Apache Kvrocks Overview

Secure your stack with a hardened Apache Kvrocks image freshly-built by Minimus. Minimus images always include the most up-to-date package version for all packages and dependencies contained in the image.

Apache Kvrocks is a distributed key-value NoSQL database that uses RocksDB as its storage engine and is compatible with the Redis protocol. Use it as a cost-efficient, persistent alternative to in-memory stores for large datasets that exceed available RAM.

Try It Out

Take the Minimus Apache Kvrocks image for a test run:

docker run --rm \
  -p 6666:6666 \
reg.mini.dev/apache-kvrocks

This command will start the Kvrocks server container and map port 6666/TCP in the Kvrocks container to port 6666/TCP on the localhost.

We can test the connection to the Kvrocks server either from another Kvrocks container (as a client) or from our host machine.

Option 1: From another Kvrocks container

In another terminal, run the following command to start and enter a client container:

docker run --rm --network host -it --entrypoint /bin/bash reg.mini.dev/apache-kvrocks

Once you're inside the container (you'll see a prompt like bash-5.2$), run the following command to retrieve server details from the Kvrocks instance using the Redis-compatible CLI:

redis-cli -h 127.0.0.1 -p 6666 info server

You should get a response something like:

# Server
kvrocks_version:2.16.0
redis_version:7.0.0
kvrocks_mode:standalone
tcp_port:6666
...

Option 2: From your host machine

In another terminal, install the Redis command-line tools using:

sudo apt install redis-tools

Once the tools are installed, you can run redis-cli commands to interact with your Kvrocks server container. For example, to view server details, run:

redis-cli -h 127.0.0.1 -p 6666 info server

You should receive output similar to:

# Server
kvrocks_version:2.16.0
redis_version:7.0.0
kvrocks_mode:standalone
tcp_port:6666
...

Technical Considerations

The Apache Kvrocks image provided by Minimus is a slim, security-hardened alternative to the public image from Docker Hub. The images are largely interchangeable, with a few differences as noted below.

Apache Kvrocks built by Minimus:

Runs as non-root by default, matching the public image's non-root default of user 999.
Listens on port 6666/TCP by default but does not expose the port. The public image listens on and exposes the same port by default.
The image does not expose a volume by default. The public image exposes the volume /var/lib/kvrocks.
Drill down on the version specification tab to see the default user, listening ports, entrypoint, volumes, environment variables, etc.

The Payoff

A hardened, minimal image that will remain more secure for the long run and accrue vulnerabilities at a slower rate.

See the risk reduction dashboard for a detailed CVE comparison over the past 30 days.
Review the compliance report to see the default hardening and security configurations for the image.
