Mapping using hostname does not work

[ericfuxealth]

Describe the bug Using "hostname" in mapping does not work, but "host" works.

To Reproduce Steps to reproduce the behavior:

1. Install emissary-ingress using helm chart:

   
   helm repo add datawire https://app.getambassador.io
   helm repo update
   kubectl apply -f https://app.getambassador.io/yaml/emissary/3.3.0/emissary-crds.yaml
   kubectl wait --timeout=90s --for=condition=available deployment emissary-apiext -n emissary-system

helm install -n emissary --create-namespace \ emissary-ingress datawire/emissary-ingress && \ kubectl rollout status -n emissary deployment/emissary-ingress -w

2. Notice deployment " emissary-ingress-agent" and "emissary-ingress" are using different version of the image: 

apiVersion: apps/v1 kind: Deployment metadata: name: emissary-ingress-agent namespace: default labels: app.kubernetes.io/name: emissary-ingress-agent helm.sh/chart: emissary-ingress-8.3.0 app.kubernetes.io/instance: emissary-ingress app.kubernetes.io/part-of: emissary-ingress app.kubernetes.io/managed-by: Helm product: aes spec: ... spec: serviceAccountName: emissary-ingress-agent containers:

• name: agent image: docker.io/emissaryingress/emissary:3.1.0 ... apiVersion: apps/v1 kind: Deployment metadata: name: emissary-ingress namespace: default labels: app.kubernetes.io/name: emissary-ingress helm.sh/chart: emissary-ingress-8.3.0 app.kubernetes.io/instance: emissary-ingress app.kubernetes.io/part-of: emissary-ingress app.kubernetes.io/managed-by: Helm product: aes spec: replicas: 3 selector: matchLabels: app.kubernetes.io/name: emissary-ingress app.kubernetes.io/instance: emissary-ingress strategy: type: RollingUpdate

  progressDeadlineSeconds: 600 template: metadata: labels: app.kubernetes.io/name: emissary-ingress helm.sh/chart: emissary-ingress-8.3.0 app.kubernetes.io/instance: emissary-ingress app.kubernetes.io/part-of: emissary-ingress app.kubernetes.io/managed-by: Helm product: aes profile: main ... containers:

  • name: emissary-ingress image: docker.io/emissaryingress/emissary:3.3.0

    
    3. Configure a mapping using "hostnmae"
    Observe the mapping doesn't work

4. Change the mapping to use "host" Observe the mapping now works.

Expected behavior Routing using the mapping should work.

Versions (please complete the following information):

• Ambassador: [e.g. 3.3.0]
• Kubernetes environment: EKS
• Version: 1.23

Additional context Add any other context about the problem here.

Additionally, "hostname" in Host doesn't work.

The following configuration fails to work:

apiVersion: getambassador.io/v3alpha1
kind: Listener
metadata:
  name: emissary-ingress-listener-8443
  namespace: emissary
spec:
  port: 8443
  protocol: HTTPS
  securityModel: SECURE
  hostBinding:
    namespace:
      from: ALL
    selector:
      matchLabels:
        external-hosts: "true"
---
apiVersion: getambassador.io/v3alpha1
kind: Host
metadata:
  name: host-external
  namespace: emissary
  labels:
    external-hosts: "true"
spec:
  hostname: "server.example.com"  <<<<<<<<< Removing this line it will work.
  acmeProvider:
    authority: none
  tlsSecret:
    name: emissary-selfsigned-cert
    namespace: emissary
  selector:
    matchLabels:
      external-mapping: "true"
---
apiVersion: getambassador.io/v2
kind: Mapping
metadata:
  name: server
  namespace: emissary
  labels:
    external-mapping: "true"
spec:
  # host: "server.example.com"
  prefix: /
  service: server:3002

When "hostname" is removed from Host and "host" is enabled in Mapping it will start working.

Update: once I started using "apiVersion: getambassador.io/v3alpha1" for Mapping, the "hostname" field does work.

However, "hostname" field in Host still does not work.

This is the updated code:

apiVersion: getambassador.io/v3alpha1
kind: Listener
metadata:
  name: emissary-ingress-listener-8443
  namespace: emissary
spec:
  port: 8443
  protocol: HTTPS
  securityModel: SECURE
  hostBinding:
    namespace:
      from: ALL
    selector:
      matchLabels:
        external-hosts: "true"
---
apiVersion: getambassador.io/v3alpha1
kind: Host
metadata:
  name: host-external
  namespace: emissary
  labels:
    external-hosts: "true"
spec:
  hostname: "server.example.com"  <<<<<<<<< Removing this line it will work.
  acmeProvider:
    authority: none
  tlsSecret:
    name: emissary-selfsigned-cert
    namespace: emissary
  selector:
    matchLabels:
      external-mapping: "true"
---
apiVersion: getambassador.io/v3alpha1
kind: Mapping
metadata:
  name: server
  namespace: emissary
  labels:
    external-mapping: "true"
spec:
  hostname: "server.example.com"  <<<<<<<<< This works after removing hostname from Host
  prefix: /
  service: server:3002
