Using the helm_release provider, I want to attach a sidecar container to a helm release. Specifically, I want to attach the sqlproxy container to the keto release. Below is my initial attempt but it does not pass values for sqlproxy config. How to add a container with values to a helm release?

使用HELM_RELEASE提供程序，我希望将SideCar容器附加到HELM发行版。具体地说，我希望将SQLProxy容器附加到keto发行版。下面是我的初始尝试，但它没有传递SQLProxy配置的值。如何将带有值的容器添加到Helm版本中？

locals {
  db_username = "postgres"
  sql_port = "5432"
}

resource "helm_release" "keto" {
  name       = "ory"
  repository = "https://k8s.ory.sh/helm/charts"
  chart      = "keto"

  values = [
    <<EOT
    serviceAccount:
      create: false
      name: ${module.service_account.value.id}
    job:
      serviceAccount:
        create: false
        name: ${module.service_account.value.id}
    keto:
      config:
        dsn: postgres://${local.db_username}:${random_password.password.result}@pg-sqlproxy-gcloud-sqlproxy:${local.sql_port}/db
    deploy:
      extraContainers:
        name: gcloud-sqlproxy
        image: # what to place here? how to add extra values here?
    EOT
  ]
}

The documentation for keto showed it offers a deployment:extraContainers field where I can set the name and the image for a container; however, unsure how to pass the additional values needed for sqlproxy

keto的文档显示它提供了一个deployment：extraContainers字段，我可以在其中设置容器的名称和映像;但是，不确定如何传递sqlproxy所需的其他值

How any particular settings are used are fairly chart-specific, and there's not a generic recipe for things like adding sidecar containers.

如何使用任何特定的设置都是特定于图表的，并且没有添加侧车容器之类的通用方法。

In this particular chart, the extraContainers setting is used as

在这个特定的图表中，ExtraContainers设置用作

      containers:
        - name: {{ .Chart.Name }}
          # ... about another 100 lines of settings ...
        {{- if $extraContainers }}
          {{- tpl $extraContainers . | nindent 8 }}
        {{- end }}

That is, if extraContainers is set, it must be a string; it is run through the Helm tpl extension function to render Go text/template markup using the top-level Helm object; and the result is indented to the correct level in the Deployment spec.

也就是说，如果设置了ExtraContainers，则它必须是一个字符串；它通过Helm TPL扩展函数运行，以使用顶级Helm对象呈现GO文本/模板标记；并且结果缩进到部署规范中的正确级别。

In the YAML you show, you need to end the extraContainers: line with a |, creating a YAML block scalar (a multi-line string). Under that you need to put a complete YAML list of container specs. You can include template blocks there if you want to.

在你展示的YAML中，你需要用一个|，创建YAML块标量（多行字符串）。在它下面，你需要放置一个完整的容器规范的YAML列表。如果需要，可以在其中包含模板块。

deploy:
  extraContainers: |
    - name: gcloud-sqlproxy
      image: gcr.io/cloudsql-docker/gce-proxy
      env:
        - name: KETO_CONFIG_DSN
          value: {{ .Values.keto.config.dsn }}

Note that you've provided a couple of links to a separate Helm chart for the proxy. That intrinsically will create a separate Helm release and objects like Kubernetes Deployments for it; it cannot attach it as a sidecar to other Deployments, and you can't use any of that chart's settings in a sidecar-container configuration.

请注意，您已经为代理提供了两个指向单独Helm图表的链接。这本质上将为它创建一个单独的Helm发行版和诸如Kubernetes部署的对象；它不能将它作为侧车附加到其他部署，并且您不能在侧车-容器配置中使用该图表的任何设置。
