Upgrade Ambassador Edge Stack 3.3.Z to Ambassador Edge Stack 3.4.0 (YAML)

Since Ambassador Edge Stack's configuration is entirely stored in Kubernetes resources, upgrading between versions is straightforward.

Resources to check before migrating to 3.4.0.

Ambassador Edge Stack 3.4 has been upgraded from Envoy 1.23 to Envoy 1.24.1 which removed support for the LightStep tracing driver. The team at LightStep and the maintainers of Envoy-Proxy recommend that users instead leverage the OpenTelemetry Collector to send tracing information to LightStep. We have written a guide which can be found here Distributed Tracing with OpenTelemetry and Lightstep that outlines how to set this up. It is important that you follow this upgrade path prior to upgrading or you will drop tracing data.

Migration Steps

Migration is a two-step process:

  1. Install new CRDs.

    After reviewing the changes in 3.x and confirming that you are ready to upgrade, the process is the same as upgrading minor versions in previous version of Ambassador Edge Stack and does not require the complex migration steps that the migration from 1.x tto 2.x required.

    Before installing Ambassador Edge Stack 3.4.0 itself, you need to update the CRDs in your cluster. This is mandatory during any upgrade of Ambassador Edge Stack.

  2. Install Ambassador Edge Stack 3.4.0.

    After installing the new CRDs, upgrade Ambassador Edge Stack 3.4.0:
