Upgrade Emissary-ingress 3.4.Z (YAML)

Since Emissary-ingress's configuration is entirely stored in Kubernetes resources, upgrading between versions is straightforward.

Resources to check before migrating to 3.8.1.

Emissary-ingress 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.

    Before installing Emissary-ingress 3.8.1 itself, you need to update the CRDs in your cluster. This is mandatory during any upgrade of Emissary-ingress.

  2. Install Emissary-ingress 3.8.1.

    After installing the new CRDs, upgrade Emissary-ingress 3.8.1.
