Why another nsq image?

I personally use this image to build nsq producers located in the same container as the nsqd instance (http://nsq.io/deployment/topology_patterns.html#distributed-systems).
S6 is used as the supervisor (http://skarnet.org/software/s6/index.html) based on the @just-containers S6 overlay Alpine image (https://hub.docker.com/r/justcontainers/base-alpine/).
More info there: https://github.com/just-containers/s6-overlay

How to use it?

The same way you use the official nsq image

docker run cyppan/nsq /<command>

<command> being one of

• nsqd
• nsqlookupd
• nsqadmin
• nsq_to_nsq
• nsq_to_http
• nsq_to_file
• nsq_tail
• nsq_stat
• nsq_pubsub

Producer app + nsqd mode

S6 allows you to manage this properly
Dockerfile example:

FROM cyppan/nsq
RUN echo "#!/usr/bin/execlineb -P \n /nsqd" > /etc/services.d/nsqd/run
ADD producer.py /
CMD python producer.py
