Uninstall in an air-gapped Embedded Cluster environment

To completely remove an Embedded Cluster and all associated applications, each node in the cluster must be individually reset. This operation is especially useful during development, after configuration issues, or when reusing existing hardware.

Reset implications Copied

• Resetting a node removes the entire cluster configuration and application data from that machine.
• All OpenEBS Persistent Volume Claims (PVCs) on the node will be deleted during reset.
  • Only PVCs created via StatefulSets will be automatically recreated on another node.
  • Other PVCs require manual redeployment of the application to recreate them.

Reset a node Copied

1. SSH into the node you want to reset. Ensure the Embedded Cluster binary used to manage the Embedded Cluster is still available on the machine.

2. Run the following command to reset the node and trigger an automatic reboot:

   sudo ./itrs-analytics reset
   

3. (Optional) Use additional flags:

   • --no-prompt: Suppresses any interactive confirmation prompts.
   • --force: Forces the reset by ignoring encountered errors.

   This command resets the node and reboots it to ensure all temporary and persistent configurations related to the cluster are removed.
