Upgrading the EKS version

Upgrade the Elastic Kubernetes Service (EKS) version for AWS

AWS frequently updates the EKS version based on new features that are available in the Kubernetes platform. DuploCloud automates this upgrade in the DuploCloud Portal.

IMPORTANT: An EKS version upgrade can cause downtime to your application depending on the number of replicas you have configured for your services. Schedule this upgrade outside of your business hours to minimize disruption.

About the upgrade process

DuploCloud notifies users when an upgrade is planned. The upgrade process follows these steps:

1. A new EKS version is released.

2. DuploCloud adds support for the new EKS version.

3. DuploCloud tests all changes and new features thoroughly.

4. DuploCloud rolls out support for the new EKS version in a platform release.

5. The user updates the EKS version.

Updating the EKS version:

• Updates the EKS Control Plane to the latest version.

• Updates all add-ons and components.

• Relaunches all Hosts to deploy the latest version on all nodes.

After the upgrade process completes successfully, you can assign allocation tags to Hosts.
