Built-in Node Types
Abstract Types
The following node_types
are basic types from which concrete types with specific plugin implementations are derived.
-
cloudify.nodes.Root
- The base type for all built-in types. Declares the following interfaces:cloudify.interfaces.lifecycle
: An interface for standard life cycle operations (e.g. create, start, stop, etc.). Operations of this interface are called from the built-in install and uninstall workflows.cloudify.interfaces.validation
: An interface for pre-creation and pre-deletion validation operations. These can be called by using the execute_operation built-in workflow or by a custom workflow.cloudify.interfaces.monitoring
: An interface for monitoring configuration. Operations of this interface are called from the built-in install and uninstall workflows.
-
cloudify.nodes.Tier
- A marker for a future scale group. -
cloudify.nodes.Compute
- A compute resource. Either a virtual or a physical host. -
cloudify.nodes.Container
- A logical partition in a host such as Linux container or Docker. -
cloudify.nodes.Network
- A virtual network. -
clouydify.nodes.Subnet
- A virtual segment of an IP addresses in a network. -
cloudify.nodes.Router
- A virtual layer 3 router. -
cloudify.nodes.Port
- An entry in a virtual subnet. Can be used in some Clouds to secure a static private IP. -
cloudify.nodes.VirtualIP
- A virtual IP implemented as NAT, or in another manner. -
cloudify.nodes.SecurityGroup
- A Cloud security group. (VM network access rules) -
cloudify.nodes.LoadBalancer
- A virtualized load balancer. -
cloudify.nodes.Volume
- A persistent block storage volume. -
cloudify.nodes.FileSystem
- A writable file system. This type must be used in conjunction with acloudify.nodes.Volume
type and acloudify.nodes.Compute
type.- relationships: The conjunction stated above is expressed by specifying two mandatory relationships for the file system.
cloudify.relationships.file_system_depends_on_volume
- Used to format and partition the file system on top of the volume. It creates a single partition occupying the entire capacity of the volume.cloudify.relationships.file_system_contained_in_compute
- Used to mount and unmount the file system from the server.
- properties:
use_external_resource
- Enables the use of already formatted volumes. In this case, the formatting part is skipped, and only a mount point id created. Defaults to False. (Boolean)partition_type
- The partition type. Defaults to 83 which is a Linux native partition. (Integer)fs_type
- The type of the File System. Supported types are:ext2
,ext3
,ext4
,fat
,ntfs
,swap
fs_mount_path
- The path of the mount point.
- Example Usage:
volume_fs: type: cloudify.nodes.FileSystem properties: fs_type: ext4 fs_mount_path: /mount-path relationships: - type: cloudify.relationships.file_system_depends_on_volume target: volume - type: cloudify.relationships.file_system_contained_in_compute target: vm
- relationships: The conjunction stated above is expressed by specifying two mandatory relationships for the file system.
-
cloudify.nodes.ObjectStorage
- A BLOB storage segment. -
cloudify.nodes.SoftwareComponent
- A base type for all middleware level types. -
cloudify.nodes.WebServer
- A Web server.- properties:
port
- The Webserver port.
- properties:
-
cloudify.nodes.ApplicationServer
- An application server. -
cloudify.nodes.DBMS
- A database. -
cloudify.nodes.MessageBugServer
- A message BUS server. -
cloudify.nodes.ApplicationModule
- A base type for any application module or artifact. -
cloudify.nodes.Component
- A base type that represents a connection to a separate deployment unit, which is a part of the application architecture and deployment lifecycle.- properties:
resource_config
:blueprint
:external_resource
: Optional, reuse an already existing blueprint, by default False.id
: This is the blueprint ID that the Component’s node is connected to.blueprint_archive
: blueprint source url available from Cloudify manager (ignored, ifexternal_resource
==True
).main_file_name
: The application blueprint filename. If the blueprint consists of many imported files this is the main blueprint name.
deployment
:id
: This is the deployment ID that the Component’s node is connected to.inputs
: Optional, The inputs to the deployment in the format of a dictionary.logs
: This is a flag for logs and events redirect from the deployment, by default true.auto_inc_suffix
: Optional, will add a suffix to the given deployment ID in the form of an auto incremented index, which is relevant in the scaling a Component node.
executions_start_args
: Optional, params for executions in the format of a dictionary.
client
: Cloudify HTTP client configuration, if empty the current Cloudify manager client will be used.host
: The host name of Cloudify’s manager machine.port
: The port of the REST API service on Cloudify’s management machine.protocol
: The protocol of the REST API service on management machine, defaults to http.api_version
: The version of the Cloudify REST API service.headers
: Headers to be added to the HTTP requests.query_params
: Query parameters to be added to the HTTP request.cert
: Path on the Cloudify manager to a copy of the target Cloudify manager’s certificate.trust_all
: If False, the server’s certificate (self-signed or not) will be verified.username
: Cloudify user username.password
: Cloudify user password.token
: Cloudify user token.tenant
: Cloudify user accessible tenant name.
plugins
: Optional, dictionary of plugins to upload, in which each plugin is in the format: plugin-name: wagon_path: Url for plugin wagon file, plugin_yaml_path: Url for plugin yaml filesecrets
: Optional, dictionary of secrets to set before deploying Components. The format of each secret is: secret-name: value
- properties:
-
cloudify.nodes.ServiceComponent
- A service which is a part of an application deployment. -
cloudify.nodes.SharedResource
- A base type that represents a connection to a separate deployed unit of a resource (shared DB service, filesystem, etc), which is consumed and required by the deployment.- properties:
resource_config
:deployment
:id
: This is the deployment ID that the SharedResource’s node is connected to.
client
: Cloudify HTTP client configuration, if empty the current Cloudify manager client will be used.host
: Host of Cloudify’s manager machine.port
: Port of REST API service on Cloudify’s management machine.protocol
