Auto delete files in Azure Blob storage

Today I was designing a solution where I had to store files for a certain amount of time in Azure Blob Storage.

I first thought I had to design and build this feature myself but I discovered that this feature is available out of the box through ‘Lifecycle Management’.

Therefore:

  • Open your Storage account on the Azure portal.
  • Go to Lifecycle Management in the Data Management section.
  • Click on Add a rule.
  • The Add a rule wizard is loaded. Specify a rule name and select the applicable blob types. Click on Next.
  • Specify the applicable conditions and the corresponding action. Click on Add to create the Rule.

  • That’s it! 
    • Be aware that it can take up to 48 hours before a new or updated rule

 

Remark: It is also possible to directly use a lifecycle management policy file. This is a collection of rules in a JSON document.

.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...
