File Plugin

These features are part of the utilities plugin.

Cloudify Utilities: Files Plugin

The files utility allows you to package a file with a blueprint and move it onto a managed Cloudify Compute node.

Node types:

cloudify.nodes.File

Derived From: cloudify.nodes.Root

This is node type that describes the file to transfer.

Properties:

resource_config - a dictionary that represent the file resource.

type: cloudify.datatypes.File

required: true

cloudify.datatypes.File structure (from plugin.yaml):

  cloudify.datatypes.File:
    properties:
      resource_path:
        type: string
        description: >
          The path relative to the blueprint where the file is stored.
          Currently this must be packaged in the blueprint. An external URI is
          not valid.
        required: true
      file_path:
        type: string
        description: >
          The path on the machine where the file should be saved.
        required: true
      owner:
        type: string
        description: >
          The owner string, such as "centos:wheel"

      mode:
        type: integer

Examples:

Add a repo file to a VM:

Blueprint Node Template:

  docker_yum_repo:
    type: cloudify.nodes.File
    properties:
      resource_config:
        resource_path: resources/docker.repo
        file_path: /etc/yum.repos.d/docker.repo
        owner: root:root
        mode: 644

Note: For file transfer to a remote host defined in the blueprint, use cloudify.relationships.contained_in relationship (see openstack-blueprint.yaml example).
