Full Description

Cisco Meraki CMX API demo app - as a Docker Container

This application show you how to get started using the Cisco Meraki CMX API.
CMX (Connected Mobile Experiences) is Cisco’s location analytics and engagement platform, and it’s integrated into Cisco Meraki wireless products.
To learn more about what you can do with CMX, see the Cisco Meraki CMX site and at Cisco Meraki Developers

Forked and merged Readme.

Table of contents


  1. This code is for sample purposes only. Before running in production,
    you should probably add SSL/TLS support by running this server behind a
    TLS-capable reverse proxy like nginx.

  2. You should also test that your server is capable of handling the rate
    of events that will be generated by your networks. A good rule of thumb is
    that your server should be able to process all your network's nodes once per
    minute. So if you have 100 nodes, your server should respond to each request
    within 600 ms. For more than 100 nodes, you will probably need a multithreaded
    web app.

Network infrastructure requirements

  • The app requires using one or more Cisco Meraki MR wireless access points (APs).
  • A valid license is required for each Meraki AP.
  • Note: this app does not work with other Cisco APs or non-Cisco APs.

Setting up the Cisco Meraki Dashboard

Let’s say you plan to run this app on a docker host you control called

  1. Go to the Cisco Meraki dashboard and configure the CMX API (find it under Network-wide > Configure > General) with the url
  2. Choose a secret and enter it into the dashboard.
  3. Make note of the validation code that dashboard provides.
  4. Pass the secret (red box) and validation code (green box) to your docker container when you start it - Starting docker container

Docker host

Interactive with output to tty

  • Start your app by running this interactive container to show output

    docker run --rm -it -p 4567:4567 \
    -e CMX_SECRET=secret \
    -e CMX_VALIDATOR=validator \
  • If you want to use another port then 4567

    docker run --rm -it -p 80:80 \
    -e CMX_SECRET=secret \
    -e CMX_VALIDATOR=validator \
    -e CMX_PORT=80 \
  • If you want to bind your server to a certain ip-address of the host

    docker run --rm -it -p 4567:4567 \
    -e CMX_BIND= \
    -e CMX_SECRET=secret \
    -e CMX_VALIDATOR=validator \
    --net=host robertcsapo/cisco-meraki-cmx-api-app

Running it as daemon

docker run -d -p 4567:4567 \
-e CMX_SECRET=secret \
-e CMX_VALIDATOR=validator \
  • Accessing the container when running as daemon
    docker exec -it <containerid/containername> /bin/bash

Build container from scratch

OpenShift ( support

Red Hat® OpenShift is a container application platform that brings docker and Kubernetes to the enterprise. in openshift folder.

It's now possible to host this application through in ciscoshipped folder.

Validate the docker service in Meraki Dashboard

  • Click the “Validate server” button in CMX Location Push API configuration in
    the dashboard. Meraki cloud servers will perform a GET to your server, and you will
    see a log message like this:
    [26/Mar/2014 11:52:09] "GET /events HTTP/1.1" 200 6 0.0024

  • If you do not see such a log message, check your firewall and make sure
    you’re allowing connections to port 4567. You can confirm that the server
    is receiving connections on the port using
    telnet 4567

  • Once the Meraki cloud has confirmed that the URL you provided returns the expected
    validation code, it will begin posting events to your URL. For example, when
    a client probes one of your access points, you’ll see a log message like

    [2014-03-26T11:51:57.920806 #25266]  INFO -- : AP 11:22:33:44:55:66 on ["5th Floor"]: {"ipv4"=>"", "location"=>{"lat"=>37.77050089978862, "lng"=>-122.38686903158863,"unc"=>11.39537928078731}, "seenTime"=>"2014-05-15T15:48:14Z", "ssid"=>"Cisco WiFi","os"=>"Linux", "clientMac"=>"aa:bb:cc:dd:ee:ff","seenEpoch"=>1400168894, "rssi"=>16, "ipv6"=>nil, "manufacturer"=>"Meraki"}
  • After your first client pushes start arriving (this may take a minute or two),
    you can get a JSON blob describing the last client probe (where {mac} is the client mac address):{mac}

  • You can also view the sample frontend at:
    Try connecting your mobile device to your network, and entering your mobile device‘s WiFi MAC in the frontend.

Sample output code

The JSON blob sent by Meraki servers to your app is formatted as follows:

  "apFloors":["500 TF 4th"],
    "ssid":"SSID 1",

A specific client device’s details can be retrieved, for example:

may return

  "seenAt":"Fri Apr 18 00:01:41.479 UTC 2014",
