KOTS is a comprehensive framework and toolset developed by Replicated that enables the distribution and management of Kubernetes Off-The-Shelf software. Written primarily in Go, KOTS provides both command-line and web-based interfaces for configuring, deploying, and managing third-party Kubernetes applications throughout their lifecycle. The project serves as a critical bridge between software vendors and enterprise Kubernetes environments, automating complex operational tasks that would otherwise require manual intervention.
The core KOTS offering consists of two primary components. The Kots CLI functions as a kubectl plugin that operates client-side to configure and build dynamic Kubernetes manifests. Complementing this is kotsadm, an in-cluster Kubernetes application Admin Console that automates tasks traditionally handled by the CLI, including license verification, application configuration, update management, image renaming, version control for changes, and deployment orchestration. Beyond these core functions, kotsadm also handles preflight checks and support bundle analysis, providing operators with comprehensive visibility into application health and troubleshooting capabilities.
The repository demonstrates active maintenance and community engagement. GitGenius tracking shows a median issue and pull request response latency of approximately 240 hours, with laverya, h4ckersanjith, and jtuchscherer identified as the most active contributors and triagers. The project maintains connections with related repositories including humanlayer/humanlayer, open-telemetry/opentelemetry-go, and k0sproject/k0s through overlapping contributor networks, indicating integration within the broader Kubernetes ecosystem.
KOTS uses MinIO as its default object store for managing application archives and support bundles, with all communication occurring through a REST API under the Apache 2.0 license. Recognizing that MinIO operates under the GNU AGPLv3 license, the project provides flexibility through the optional install flag --with-minio=false, allowing users to deploy KOTS without MinIO dependency. This option is available for both new installations and upgrades, accommodating various deployment scenarios and licensing requirements.
The development environment supports macOS with OrbStack and Kubernetes enabled, as well as Linux platforms. The project includes tooling for real-time development of the kotsadm web component, with changes reflected immediately without manual intervention. For dependency management and package updates, developers can interact directly with the kotsadm-web container using yarn commands. The development setup also provides flexibility for testing different snapshot storage backends, allowing developers to toggle between MinIO and Local Volume Provider paths to validate different production configurations.
Security practices include signed Software Bill of Materials for all Go dependencies, distributed with each release and verifiable using Cosign. The project maintains active documentation at docs.replicated.com and fosters community engagement through the Replicated Community forum and a dedicated #kots channel in the Kubernetes Slack workspace. KOTS is classified across multiple domains including software catalog, Kubernetes operator, application deployment, self-service portal, app lifecycle operations, multi-tenancy, and enterprise software distribution, reflecting its broad applicability across different deployment and operational scenarios.
