Tetrate support is provided for the enterprise and enterprise FIPS editions of TEG under a TEG Subscription. The community edition carries no Tetrate support — see TEG Editions.

TEG Versioning​

TEG follows a semantic versioning model based on https://semver.org. This means we use a MAJOR.MINOR.PATCH version numbering style (e.g. v1.4.0).

This model describes that:

  1. MAJOR version is incremented when incompatible API changes are made.
  2. MINOR version is incremented when new features are added.
  3. PATCH version is incremented when bug and security fixes are handled.

TEG Supported Versions​

The following versions of TEG are currently supported and will receive active bug fixes and security patches under a TEG Subscription:

Kubernetes and Gateway API Support Matrix​

TEG targets specific versions of Kubernetes and the Gateway API; below are the supported versions of Kubernetes and the Kubernetes Gateway API. Note that because the Gateway API is actively evolving, TEG requires relatively current versions of Kubernetes.

Component Version Matrix​

TEG is composed of multiple components: Envoy Gateway, Envoy, Redis, Rate limit service, and the Built on Envoy composer dynamic module (which provides the WAF). The following version of each is used by each version of TEG:

Note that Tetrate does not provide production support for Redis. The Redis instance deployed by the TEG Helm chart is a great way to get started, but it is a single, non-replicated instance with no persistence, no high availability, and no backup, so it should be considered suitable for demo purposes only. For production, bring your own hardened Redis — see Rate Limiting.
