Kubernetes

WARNING

Currently, Kubernetes is only supported for distribution and deployment of Cluster Controller.

Additional Dovecot Pro components may become supported on Kubernetes in the future. The support policy for Kubernetes MAY change when/if that happens.

Support Policy (Cluster Controller)

To ensure the stability, security, and compatibility of Dovecot Pro components, we adhere to a strict Kubernetes version support policy.

Our software is designed and tested to operate seamlessly on the two most recent versions of Kubernetes prior to the latest Kubernetes stable release.

INFO

The Kubernetes versions supported for a Pro Release is frozen at the time of the release.

For example, if Kubernetes versions 1.29 & 1.28 are supported at the release of Dovecot Pro 3.0.x, those will be the only supported Kubernetes versions for the lifetime of that release.

Support Example

As of the latest update, our software supports the following versions of Kubernetes:

• The latest stable release of Kubernetes minus one version (N-1)
• The latest stable release of Kubernetes minus two versions (N-2)

For example, if the latest stable release of Kubernetes is version 1.30, our software will support:

• Kubernetes version 1.29
• Kubernetes version 1.28
