Introduction

Dockerfile to create a Docker container image for Warp 10.

Getting started

Installation

The easiest way to setup the Warp10 platform is to use Docker. Builds of Warp10's Docker image are available on Dockerhub. It is the recommended method of installation. A 'Continuous Integration' version has been provided. This version is available on Dockerhub with the 'ci' suffix. This version embeds a pair of READ/WRITE tokens named respectively 'READ', 'WRITE'.

Running your Warp10 image

Start your image binding the external ports 8080 and 8081 in all interfaces to your container.

Docker containers are easy to delete. If you delete your container instance, you'll lose the Warp10 store and configuration. So by default you should add a volume mapping to the containers /data folder.

  docker run --volume=/var/warp10:/data -p 8080:8080 -p 8081:8081 -d -i warp10io/warp10:1.0.15-1-ga07cb94

In this example you bind the container internal data folder, /data to your local folder /var/warp10.

You must use the same --volume option in all your other docker commands on warp10 image.

Generating Tokens

The Warp 10 platform is built with a robust security model that allows you to have a tight control of who has the right to write and/or read data. The model is structured around the concepts of data producer, data owner and application, and WRITE and READ tokens.

The 'ci' version embeds a pair of pre-generated READ/WRITE tokens named respectively 'READ', 'WRITE'. Otherwise, for the purposes of this setup, you need to generate write and read tokens for a test application for a test user that is both the producer and the owner of the data. In order to interact with the user/token/application system, you need an interactive access to Warp10's Worf component. You get it by executing worf.sh on the running container.

First, get the container id for your running Warp 10 image:

  $ docker ps
  CONTAINER ID        IMAGE                 COMMAND                  CREATED             STATUS              PORTS                              NAMES
  821b868e20be        warp10io/warp10:1.0.15-1-ga07cb94   "/bin/sh -c ${WARP10_"   3 minutes ago       Up 3 minutes        0.0.0.0:8080-8081->8080-8081/tcp   cranky_noyce

Then run docker exec to run Worf console on that container id:

  docker exec   -t -i 821b868e20be worf.sh

Inside Worf console, you can use the encodeToken command to generate both a READ and a WRITE token for the default users and application.

Testing the container

To test the running container, push a single GTS containing one data in the platform using your WRITE token.

  curl -v -H 'X-Warp10-Token: WRITE_TOKEN' --data-binary "1// test{} 42" 'http://127.0.0.1:8080/api/v0/update'

If everything is OK, you should receive a HTTP 200

When using Docker on Mac OS or Windows, there is no binding between Warp 10 API address and the host (docker is runned throw a Virtual Machine). To reach Warp10 you need to replace 127.0.0.1 by the real Ip address of the container. To get it, use a simple docker-machine ip default>, the container address is also shown in the Settings/Ports page of your container. If you used the shared volume between the container and the host, you can access to the virtual machine using docker-machine ssh default> and inspect the repertory /var/warp10. Don't hesitate to check on docker-machine documentation.

Get this data using your READ tokens.

curl -v  --data-binary "'READ_TOKEN' 'test' {} NOW -1 FETCH" 'http://127.0.0.1:8080/api/v0/exec'

If everything is OK, you should receive a HTTP 200 OK with your datapoint in JSON format.

A full getting started is available to guide your first steps into Warp 10.

Using Quantum

Warp 10's Quantum is a web application aiming to allow users to interact with the platform in an user-friendly way, offering an alternative to command-line interaction.

A standalone version of Quantum is packaged in the Docker image you have just installed, listening on the port 8081. In a Linux system (with binding between Warp 10 API address and the host) you can access Quantum at 127.0.0.1:8081. In Mac OS or Windows, there is no binding between Warp 10 API address and the host, you need to replace 127.0.0.1 by the real Ip address of the container as explained in the precedent section.

Build the image

If you want to build your own Warp10 image, clone this repository

  git clone https://github.com/cityzendata/warp10-docker.git

Execute docker build inside your local copy

  cd warp10-docker
  docker build -t myrepo/warp10:1.0.15-1-ga07cb94 .
