Redka, a Redis compatible server that persists to a durable, queryable SQLite database, ready on first boot.
Redka speaks the Redis wire protocol for the five core data types (strings, lists, hashes, sets, sorted sets) while storing everything in a SQLite database you can query directly with SQL. It suits embedded caches, lightweight test environments, and small scale workloads that want Redis style structures with a durable, inspectable relational backend. It implements a subset of Redis commands and runs as a single node (no clustering, replication, pub/sub, or scripting).
cloudimg ships Redka hardened and fully patched on Ubuntu 24.04 LTS, bound to loopback only by default with the SQLite store on a dedicated data disk, a connection note written on first boot, and a paired deploy guide. 24/7 support is included with every image.
