Reconfigure the ElasticSearch Windows Service

If you are running ElasticSearch on a Windows Cluster you probably are using a Windows Service to run it in the background and make it start automatically at boot time.

This Windows Service feature is available out-of-the-box if you use the .zip package.

Some settings of ElasticSearch are managed as command-line arguments(e.g. the min and max memory usage). To manipulate these settings when using the Windows Service, you have to go through the ElasticSearch Windows Service Manager.

  • To open the manager, go the ElasticSearch installation folder. (e.g. c:\elasticsearch-7.4.0\)
  • Browse to the bin folder (where you should find a elasticsearch-service.bat file)
  • Run the following command:
    • elasticsearch-service.bat manager

This will open a GUI where you can manage multiple ElasticSearch settings:

Remark: Most changes will require a restart of the service.

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us.

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
