Upgrade Emissary-ingress 2.2.X to Emissary-ingress 2.3.1 (YAML)

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

Migration is a two-step process:

  1. Install new CRDs.

    Before installing Emissary-ingress 2.3.1 itself, you need to update the CRDs in your cluster. This is mandatory during any upgrade of Emissary-ingress.

    shell
    kubectl apply -f https://app.getambassador.io/yaml/emissary/2.3.1/emissary-crds.yaml
    kubectl wait --timeout=90s --for=condition=available deployment emissary-apiext -n emissary-system
  2. Install Emissary-ingress 2.3.1.

    After installing the new CRDs, upgrade Emissary-ingress 2.3.1.

    bash
    kubectl apply -f https://app.getambassador.io/yaml/emissary/2.3.1/emissary-emissaryns.yaml && \
    kubectl rollout status -n emissary deployment/emissary-ingress -w
