Does 'knife azure server create' support asynchronous request？ about knife-azure

[muktaa]

Hi,
Yes, all knife server create commands wait for the VM to be created. This
is so implemented to check the status of the server create. Moreover, if
the server create fails in creating the server, the azure knife plugin
deletes the components created, eg- hosted service, storage.
You can run the "knife azure server create" command in background. You can
consider writing a script to create multiple VMs.
You can also consider using Spiceweasel:

Thanks,

Dear all,

I use 'knife azure' to manage my azure infrastructure. But I found 'knife
azure server create' was a synchronous request, which means I must wait for
one VM's creation completed to create a next VM.

Does 'knife azure server create' support asynchronous request? I want to
send multiple 'knife azure server create' request at the same time to
create VMs simultaneously.

Thanks,
Chao Jin

To muktaa,

Thanks for your reply.

I did have used spiceweasel. Spiceweasel can batch loading azure infrastructures from a JSON or YAML file, but It still needs to wait for one VM's creation to create a next VM.

I had tried the command 'parallel' for bulk-node-creation. But an error message appeared below:
" FATAL: Unable to create role:ConflictError : Windows Azure is currently performing an operation with x-ms-requestid 3b0a1e281a2e7b04b9d99edd8c6ca121 on this deployment that requires exclusive access.
ERROR: Failed to create the server -- exception being rescued: exception class/object expected "

I also tried to create one VM in background, and then tried to create another VM, but the same error message showed. I thought it may because chef-server only allows one VM to be created at the a time.

Are there any other approaches can solve this problem? I just hope to fast deploy multiple VMs.

Thanks,
Chao Jin

For asynchronous requests, try using the --bootstrap-protocol cloudapi option or the new knife azurerm server create available on the master branch. ARM commands will get around some limitations in the older API with concurrent requests.
