OpenStack Plugin

The OpenStack plugin enables you to use an OpenStack-based cloud infrastructure for deploying services and applications. For more information about OpenStack, see https://www.openstack.org/.

Plugin Requirements

Compatibility

The OpenStack plugin uses various OpenStack client packages. The versions used in the OpenStack plugin are as follows:

OpenStack Configuration

The OpenStack plugin requires credentials and endpoint setup information in order to authenticate and interact with OpenStack.

Providing Credentials as Secrets

It is recommended that you store your credentials as secrets. You can do this using the CLI. Secrets can then be accessed inside your blueprints, as follows:

 external_network:
    type: cloudify.openstack.nodes.Network
    properties:
      openstack_config:
        username: { get_secret: keystone_username }
        password: { get_secret: keystone_password }
        tenant_name: { get_secret: keystone_tenant_name }
        auth_url: { get_secret: keystone_url }
        region: { get_secret: region }
 

Providing Credentials as Environment Variables that are not Stored as Secrets

The OpenStack client suite (Nova, Neutron and so on) will always look for your OpenStack credentials and endpoint setup information in the following order. These values take precedence because this is the default behavior of the client library. It is not recommended that these are included.

  1. Environment variables for each of the configuration parameters.
  2. JSON file at /etc/cloudify/openstack_config.json or at a path specified by the value of an environment variable named OPENSTACK_CONFIG_PATH

On the other hand, the plugin gathers credentials from the following sources, in the following order. This is the supported approach.

Caution

Each source could partially or completely override values gathered from previous ones.

  1. Values specified in the openstack_config property for the node whose operation is currently getting executed (in the case of relationship operations, the openstack_config property of either the source or target nodes will be used if available, with the source’s one taking precedence).
  2. Values specified in the openstack_config runtime property for the node instance whose operation is currently being executed (in the case of relationship operations, the openstack_config property of either the source or target node instances will be used if available, with the source’s one taking precedence).
  3. Values specified in the openstack_config operation input.

Configuration Structure

The openstack_config property can contain the following key-value pairs.

SSL Certificate Validation

When connecting to OpenStack’s endpoint over SSL (which is the typical case), the OpenStack client libraries, by default, perform validation on the certificate presented by OpenStack. The validation is performed against the CA certificates’ bundle used by Python’s requests library. That bundle is provided by the certifi Python library.

SSL validation is being performed (or skipped) as follows:

Logging for OpenStack Libraries

The OpenStack libraries used by the OpenStack plugin perform their own logging using the standard Python logging library.

It is possible to control the visibility of OpenStack API’s logging on Cloudify’s logger by using the logging configuration directive.

The structure of the logging directive is as follows:

logging:
  use_cfy_logger: <boolean> (defaults to true)
  groups:
    nova: <level>
    neutron: <level>
    cinder: <level>
    keystone: <level>
    glance: <level>
  loggers:
    <logger-name>: <level>
    <logger-name>: <level>
    <logger-name>: <level>
    ...

The default logging directive’s value is:

logging:
  use_cfy_logger: true
  groups:
    nova: debug
    neutron: debug
    cinder: debug
    keystone: debug
    glance: debug
  loggers:
    keystoneauth.session: debug

If you specify a logging directive, its contents will be merged with the default.

If use_cfy_logger is true, then a logging handler is added to all applicable OpenStack API loggers (described below) so log records are emitted to the Cloudify logger in addition to any other handlers that may be configured.

The groups section is used to easily set the logging level for groups of loggers, per API. Each such group (nova, neutron) is associated with the list of loggers that belong to the Client class(es) of that particular service.

For example, setting nova to info will result in the following loggers being set to info level:

In addition, you can set the logging level of individual loggers under the loggers section.

Two additional runtime properties are available on node instances of this type after the cloudify.interfaces.lifecycle.start operation succeeds.

cloudify.openstack.nodes.WindowsServer

Derived From: cloudify.openstack.nodes.Server

This type has the same properties and operations mapping as the type above it (because it derives from it). However, it overrides some of the agent and plugin installations operations mapping that is derived from the built-in cloudify.nodes.Compute type. Use this type when working with a Windows server.

In addition, the default value for the use_password property is overridden for this type, and is set to true. If you are using an image with a preset password, change the value to false.

Description: A relationship for connecting a server to a port. The server uses this relationship to automatically connect to the port upon server creation.

Mapped Operations:

cloudify.openstack.port_connected_to_subnet

Description: A relationship for connecting a port to a subnet. This is useful when a network has multiple subnets, and a port must belong to a specific subnet on that network. The port then receives an IP from that specific subnet.

Note that when using this relationship in combination with the port type’s property fixed_ip, the IP must be on the CIDR of the subnet connected to the port.

