I am working with the OS::Nova::Server resource and looking at the tests
[1], it should be possible to just define 'swap_size' and get a swap
space created on the instance:
NovaCompute:
type: OS::Nova::Server
properties:
image:
{get_param: Image}
...
block_device_mapping_v2:
- swap_size: 1
When trying this the first thing I hit is a validation code nit that is
already fixed @ [2] (I have slightly older heat) and I applied that fix.
However, when I try and deploy with a Flavor that has a 2MB swap for
example, and with the above template, I still end up with a 2MB swap.
Am I right in my assumption that the above template is the equivalent of
specifying --swap on the nova boot cli (i.e. should this work?)? I am
working with the Ironic nova driver btw and when deploying using the
nova cli using --swap works; has anyone used/tested this property
recently? I'm not yet sure if this is worth filing a bug for yet.
thanks very much for reading! marios
