+# Harvester Overcommit Update Script
+A simple Bash script for updating all the VMs in a Harvester cluster with the current overcommit settings. This script obtains the current overcommit settings and iterates over all the VMs to get the CPU & Memory Limits and sets the CPU & Memory requests & limits.
+
+## Setup
+1. Edit the `update_overcommit.sh` file and replace the following line with the path to your KUBECONFIG file.
+```
+export KUBECONFIG=<path_to_kubeconfig>
+```
+
+2. Make the script executable
+```
+chmod +x ./update_overcommit.sh
+```
+
+3. Run the script
+```
+sh ./update_overcommit.sh
+```
