Running createNodesInGroup asynchronously

[eyal]

I'm trying to find a way to start the nodes creation and immediately get some information (ip address etc) on the nodes that will be created.

Thereafter I'll start polling the provider to get the status of each node.

I'm currently using EC2 and I need a behaviour similar to the EC2 API runInstances

Any help will be appreciated

Hi Eyal

I think InstanceClient.runInstancesInRegion [1] is what you might be
looking for ;-) Have a look at createlamp [2] for an example of how to
get at the provider-specific EC2 client you need for this.

Hope this helps!

Hi Andrew,

Thanks for your reply

Isn't there a generic jclouds API?

The reason I ask this is that I need this part of code to be generic and provider independent.

There is - ComputeService [1] - but this does not provide a method
that returns as soon as the "create images" *request* has been made,
which seems to be what you're looking for.

I don't know the exact details of *why* such a generic call is not
provided, but would guess that it may not be sufficiently portable
across multiple providers. Hopefully someone on the list can provide
more details.

 Hello again

I have found that TemplateOptions.blockUntilRunning makes the ComputeService asynchronic (when using createNodesInGroup).

It works as expected with EC2 provider but when using HP Cloud I see that the createNodesInGroup is blocked regardless of the value of blockUntilRunning.

Is this a correct behaviour of the ComputeService API?

Would you mind subscribing the new Apache jclouds user group and
resubmitting the question?

See

details.

Thanks!
