Helm范圍yaml模板kafka主題

我是 helm 新手，我正在嘗試使用 range 函式為 kafka 生成不同的主題，以使每個主題都沒有 yaml 檔案：

我有不同的主題（主題1，主題2，主題3，...），它們唯一的區別是主題和名稱的保留毫秒數，有些主題有3600000，其他540000，這是我的值檔案：

KafkaTopics:
  shortRetentionTopics:
    name:
    - topic1
    - topic2
    - topic3
    - topic4
    spec:
      config: 
        retention.ms: 540000
      topicName:
      - topic1logs
      - topic2logs
      - topic3logs
      - topic4logs
  longRetentionTopics:
    name:
    - topic34
    - topic35
    spec:
      config: 
        retention.ms: 3600000
      topicName:
      - topic34logs
      - topic34logs

我想在這個模板上設定名稱、topicName和retention.ms，從值檔案中執行一個for回圈：

apiVersion: kafka.strimzi.io/v1beta2
kind: KafkaTopic
metadata:
  labels:
    strimzi.io/cluster: kafka
  name: (here the name of the topic)
  namespace: default
spec:
  config:
    retention.ms: (here the retention of the topic)
  partitions: 12
  replicas: 1
  topicName: (here the topicName of the topic)

或者，如果您有任何建議來更改值檔案的結構，以便更輕松地將值決議為我感興趣的模板。

這是一個例子

$ cat values.yaml
KafkaTopics:
  shortRetentionTopics:
    name:
    - topic1
    - topic2
    - topic3
    - topic4
    spec:
      config:
        retention.ms: 540000
  longRetentionTopics:
    name:
    - topic34
    - topic35
    spec:
      config:
        retention.ms: 3600000

$ cat templates/topics.yml
{{- with .Values.KafkaTopics.shortRetentionTopics }}{{- range .name }}
---
apiVersion: kafka.strimzi.io/v1beta2
kind: KafkaTopic
metadata:
  labels:
    strimzi.io/cluster: kafka
  name: {{ $.Release.Name }}-{{ . }}
  namespace: default
spec:
{{- toYaml $.Values.KafkaTopics.shortRetentionTopics.spec | nindent 2 }}
  partitions: 12
  replicas: 1
  topicName: {{.}}logs
{{- end}}{{- end}}

對長期保留主題重復此操作，或使用單獨的模板檔案。

示例除錯輸出 -helm template topics ./topic-example --debug

最后我最終這樣做了：

{{- range $topics := .Values.kafkaTopicList }}
{{ $spec := default dict $topics.spec }}
{{ $config := default dict $spec.config }}
{{ $retention := default dict $config.retentionMs }}
---
apiVersion: kafka.strimzi.io/v1beta2
kind: KafkaTopic
metadata:
  labels:
    strimzi.io/cluster: kafka
  name: {{ $topics.name }}
  namespace: default
spec:
  config:
    retention.ms: {{ $retention | default "540000" }}
  partitions: 12
  replicas: 1
  topicName: {{ $topics.name | replace "-" "." }}
{{- end}}

值檔案：

kafkaTopicList:
  topic1:
    name: events-1
  topic2:
    name: events-2
  topic3:
    name: events-3
  topic4:
    name: events-4
  topic5:
    name: events-5
  topic6:
    name: events-6
  topic7:
    name: events-7
    spec:
      config: 
        retentionMs: 3600000
