System Requirements for KOTS Apps
This page describes the system requirements for executing and installing KOTS applications. The requirements for command-line-interfaces (such as the Vendor CLI and the KOTS CLI) are described separately, and are not subject to these requirements.
Kubernetes Version Compatibility
Each release of KOTS maintains compatability with the current Kubernetes version, and the 2 most recent versions. This includes support against all patch releases of the corrersponding Kubernetes version.
| KOTS Version | Release Date | Kubernetes Compatibility |
|---|---|---|
| 1.11 | 2020-01-22 | 1.17, 1.16, and 1.15 |
| 1.12 | 2020-02-04 | 1.17, 1.16, and 1.15 |
| 1.13 | 2020-02-27 | 1.17, 1.16, and 1.15 |
| 1.14 | 2020-03-31 | 1.17, 1.16, and 1.15 |
| 1.15 | 2020-05-01 | 1.18, 1.17, and 1.16 |
Existing Cluster Installation Requirements
Existing cluster compatibility is primarily determined through the version of kubernetes running on the cluster. Unless otherwise noted on this page, cluster infrastructure having compatibility for a supported version of Kubernetes will be compatible with Replicated. This excludes any specific and additional requirements imposed by software vendor.
Root access is not required for installations to existing clusters.
Embedded Cluster Installation Requirements
KOTS leverages kURL to embed a new Kubernetes cluster into existing machines. As such, any embedded installation includes additional system requirements (see kURL System Requirements).
Root access is required when for embedded cluster installations.
