Implement Magnum resources

https://blueprints.launchpad.net/heat/+spec/magnum-resources

This Blueprint proposes to add support for Magnum resources.

Problem description

Magnum is a container management service that is currently not supported by Heat. Resources will be added to Heat to support:

  • Baymodel, An object stores template information about the bay which is used to create new bays consistently.
  • Bay, A collection of node objects where work is scheduled.
  • Pod, A collection of containers running on one physical or virtual machine.
  • Service, An abstraction which defines a logical set of pods and a policy by which to access them.
  • ReplicationController, An abstraction for managing a group of PODs to ensure a specified number of PODs are running.
  • Node, A baremetal or virtual machine where work executes
  • Container, A docker container

Proposed change

Magnum resources are not integrated, so they will be added to contrib directory.

Magnum client plugin will be added for communication with Magnum, which has his own requirements. Following resources will be added:

Add the OS::Magnum::BayModel resource

resources:
  model:
    type: OS::Magnum::BayModel
    properties:
      name: String
      image: String
      keypair: String
      external_network: String
      dns_nameserver: String
      flavor: String
      docker_volume_size: Int
      network_driver: String
      http_proxy: String
      https_proxy: String
      no_proxy: String
      labels: String
      insecure: Boolean

Add the OS::Magnum::Bay resource

resources:
  bay:
    type: OS::Magnum::Bay
    properties:
      name: String
      baymodel: { get_resource: model }
      node_count: Int
      discovery_url: String
      bay_create_timeout: Int

Add the OS::Magnum::Pod resource

resources:
  pod:
    type: OS::Magnum::Pod
    properties:
      bay: { get_resource: bay }
      manifest: SOFTWARE_CONFIG
      manifest_url: String

Add the OS::Magnum::Service resource

resources:
  service:
    type: OS::Magnum::Service
    properties:
      bay: { get_resource: bay }
      manifest: SOFTWARE_CONFIG
      manifest_url: String

Add the OS::Magnum::ReplicationController resource

resources:
  rc:
    type: OS::Magnum::ReplicationController
    properties:
      bay: { get_resource: bay }
      manifest: SOFTWARE_CONFIG
      manifest_url: String

Add the OS::Magnum::Node resource

resources:
  rc:
    type: OS::Magnum::Node
    properties:
      name: String
      type: String
      image: String

Add the OS::Magnum::Container resource

resources:
  rc:
    type: OS::Magnum::Node
    properties:
      name: String
      type: String
      command: String
