provision custom nodes

Please follow these steps to provision a custom node-

1. clone this project

2. update config.json to have correct values.

   a. SHIPPABLE_API_TOKEN is your apiToken.

   b. FRIENDLY_NAME is the name of your clusterNode.

   c. IS_SHIPPABLE_INITIALIZED should be set to false, if you want to run the node initialization script yourself. If it is set to true shippable will run the script for you, but before provisioning the node you have to run the command on your node to create a shippable user and ssh authorization(This command is available in your subscriptions/settings/nodes, click on add node and copy the command).

   d. NODE_LOCATION is the IP of your node.

   e. SUBSCRIPTION_ID is the id of subscription for which you want to add this node.

   f. NODE_INIT_SCRIPT is the name of script file. It contains the name of OS and docker version. You can check all the supported OS and docker versions here. An example value is Ubuntu_16.04_Docker_1.13.sh.

3. Install node packages: sudo npm install

4. To provision custom node run node createCustomNode.js. After this completes, node initialization script will be saved in initScript.sh. You can run it on your machine to use it as a Shippable node.
