coreos-cluster

coreos-cluster

Create a fully functional core-os cluster on Rackspace Cloud from any node.js application. A command-line version of coreos-cluster is available on npm as coreos-cluster-cli.

Quick Example

var cluster = require('coreos-cluster');

cluster.createCluster({
  size: 10,
  type: 'performance',
  version: 'beta',
  keyname: 'my-ssh-keyname'
}, function(err, results) {
  // will callback with a functional cluster
});

Options

• size - Optional. Size of the cluster in nodes, minimum/default of 3
• type - Optional. performance or onMetal servers, defaults to performance vms
• version - Optional. coreos version: stable (default), beta or alpha
• keyname - Optional. Rackspace Cloud Servers SSH keyname. If not provided, will create a new ssh key and include in the results
• flavor - Optional. The Rackspace Cloud Servers flavor. Defaults to performance1-1 flavor for performance and onmetal-compute1 for onMetal

Rackspace Cloud Credentials

coreos-cluster is built on pkgcloud@1.0.0 and will now make use of environment variables for the Rackspace credentials:

• PKGCLOUD_RACKSPACE_USERNAME - Your rackspace username
• PKGCLOUD_RACKSPACE_APIKEY - API Key for your account
• PKGCLOUD_RACKSPACE_PASSWORD - Password may be used in lieu of API key
• PKGCLOUD_RACKSPACE_REGION - Region for the coreos cluster
• PKGCLOUD_RACKSPACE_AUTH_URL - Optional. Use an alternate authentication endpoint. See the Rackspace Endpoints for more endpoint information.
• PKGCLOUD_RACKSPACE_USE_INTERNAL - Optional. Use the local service interface if calling from a Rackspace cloud server

Installation

npm install coreos-cluster

Next Steps

As coreos-cluster is built on pkgcloud, the next step is to add a provider option that allows you to use different compute providers within pkgcloud.
