##Using the Openstack Orchestration provider

Creating a client is straight-forward:

  var openstack = pkgcloud.orchestration.createClient({
    provider: 'openstack', // required
    username: 'your-user-name', // required
    password: 'your-password', // required
    authUrl: 'your identity service url' // required
  });

Note: Due to variances between OpenStack deployments, you may or may not need a region option.

More options for creating clients

API Methods

Stacks

client.getStacks([options], callback)

Lists all stacks that are available to use on your Openstack account

Callback returns f(err, stacks) where stacks is an Array

client.createStack(options, callback)

Creates a stack with the options specified.

Options are as follows:

{
  name: 'my-stack-name', // required
  timeout: 30,    // timeout, in minutes, required
  templateUrl: 'http://path.to.some.openstack.heat.template', // required, unless you pass template directly
  template: { ... }, // optional, unless you don't provide templateUrl
  parameters: { ... },  // optional parameters for the stack
  environment: { ... },  // optional environment values for the stack
  files: { ... }, // optional files for the stack
}

Returns the stack in the callback f(err, stack)

client.getStack(stack, callback)

Retrieves the provided stack or stackId from the service. Callback has the signature f(err, stack).

Result stack-object includes following fields

{
  id: ,
  name: ,
  status: ,
  description: ,
  templateDescription: ,
  statusReason: ,
  owner: ,
  disableRollback: ,
  parameters: ,
  capabilities: ,
  notificationTopics: ,
  timeout: ,
  createdAt: ,
  updatedAt: ,
  outputs:  // Outputs field has value only if outputs are defined in template and the stack has been instantiated.  
}

client.previewStack(details, callback)

Identical to the client.createStack() call, except it only previews the creation, instead of actually provisioning the stack.

Returns the previewed stack in the callback f(err, stack)

client.adoptStack(details, callback)

Identical to the client.createStack() call, except it requires passing details.stackData which is the abandonedStack value returned from client.abandonStack().

Returns the created stack in the callback f(err, stack)

client.updateStack(stack, callback)

Update the provided stack.

The following values from the provided stack are updatable.

{
  name: 'my-stack-name', // required
  timeout: 30,    // timeout, in minutes, required
  templateUrl: 'http://path.to.some.openstack.heat.template', // required, unless you pass template directly
  template: { ... }, // optional, unless you don't provide templateUrl
  parameters: { ... },  // optional parameters for the stack
  environment: { ... },  // optional environment values for the stack
  files: { ... }, // optional files for the stack
}

client.deleteStack(stack, callback)

Delete the created stack, and delete the resources. Callback is f(err).

client.abandonStack(stack, callback)

Delete the created stack, but leave the resources running. Will callback with f(err, abandonedStack) where the abandonedStack would be passed in as an option to client.createStack().

client.getTemplate(stack, callback)

Get the template for a provided stack. Will callback with f(err, template).

Resources

client.getResource(stack, resource, callback)

Get the resource for a provided stack and resource or resourceName in the callback f(err, resource)

client.getResources(stack, [options], callback)

Get the resources for a provided stack. Callback is f(err, resources).

Options are as follows:

{
  nestedDepth: 3 // include resources from nested stacks up to nestedDepth levels of recursion
}

client.getResourceTypes(callback)

Get a list of valid resource types. Callback is f(err, resourceTypes).

client.getResourceSchema(resourceType, callback)

Get the schema for a provided resourceType. Callback is f(err, resourceSchema).

client.getResourceTemplate(resourceType, callback)

Get the template for a provided resourceType. Callback is f(err, resourceTemplate).

Events

client.getEvent(stack, resource, eventId, callback)

Get the event for a provided stack, resource and eventId.

f(err, event)

client.getEvents(stack, callback)

Get all of the events for a provided stack

f(err, events)

client.getResourceEvents(stack, resource, callback)

Get all of the events for a stack and resource.

f(err, events)

Templates

client.validateTemplate(template, callback)

Validates a provided template, with a callback of f(err, template).
