nats-box

A lightweight container with NATS and NATS Streaming utilities.

• nats - NATS management utility (README)
• nsc - create NATS accounts and users
• nats-top - top-like tool for monitoring NATS servers
• stan-pub - publish messages to NATS Streaming
• stan-sub - subscribe to messages from NATS Streaming
• stan-bench - benchmark stan

Getting started

Use tools to interact with NATS.

$ docker run --rm -it synadia/nats-box:latest
~ # nats pub -s demo.nats.io test 'Hello World'
16:33:27 Published 11 bytes to "test"

Running in Kubernetes:

# Interactive mode
kubectl run -i --rm --tty nats-box --image=synadia/nats-box --restart=Never
nats-box:~# nats sub -s nats hello &
nats-box:~# nats pub -s nats hello world

# Non-interactive mode
kubectl apply -f https://nats-io.github.io/k8s/tools/nats-box.yml
kubectl exec -it nats-box -- /bin/sh

Using NSC to manage NATS v2 users and accounts

You can mount a local volume to get nsc accounts, nkeys, and other config back on the host.

$ docker run --rm -it -v $(pwd)/nsc:/nsc synadia/nats-box:latest

# In case NSC not initialized already:
nats-box:~# nsc init -d /nsc
$ tree -L 2 nsc/
