Deploy Apache Kvrocks

Deploy and Host Apache Kvrocks on Railway

Apache Kvrocks is a distributed key-value database that speaks the Redis protocol but stores data in RocksDB on disk. Existing Redis clients and commands work against it, while the dataset can grow far beyond the available memory. It is an Apache Software Foundation project used for caches, queues and counters.

About Hosting Apache Kvrocks

This template runs the official apache/kvrocks:2.17.0 image as one service. Data lives on a Railway volume, so keys survive restarts and redeploys, and memory use stays low even for large datasets. The server requires the generated password and listens on IPv4 and IPv6. Services in the project connect over the private network, and a TCP proxy allows connections from outside Railway. Kvrocks accepts AUTH but not the two-argument AUTH default form, so connection URLs leave the username empty. The process runs as the unprivileged kvrocks user and shuts down cleanly on redeploy.

Common Use Cases

• A Redis-compatible cache or store for data that does not fit in memory
• Persistent counters, sessions and rate-limit buckets that must survive restarts
• Replacing a large in-memory Redis to cut memory costs

Dependencies for Apache Kvrocks Hosting

• apache/kvrocks:2.17.0 (official image)
• A Railway volume at /var/lib/kvrocks for the RocksDB data

Deployment Dependencies

• Apache Kvrocks
• Kvrocks 2.17.0 release
• Railway TCP proxy

Implementation Details

Reference it from another service with ${{kvrocks.REDIS_URL}}. The start command passes settings as flags (--bind "0.0.0.0 ::", --workers 4, --requirepass) and reads an empty config from standard input, so no config file is needed on the volume.

This is a community-maintained deployment package and does not imply affiliation with or endorsement by the Apache Software Foundation or the Kvrocks project.

Why Deploy Apache Kvrocks on Railway?

Railway is a singular platform to deploy your infrastructure stack. Railway will host your infrastructure so you don't have to deal with configuration, while allowing you to vertically and horizontally scale it.

By deploying Apache Kvrocks on Railway, you are one step closer to supporting a complete full-stack application with minimal burden. Host your servers, databases, AI agents, and more on Railway.
