I am using Cloudify 3.3 and OpenStack Kilo.
After I have successfully installed a blueprint, I tried to scale out the host VM (associated with a floating IP W.X.Y.Z) using the default scale workflow. My expected result is that a new VM will be created with a new floating IP, say A.B.C.D, associated to it.
However, after the scale workflow has been completed, I found that the floating IP W.X.Y.Z has been disassociated from the original host VM while this floating IP has been associated to the newly created VM.
My testing "blueprint.yaml":
tosca_definitions_version: cloudify_dsl_1_2
imports:
- http://www.getcloudify.org/spec/cloudify/3.3/types.yaml
- http://www.getcloudify.org/spec/openstack-plugin/1.3/plugin.yaml
inputs:
image:
description: Openstack image ID
flavor:
description: Openstack flavor ID
agent_user:
description: agent username for connecting to the OS
default: centos
node_templates:
web_server_floating_ip:
type: cloudify.openstack.nodes.FloatingIP
web_server_security_group:
type: cloudify.openstack.nodes.SecurityGroup
properties:
rules:
- remote_ip_prefix: 0.0.0.0/0
port: 8080
web_server:
type: cloudify.openstack.nodes.Server
properties:
cloudify_agent:
user: { get_input: agent_user }
image: { get_input: image }
flavor: { get_input: flavor }
relationships:
- type: cloudify.openstack.server_connected_to_floating_ip
target: web_server_floating_ip
- type: cloudify.openstack.server_connected_to_security_group
target: web_server_security_group
I have tried to create a node_template with type cloudify.nodes.Tier and put all the things inside this container. However, the scale workflow cannot be executed normally in this case.
I wonder what should I do so that the newly created VM can be associated to a new floating IP?
Thanks, Sam
What you are describing is a "one to one" relationship between the node and the resources related to it.
Currently Cloudify does not support this kind of relationship and your blueprint is working just as it should.
This feature will be available as of Cloudify 3.4 that will be released in few months
