ElasticSearch– was created with version [5.3.0] but the minimum compatible version is [6.0.0-beta1]. It should be re-indexed in Elasticsearch 6.x before upgrading to 7.6.1.

As mentioned in some of the previous posts I am migrating an ‘old’ 5.3 instance of ElasticSearch to 7.6.1. In my first (too optimistic) attempt I directly migrated to ElasticSearch 7.6.1.

When starting the ElasticSearch cluster this resulted in the following error message:

[myindex/gTTtwHT3ShiAz-eR94eKmw]] was created with version [5.3.0] but the minimum compatible version is [6.0.0-beta1]. It should be re-indexed in Elasticsearch 6.x before upgrading to 7.6.1.

The trick is to first migrate to ElasticSearch 6.8 and Kibana 6.8. Kibana 6.8 offers an update wizard which guides you through the required steps to upgrade your indices to a supported format.

Here are the steps:

  • Go to Kibana
  • Click on the Management icon on the left
  • Click on the 7.0 Upgrade Assistant
  • Check all the listed issues and apply the suggested solutions
  • When everything is fixed you can safely install ElasticSearch 7.x

.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...
