Hi All,
I currently try to extend the docker driver. The final result should
be that a user can specify a host folder which should be mounted into
the docker container.
for testing I have specified some custom metadata in heat like:
HeatTemplateFormatVersion: '2012-12-12'
Parameters: {}
Mappings: {}
Resources:
busybox:
Type: OS::Nova::Server
Properties:
flavor: m1.small
image: busybox:latest
metadata:
Volumes: "/tmp:/tmp/"
When I try to read the metadata in the docker driver
(/usr/lib/python2.6/site-packages/nova/virt/docker/driver.py) from the
given instance object then I get something like:
instance['metadata']
[{
u'instance_uuid': u'7bc909c4-76d4-42d3-812d-310095f28757',
u'deleted': 0,
u'created_at': u'2013-11-20T10:16:14.000000',
u'updated_at': None,
u'value': u'/tmp:/tmp',
u'key': u'Volumes',
u'deleted_at': None,
u'id': 56
}]
Please note that the map does not container "Volumes: /tmp:/tmp" but a
"value" and a "key" key.
To access the needed value I have to:
instance['metadata'][0]['value']
instead of:
instance['metadata'][0]['Volumes']
Is that a bug in heat or is my template wrong?
does anybody else use the metadata section in a heat template?
thank you,
Daniel
