Windows Azure Storage: One of the request inputs is out of range

Last week I ran into following error when trying to create a blob storage in Windows Azure:

“One of the request inputs is out of range” 

Let’s have a look at the code who causes this error. Do you see something special?

var blobStorage = storageAccount.CreateCloudBlobClient();
var blobContainer= blobStorage .GetContainerReference(“My Blob Storage”);
blobContainer.CreateIfNotExist();

I didn’t see something wrong.  But when I changed the reference name to “myblobstorage” suddenly everything worked fine. It seems that you cannot use any name you want for Windows Azure Storage containers. I discovered the following naming rules(maybe there are more):

  • use only lower case letters
  • digits are allowed anywhere
  • name should not contain any spaces

A more obvious error message would have been helpful.

.NET 8–Keyed/Named Services

A feature that a lot of IoC container libraries support but that was missing in the default DI container provided by Microsoft is the support for Keyed or Named Services. This feature allows you to register the same type multiple times using different names, allowing you to resolve a specific instance based on the circumstances. Although there is some controversy if supporting this feature is a good idea or not, it certainly can be handy. To support this feature a new interface IKeyedServiceProvider got introduced in .NET 8 providing 2 new methods on our ServiceProvider instance: object? GetKeyedService(Type serviceType, object? serviceKey); object GetRequiredKeyedService(Type serviceType, object? serviceKey); To use it, we need to register our service using one of the new extension methods: Resolving the service can be done either through the FromKeyedServices attribute: or by injecting the IKeyedServiceProvider interface and calling the GetRequiredKeyedServic...

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
