OperationTimedOut on Microsoft.DBforMySQL/servers arm deployment - azure-resource-manager

Question

I've been trying to deploy the following arm template (removed the resources that are deploying successfully for brievety) a couple of times now.
I'm always getting the following error on the MySQL deployment part.
New-AzureRmResourceGroupDeployment : 9:21:31 AM - Resource Microsoft.DBforMySQL/servers 'webarm01' failed with
message '{
"status": "Failed",
"error": {
"code": "ResourceDeploymentFailure",
"message": "The resource operation completed with terminal provisioning state 'Failed'.",
"details": [
{
"code": "OperationTimedOut",
"message": "The operation timed out and automatically rolled back. Please retry the operation."
}
]
}
}'
Here is the arm template

My question: how can I deploy a MySQL server, + databases using arm without running in a timeout?

Answer 1

After some internal discussions with Microsoft it appears that even though the administratorLoginPassword parameter is tagged typed as secure string you are supposed to pass in a clear text password.
The secure string will be too long and make the deployment hang.
Microsoft is working on better error messages and eventually supporting secure strings properly.
Also some parameters might be conflicting, here is an updated template that works for me.
