k3s features and specs

  • Lightweight
    K3s is designed to be lightweight and less resource-intensive compared to full Kubernetes distributions, making it ideal for edge and IoT devices, as well as development environments.
  • Easy Installation
    K3s provides a simple installation process, requiring only a single binary for installation, which simplifies the setup procedure for users.
  • Low Resource Usage
    By stripping away non-essential features, K3s consumes significantly fewer resources, lowering the barrier to entry for running Kubernetes on resource-constrained environments.
  • Fully CNCF Conformant
    K3s is certified by the Cloud Native Computing Foundation (CNCF) as conformant with standard Kubernetes, meaning it follows the same API and operational model.
  • Built-In Database
    K3s includes an embedded SQLite database by default, which simplifies deployment and reduces the complexity associated with managing an external etcd cluster.
  • Automated TLS Management
    K3s has integrated support for TLS certificates management, which helps in ensuring secure communications between components without additional configuration.
  • Ecosystem Compatibility
    K3s supports popular Kubernetes add-ons and CI/CD tools, so it can be seamlessly integrated into existing Kubernetes-based workflows.

Possible disadvantages of k3s

  • Reduced Feature Set
    To keep K3s lightweight, some non-essential Kubernetes features and components are omitted or replaced, which might limit functionality for more advanced use cases.
  • Lack of Scalability
    K3s is optimized for smaller clusters and edge environments, so it may not scale as efficiently as standard Kubernetes distributions in large, enterprise-level deployments.
  • Embedded SQLite Limitations
    While the built-in SQLite database simplifies initial setup, it may not handle high write loads or offer the same reliability and performance as an external etcd cluster for production environments.
  • Community and Enterprise Support
    Although supported by the Kubernetes community, K3s may have less enterprise-grade support and fewer educational resources compared to other full-featured Kubernetes distributions.
  • Ecosystem Integration
    Certain Kubernetes tools or cloud services optimized for full Kubernetes distributions may not work seamlessly with K3s, requiring custom configurations or workarounds.
  • Limited Networking Options
    K3s might have fewer networking configuration options compared to full-featured Kubernetes implementations, potentially restricting advanced network setup.
  • Simplified Security Model
    K3s implements a simplified security model which might lack some advanced security features and policies found in the standard Kubernetes distribution.
