Day 2 Actions for Tanzu Kubernetes Clusters in vRealize Aria Automation
In this post, we’ll dive deeper into the built-in Day 2 actions available for Tanzu Kubernetes clusters (Workload clusters) in vRealize Aria Automation (vRA). We’ll explore how to scale worker nodes, change the VM class of nodes, and upgrade clusters. These actions can help you manage your TKG clusters more efficiently and effectively.
Scaling Worker Nodes
——————–
To scale a TKG cluster with vRA, follow these steps:
1. Open vRealize Aria Automation and navigate to the “Workload Clusters” view.
2. Select the TKG cluster you want to scale and click on the “Actions” menu.
3. Click on “Scale” and select “Increase” or “Decrease” based on your needs.
4. Choose the number of worker nodes you want to add or remove, and click “Apply”.
After a few minutes, the new worker nodes should be deployed and available in the cluster. If you scale down to two nodes, vRA will power off and delete one of the worker nodes for you.
Changing VM Class of Nodes
—————————
To change the VM class of nodes in a TKG cluster with vRA, follow these steps:
1. Open vRealize Aria Automation and navigate to the “Workload Clusters” view.
2. Select the TKG cluster you want to modify and click on the “Actions” menu.
3. Click on “Change VM Class” and select the new VM class for your worker nodes.
4. vRA will reach out to the namespace to check which VM classes are made available for the namespace. Only these will be available to update to.
5. After a while, two new worker nodes with the updated VM class should be deployed and available in the cluster, and the two old ones should be decommissioned.
Upgrading Clusters
——————-
To upgrade a TKG cluster with vRA, follow these steps:
1. Open vRealize Aria Automation and navigate to the “Workload Clusters” view.
2. Select the TKG cluster you want to upgrade and click on the “Actions” menu.
3. Click on “Upgrade” and select the newest available Kubernetes version for your cluster.
4. After some time, depending on the number of nodes and the size (VM Class) of those nodes, an upgraded cluster with the new Kubernetes version should be available.
In this post, we’ve explored how to use Day 2 actions in vRA to manage Tanzu Kubernetes clusters more efficiently. These actions include scaling worker nodes, changing the VM class of nodes, and upgrading clusters. By leveraging these features, you can streamline your TKG cluster management and keep your clusters up-to-date with the latest Kubernetes versions.
In an upcoming post, we’ll delve deeper into further extensibility abilities for TKG clusters in vRA. Stay tuned!
