Removing Node From Cluster in Rancher

Learn how to remove node from cluster in Rancher.

Removing a node from a cluster in Rancher can be a straightforward process if done correctly. Rancher is a popular open-source platform for managing containers and Kubernetes clusters.

There are two ways to remove a node from a Rancher cluster:

1) Removing a node through the Rancher UI:
* Log in to the Rancher UI.
* Select the cluster that contains the node you want to remove.
* Click on the "Nodes" tab.
* Find the node you want to remove and click on it.
* In the "Node Details" page, click on the "Actions" button.
* Select "Drain Node" from the drop-down menu.
* Follow the instructions to drain the node, which involves evacuating the workloads from the node and removing it from the cluster.
* Once the node has been drained, click on the "Delete" button in the "Node Details" page.
* Confirm the deletion of the node.

2) Removing a node through the Rancher CLI:
* Log in to the Rancher CLI.
* Run the following command to drain the node:
In CSS
rancher node drain [node-name]
* Run the following command to delete the node:
In BASH
rancher node rm [node-name]

It's important to note that removing a node from a Rancher cluster can impact the availability of the workloads running on that node. Before removing a node, it's recommended to make sure that the workloads have been successfully evacuated and that the cluster has enough resources to accommodate the remaining nodes.

In conclusion, removing a node from a Rancher cluster can be done through the UI or the CLI, and it's important to follow the proper steps to ensure a smooth process and minimize the impact on the workloads.
