Alpine linux build of Nominum dnsperf

Building an image out of this repository won't create an image with the sample file, unless you explicitly create your own by uncommenting few lines in Dockerfile (see below). However I'm providing an image with the compressed sample data file (qdf tag)

docker run -it --rm quay.io/ssro/dnsperf

or

docker run -it --rm quay.io/ssro/dnsperf:qdf

1. Clone this repo and cd into it
2. docker build -t dnsperf .
3. docker run -it --rm some-dnsperf dnsperf

For help just invoke dnsperf -h inside the container

Uncomment below code inside dockerfile to include the file and rebuild

# RUN wget ftp://ftp.nominum.com/pub/nominum/dnsperf/data/queryfile-example-current.gz \
#  && gunzip queryfile-example-current.gz \
#  && rm -rf queryfile-example-current.gz

This will take some time, based on how fast is the download.

Also, the sample file can be downloaded inside the container using the above ftp link

Query server 127.0.0.1 (using the sample query file) for 60 seconds from 1 client with 10 requests/sec:

dnsperf -s 127.0.0.1 -d queryfile-example-current -l 60 -c 1 -Q 10

Test 2 DNS servers for 30 seconds:

dnsperf -s 127.0.0.1 -s 127.0.0.2 -d queryfile-example-current -l 30
