Manual install of the Java JRE

Today I had to install the Java JRE on a server to be able to use ElasticSearch. Unfortunately I couldn’t install any software that allowed me to extract and run the tar.gz file on the server.

Here is my workaround:

Download and extract

  • Start by downloading the Java 8 Server JRE.
  • Once downloaded, unzip the tar.gz file. You’ll get a tar file.
  • That tar file should be unzipped again. The output of this second unzip operation was a set of binaries and executables.
  • Copy these files over to a file share on the target server.

Installation

  • Create a folder C:\Program Files\Oracle Java Server on your server.
  • Browse to the content of the file share.  Go one level deeper e.g. jdk1.8.0_XX (where XX is the current update version) and copy this content to the new folder on your server.

Set JAVA_HOME environment variable

Finally we need to set an environment variable to point to our new Java installation:

  • Open the System Properties.
  • Click the Advanced tab and the Environment Variables button.
  • Click New... at the System Variables.
  • Use JAVA_HOME as the name of the variable and the path C:\Program Files\Oracle Java Server as the value.
  • Finish this job by clicking OK until your are back at the control panel.

That’s it!

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...
