Cache

Add Cache > Valkey. Valkey is the open-source continuation of Redis: anything that speaks Redis (ioredis, redis-py, BullMQ, Sidekiq, Laravel queues) works with it. Versions 7.2, 8 (default) and 9.

What your app gets

Variable	Example
REDIS_URL	redis://app:…@cache-7:6379

Apps that read VALKEY_URL, REDIS_URI, CACHE_URL or REDIS_CONNECTION_STRING get that name too. Fields: uri, host, port, user, password.

Accounts: Root, Application (the default for links), Read-write and Read-only. The anonymous default user is off.

Data is temporary

Valkey keeps its data in memory. A restart, redeploy or sleep can empty it. Use it for caches, sessions and job queues that can be rebuilt, and keep anything you can’t lose in a database.

Connecting from your laptop

External access works as for Postgres: add allowed IPs, pick accounts, deploy. Use TLS (rediss://). The certificate is self-signed, so pass the downloaded certificate or --insecure:

redis-cli -u "rediss://readonly:PASSWORD@cache-7.example.dev:25003" --insecure ping
