将 Zip / 二进制文件添加到 configmap

Question

由于文件数量超过了 1mb 的限制，我正在尝试将一个 zip 文件添加到我们的配置映射中。我用 helm 部署了我们的图表，并正在研究 binaryData 但无法使其正常工作。我想看看是否有人对我如何将它与 helm 集成有任何建议，所以当工作完成时，它会删除配置映射

这是我的配置图：

apiVersion: v1
kind: ConfigMap
metadata:
  name: {{ template "db-migration.fullname" . }}
  labels:
    app: {{ template "db-migration.name" . }}
    chart: {{ template "db-migration.chart" . }}
    draft: {{ .Values.draft | default "draft-app" }}
    release: {{ .Release.Name }}
    heritage: {{ .Release.Service }}
binaryData:
  {{ .Files.Get "migrations.zip" | b64enc }}
immutable: true

---

apiVersion: v1
kind: ConfigMap
metadata:
  name: {{ template "db-migration.fullname" . }}-test
  labels:
    app: {{ template "db-migration.name" . }}
    chart: {{ template "db-migration.chart" . }}
    draft: {{ .Values.draft | default "draft-app" }}
    release: {{ .Release.Name }}
    heritage: {{ .Release.Service }}
binaryData:
  {{ .Files.Get "test.zip" | b64enc }}
immutable: true

这两个 zip 文件位于图表中，我有一个命令可以解压缩它们，然后运行之后进行迁移

binaryData exepcts a map 但是你传递了一个 string 给它。
调试模板时我们可以看到

Error: INSTALLATION FAILED: unable to build kubernetes objects from release manifest: error validating "": error validating data: ValidationError(ConfigMap.binaryData): invalid type for io.k8s.api.core.v1.ConfigMap.binaryData: got "string", expected "map"

解决这个问题的方法是在 {{ .Files.Get "test.zip" | b64enc }} 之前添加一个密钥。

apiVersion: v1
kind: ConfigMap
metadata:
  name: {{ template "db-migration.fullname" . }}
  labels:
    app: {{ template "db-migration.name" . }}
    chart: {{ template "db-migration.chart" . }}
    draft: {{ .Values.draft | default "draft-app" }}
    release: {{ .Release.Name }}
    heritage: {{ .Release.Service }}
binaryData:
  migrations: {{ .Files.Get "migrations.zip" | b64enc }}
immutable: true
