint, auth, IAM, quota, and regional behavior. |
| Supported features | RESP commands (partial) — Redis/Valkey-compatible data path is available. | Pub/Sub, Lua, streams, and MULTI/EXEC are not supported.; Cloud Redis admin API: unsupported |
| Agent safety | No default cloud account, credentials, or billing project required. | Final release validation in the target GCP project. |
Use the sandbox deliberately
- Permitted workflows use local endpoint values and should stop rather than fall back to real Google Cloud or real credentials. The Public Preview License permits individuals and organizations, including for-profit companies, to use LocalCloud for non-production internal development, testing, CI, evaluation, and pilots.
- LocalCloud emulates bounded local development workflows. Validate application behavior against real Google Cloud before production deployment.
- Before production deployment, unset LocalCloud emulator environment variables and validate behavior against real Google Cloud.
- Local development coverage is partial. Known limits: Pub/Sub, Lua, streams, and MULTI/EXEC are not supported..
Keep the agent on the supported path
- Memorystore (Redis/Valkey) service page — Service-specific supported and unsupported capability list.
- Compatibility matrix — Check current support boundaries before relying on a local-only test.
- Service catalog — Review every LocalCloud service, endpoint, and limitation.
- SDK examples — Use standard Google Cloud SDKs pointed at localhost.
- Seed data — Load deterministic fixtures for repeatable agent and CI runs.
