Upgrading the EKS version
Upgrade the Elastic Kubernetes Service (EKS) version for AWS
AWS frequently updates the version of EKS 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.
The upgrade process:
- Updates the EKS Control Plane to the latest version
- Relaunches all Hosts to deploy the latest version on all nodes.
After the upgrade process completes successfully, you optionally assign allocation tags to Hosts.
To upgrade the EKS version, in the DuploCloud Portal:
- 1.Click Administrator -> Infrastructure.
- 2.Select the Infrastructure that you want to upgrade to the latest EKS version.
- 3.Select the EKS tab. If an Infrastructure upgrade is available, an Upgrade link appears in the Value column.
EKS tab with Upgrade available - 4.Click the Upgrade link. The Upgrade EKS Cluster pane displays.
