Consuming Private Cloud Hostnames

Prerequisites

• Your cluster needs to run Space Agent 2.17.0 or later.
• You need Local Agent 2.17.0 or later.
• You need macOS 15 or above with the Network Extension enabled in the Codezero desktop app.

1. Edit the ConfigMap domain-forwarding in the codezero namespace:

kubectl edit configmap domain-forwarding -n codezero

2. Set the data.domains value to the list of domains that you want to be able to consume, e.g.:

apiVersion: v1
data:
  domains: |
    - amazonaws.com
kind: ConfigMap
[…]

3. Consume the domains, e.g.:

echo "amazonaws.com" | czctl consume apply

4. Access the domains or any of its subdomains, e.g.:

$KAFKA_HOME/bin/kafka-broker-api-versions.sh --bootstrap-server b-1.democluster2.euesoh.c6.kafka.us-east-2.amazonaws.com:9096 --version

Versions prior to 2.17.0

If you are running version 2.16.1 or below, you can use the following steps if you want to consume a private cloud hostname that is accessible to your cluster. This approach does not support subdomains.

1. For each fully qualified hostname create a Kubernetes secret in the codezero namespace. The secret name must match the hostname of the external resource.

apiVersion: v1
kind: Secret
metadata:
  name: b-1.democluster2.euesoh.c6.kafka.us-east-2.amazonaws.com
  namespace: codezero
  annotations:
    codezero.io/credentials-infusion-type: none
    codezero.io/credentials-infusion-port: "9096"
type: Opaque

2. Consume b-1.democluster2.euesoh.c6.kafka.us-east-2.amazonaws.com service via the Codezero desktop app or czctl

echo "b-1.democluster2.euesoh.c6.kafka.us-east-2.amazonaws.com" | czctl consume apply
