Install Zeebe exporters

Camunda 8 Self-Managed Helm chart supports the addition of Zeebe exporters by using initContainer.

The following is an example to install Zeebe Hazelcast and Kafka exporters.

extraInitContainers:
  - name: init-exporters-hazelcast
    image: busybox:1.35
    command: ["/bin/sh", "-c"]
    args:
      [
        "wget --no-check-certificate https://repo1.maven.org/maven2/io/zeebe/hazelcast/zeebe-hazelcast-exporter/0.8.0-alpha1/zeebe-hazelcast-exporter-0.8.0-alpha1-jar-with-dependencies.jar -O /exporters/zeebe-hazelcast-exporter.jar; ls -al /exporters",
      ]
    volumeMounts:
      - name: exporters
        mountPath: /exporters/
  - name: init-exporters-kafka
    image: busybox:1.35
    command: ["/bin/sh", "-c"]
    args:
      [
        "wget --no-check-certificate https://github.com/zeebe-io/zeebe-kafka-exporter/releases/download/1.1.0/zeebe-kafka-exporter-1.1.0-uber.jar -O /exporters/zeebe-kafka-exporter.jar; ls -al /exporters",
      ]
    volumeMounts:
      - name: exporters
        mountPath: /exporters/
env:
  - name: ZEEBE_BROKER_EXPORTERS_HAZELCAST_JARPATH
    value: /exporters/zeebe-hazelcast-exporter.jar
  - name: ZEEBE_BROKER_EXPORTERS_HAZELCAST_CLASSNAME
    value: io.zeebe.hazelcast.exporter.HazelcastExporter
  - name: ZEEBE_HAZELCAST_REMOTE_ADDRESS
    value: "{{ .Release.Name }}-hazelcast"

This example is downloading the exporters' JAR from a URL and adding the JAR to the exporters directory, which will be scanned for JARs and added to the Zeebe broker classpath. Then, with environment variables, you can configure the exporter parameters.
