Heat templates and Quantum resources
Hi all,
I have some questions regarding the integration of Quantum in Heat:
- I haven't found a way to attach an instance resource to a Quantum port
that already exists. Is it possible?
- When I create a Quantum port in my template and binds the instance to
that port, why does Heat still create an additional port to the
tenant-owned network?
I have created a very simple template to test:
{
"AWSTemplateFormatVersion" : "2010-09-09",
"Description" : "Test creation of Quantum resources with a very simple
instance",
"Parameters" : {
"KeyName" : {
"Description" : "Name of an existing EC2 KeyPair to enable SSH access
to the instances",
"Type" : "String"
},
"NetworkUuid" : {
"Description" : "Network UUID",
"Type" : "String"
},
"SubnetUuid" : {
"Description" : "Network UUID",
"Type" : "String"
}
},
"Resources" : {
"QuantumPort": {
"Type": "OS::Quantum::Port",
"Properties": {
"network_id": { "Ref" : "NetworkUuid" },
"device_id": { "Ref": "CirrosInstance" },
"fixed_ips": [{
"subnet_id": { "Ref" : "SubnetUuid" },
"ip_address": "10.0.0.100"
}]
}
},
"DefaultSecurityGroup" : {
"Type" : "AWS::EC2::SecurityGroup",
"Properties" : {
"GroupDescription" : "Enable ICMP plus SSH access",
"SecurityGroupIngress" : [
{"IpProtocol" : "icmp", "FromPort" : "-1", "ToPort" : "-1",
"CidrIp" : "0.0.0.0/0"},
{"IpProtocol" : "tcp", "FromPort" : "22", "ToPort" : "22",
"CidrIp" : "0.0.0.0/0"}
]
}
},
"CirrosInstance": {
"Type": "AWS::EC2::Instance",
"Properties": {
"ImageId" : "cirros-0.3.0-x86_64-uec",
"InstanceType" : "m1.nano",
"KeyName" : { "Ref" : "KeyName" },
"SecurityGroups" : [ {"Ref" : "DefaultSecurityGroup"} ]
}
}
},
"Outputs" : {
"InstanceIPAddress" : {
"Value" : { "Fn::GetAtt" : ["CirrosInstance", "PrivateIp"] },
"Description": "Private IP address of the instance"
}
}
}
For my tests, I use devstack and the Open vSwitch plugin. After the stack
is created, the instance is up and running but it is connected to 2 ports:
$ heat stack-show cirros