Note: This relationship has no operations associated with it. The port uses this relationship to automatically connect to the subnet upon port creation.

cloudify.openstack.port_connected_to_floating_ip

Description: A relationship for associating a floating IP with a port. If that port is later connected to a server, the server is accessible via the floating IP.

Common Behaviors of Types

Validations

All types provide the same base functionality for the cloudify.interfaces.validation.creation interface operation:

Runtime Properties

Node instances of any of the types defined in this plugin are set with the following runtime properties during the cloudify.interfaces.lifecycle.create operation:

The only exceptions are the two floating IP types. Because floating-ip objects on OpenStack do not have a name, the external_name runtime property is replaced with the floating_ip_address name, which holds the object’s actual IP address.

Default Resource Naming Convention

When creating a new resource (i.e. use_external_resource is set to false), its name on OpenStack is the value of its resource_id property. However, if this value is not provided, the name defaults to the following schema:

<openstack-resource-type>_<deployment-id>_<node-instance-id>

For example, if a server node is defined as follows:

node_templates:
  myserver:
    type: cloudify.openstack.nodes.Server
    ...

Without setting the resource_id property, the server’s name on OpenStack will be server_my-deployment_myserver_XXXXX (where the XXXXX is the autogenerated part of the node instance’s ID).

Using Existing Resources

You can use existing resources on OpenStack, regardless of whether they were created by a different Cloudify deployment or not via Cloudify at all.

All Cloudify OpenStack types have a property called use_external_resource, which has a default value of false. When set to true, the plugin applies different semantics for each of the operations executed on the relevant node’s instances. Specifically, in the case of the cloudify.interfaces.lifecycle.create operation, rather than creating a new resource on OpenStack of the specified type, the plugin behaves as follows:

  1. Attempts to locate an existing resource on OpenStack for which the name (or IP, in the case of one of the floating-ip types) is the value specified for the resource_id property. If more than one is found, an error is generated.

  2. If no resource is found, the plugin uses the value of the resource_id property to look for the resource by ID. If a resource is still not found, an error is generated.

  3. If a single resource is found, the plugin uses that resource and sets the node instance with the appropriate runtime properties, according to the resource’s data.

The semantics of other operations are also affected, as follows:

Notes

Nova-net Support

The OpenStack plugin includes support for Nova-net mode, meaning an OpenStack installation that does not have the Networking API (Neutron service).

In such an environment, there is only a single preconfigured private network that all servers make use of automatically. There are no subnets, networks, routers or ports. Since these resource types do not exist, the plugin’s equivalent types are not valid for use in such an environment.

However, there are some resource types for which the API is available via both the Nova and the Neutron services. They had originally been on the Nova service and were later moved and received extended implementation in the Neutron service. They were also retained for backward compatibility in the Nova service.

For these resource types the OpenStack plugin defines two separate types. One type is in the plugin’s standard types namespace (cloudify.openstack.nodes.XXX) that uses the newer, extended API via the Neutron service. The other type is in a special namespace (cloudify.openstack.nova_net.nodes.XXX) that uses the older API via the Nova service. You might therefore notice two separate types defined for Floating IP, and for Security Group.

To summarize, ensure that when working in a Nova-net OpenStack environment, Neutron types are not used. These include all types in which the resources’ APIs are natively available only via the Network API, and the types that are in the cloudify.openstack.nova_net.Nodes namespace.

Conversely, when using an OpenStack environment that supports Neutron, it is recommended that you use the Neutron-versions of the relevant types (meaning that you avoid any types defined under the cloudify.openstack.nova_net.Nodes namespace), as they offer more advanced capabilities. However, it’s important to mention that this is not required, and using the Nova-versions of some types in a Neutron-enabled environment is possible and will work as well.

Examples

Example I: Using plugin types and creating relationships

This example demonstrates how to use most of the types in this plugin, and how to create the relationships between them. It creates a server with a security group set on it and a floating IP associated to it, on a subnet in a network.

The following is an excerpt from the blueprint’s blueprint.node_templates section:

my_floating_ip:
  type: cloudify.openstack.nodes.FloatingIP
  interfaces:

    rules:
      - remote_ip_prefix: 0.0.0.0/0
        port: 8080

      type: cloudify.openstack.server_connected_to_floating_ip
    - target: my_security_group
      type: cloudify.openstack.server_connected_to_security_group

Node by Node Explanation

  1. Creates a floating IP with the node name my_floating_ip, and the Ext-Net floating_network_name. (This value represents the name of the external network).

  2. Creates a network with the node name my_network, and the my_network_openstack_name name on OpenStack.

  3. Creates a subnet with the node name my_subnet, and the my_subnet_openstack_name name on OpenStack. The subnet’s address range is defined as 1.2.3.0 - 1.2.3.255 using the cidr parameter, and the subnet’s IP version is set to version 4. The subnet will be set on the my_network_openstack_name network because of the relationship to the my_network node.

