Introduction#

Aspen Mesh is built on two primary open source projects:

  • Istio, a service mesh for Kubernetes

  • Envoy, an edge and service proxy designed for cloud-native applications

About the Aspen Mesh documentation#

The Aspen Mesh documentation is a supplement to—not a replacement for—the Istio and Envoy documentation. If you can’t find the information you need in the Aspen Mesh documentation, see the Istio and Envoy documentation.

Where to find the Istio documentation#

The Istio documentation is located here:

https://istio.io/latest/docs/

Where to find the Envoy documentation#

The Envoy documentation is located here:

https://www.envoyproxy.io/docs/envoy/latest/

About links to Istio and Envoy documentation#

Links in the Aspen Mesh documentation to Istio and Envoy documentation take you to the documentation for the latest versions of those products, but you can adjust the URLs to see the documentation for your version of Aspen Mesh.

Adjust an Istio-documentation URL for your version of Aspen Mesh#

  • Replace latest in the URL with the letter v followed by the minor version of Aspen Mesh.

    Example

    v1.14

Adjust an Envoy-documentation URL for your version of Aspen Mesh#

  • Replace latest in the URL with the letter v followed by the version of the Istio proxy (Envoy) shown in the release notes for your version of Aspen Mesh.

    Example

    v1.22.0

    If the Aspen Mesh release notes don’t specify the patch version (the third number—0 in the example), see the Envoy version history to determine a patch version that you can use to create a valid URL.
