--- title: Helm Version Requirements --- This section contains the requirements for Helm, which is the tool used to install Rancher on a high-availability Kubernetes cluster. ## Identifying the Proper Helm v3 Version Select any Helm v3 version that is officially compatible with the Kubernetes version range you are using from our [Rancher Support Matrix](https://www.suse.com/suse-rancher/support-matrix/all-supported-versions). To apply this rule, you may need to reference two external resources: - **Helm Version Compatibility:** Refer to the [Helm Version Support Policy](https://helm.sh/docs/topics/version_skew/) and select the version matching the rule for your Rancher minor target. - **Rancher's Kubernetes Support Range:** Use the [Rancher Support Matrix](https://www.suse.com/suse-rancher/support-matrix/all-supported-versions) to identify the Kubernetes versions supported by your target Rancher minor version. ### Example - **Scenario:** You are targeting Rancher v2.11.4, which supports Kubernetes versions 1.30 through 1.32. - **Application:** Our rule requires a Helm version that supports this range. You can verify this by checking the Helm version's compatibility with the highest version in the range, Kubernetes v1.32. - **Result:** You find that both Helm v3.17 and Helm v3.18 support the Kubernetes v1.30-v1.32 range. - Although both work, we recommend Helm v3.18 because it is the newest Helm minor version overlapping the supported Kubernetes range. ## Additional Notes - Helm v3.2.x or higher is required to install or upgrade Rancher v2.5. - When using tools that run Helm commands for you (like Terraform), you must make sure they are configured to use the correct Helm version.