  4. Creates a security_group with the node name my_security_group, and the my_security_group_openstack_Name name on OpenStack. The security group is set with a single rule, that allows all traffic (Because the address range 0.0.0.0/0 is used) to port 8080. (The default direction is ingress).

  5. Creates a server with the node name my_server, and the my_server_openstack_name name on OpenStack. The server is set with an image and flavor IDs. The server is set with multiple relationships:

    • A relationship to the my_network node. Through this relationship, the server is automatically placed on the my_network_openstack_name network.
    • A relationship to the my_subnet node. This relationship is strictly for ensuring the order of creation is correct because the server requires the my_subnet_openstack_name subnet to exist before it can be created on it.
    • A relationship to the my_floating_ip node. This designated relationship type is responsible for associating the server with the floating IP represented by the my_floating_ip node.
    • A relationship with the my_security_group node. This relationship is responsible for setting the server up with the security group that is represented by the my_security_group node.

Example II: Using the router and port types

This example demonstrates how to use the router and port types, and some of the relationships that were not included in example I. It creates a server connected to a port, in which the port is set on a subnet in a network and has a security group set on it. Finally, it shows how this subnet connects to a router and from there to the external network.

Following is an excerpt from the blueprint’s blueprint.node_templates section:

            flavor: 101
  relationships:
    - target: my_port
      type: cloudify.openstack.server_connected_to_port

Node by Node Explanation

  1. Creates a network. See example I for more information.

  2. Creates a security group. See example I for more information.

  3. Creates a subnet. This is similar to that in example I, but in this example the subnet has an additional relationship set towards a router.

  4. Creates a port, with the node name my_port, and the name my_port_openstack_name on OpenStack. The port is set with multiple relationships:

    • A relationship to the my_network node. Through this relationship, the port will be automatically placed on the my_network_openstack_name network.
    • A relationship to the my_subnet node. This relationship is strictly for ensuring the correct order of creation, becaue the port requires that the my_subnet_openstack_name subnet exists before it can be created on it.
    • A relationship to the my_security_group node. This designated relationship type manages the setting of the my_security_group_openstack_name security group on the port.
  5. Creates a router, with the node name my_router and the my_router_openstack_name name on OpenStack. The router will automatically have an interface in the external network.

  6. Creates a server, with the node name my_server, and the the node’s ID name (because no name parameter was supplied under the server property) on OpenStack.
    The server is set with an image and flavor IDs. It also overrides the cloudify_agent property of its parent type, to set the username that will be used to connect to the server for installing the Cloudify agent on it. Finally, it is set with a relationship to the my_port node. This designated relationship type manages connecting the server to my_port_openstack_name.

Example III: Using the volume type

This example demonstrates how to use the volume type, and the volume_attached_to_server relationship.

Following is an excerpt from the blueprint’s blueprint.node_templates section.

my_server:
  type: cloudify.openstack.nodes.Server
  properties:
    cloudify_agent:
      user: ubuntu
  interfaces:
    cloudify.interfaces.lifecycle:
      create:
        inputs:
          args:
            image: 8672f4c6-e33d-46f5-b6d8-ebbeba12fa02
            flavor: 101
    cloudify.interfaces.validation:
      creation:
        inputs:
          args:
            image: 8672f4c6-e33d-46f5-b6d8-ebbeba12fa02
            flavor: 101

my_volume:
  type: cloudify.openstack.nodes.Volume
  properties:
    resource_id: my_openstack_volume_name
    device_name: /dev/vdb
  interfaces:
    cloudify.interfaces.lifecycle:
      create:
        inputs:
          args:
            size: 1
  relationships:
    - target: my_server
      type: cloudify.openstack.volume_attached_to_server

Node by Node Explanation

  1. Creates a server, with name my_server, and with name on OpenStack the node’s ID (since no name parameter was supplied under the server property). The server is set with an image and flavor IDs.
  2. Creates a volume. It is set with a relationship to the my_server node: This designated relationship type will take care of attaching the volume to OpenStack server node.

Example IV: Using Windows server with a Cloudify agent

This example demonstrates how to use a Windows server on which a Cloudify agent is deployed.

Node by Node Explanation

  1. Creates a keypair. The private key is saved under /tmp/windows-test.pem.
  2. Creates a Windows server.
    • It is set with a relationship to the my_keypair node, which makes the server use the it as a public key for authentication, and also makes it use this public key to encrypt the password before posting it to the OpenStack metadata service.
    • The worker-installer interface operations are supplied with values for the user and password for the cloudify_agent input. The password uses the get_attribute feature to retrieve the decrypted password from the Server’s runtime properties. (Note that in this example, only the install operation was supplied with this input, but all of the worker installer operations and the plugin installer operations should be supplied with it).
    • Custom userdata is defined that configures WinRM and installs Python on the machine (Windows Server 2012 in this example) after it is up. This is required for the Cloudify agent to be installed on the machine.
