Pass list to helm using terraform helm_release provider

问题

Ive看到了这个和另一个类似的问题，但无法让它工作。https://stackoverflow.com/questions/71754003/using-terraforms-helm-release-how-do-i-set-array-or-list-values

我的列表来自一个JSON文件，其中包含一组允许的群组

  1.   app_groups = jsondecode(file("../../work/resources/gke/params/access_auths.json")).accessgroups[var.project][0].app_group
  2. }
  3. output "app_groups" {
  4.     value = local.app_groups
  5. }

结果 -

  1.   "bigquery-team",
  2.   "devops-team",
  3. ]

main.tf -

  1.   name         = "oauth2proxy"
  2.   chart        = "../charts/oauth2proxy"
  3.   namespace    = kubernetes_namespace.oauth2proxy.metadata.0.name
  4.   set {
  5.     name  = "app_groups[0]"
  6.     value = "${local.app_groups}"
  7.   }
  8.   values = [
  9.     templatefile("../charts/oauth2proxy/oauth2proxy_values.yaml", {
  10.       projectID     = var.project
  11.       clusterName   = var.clusterName
  12.     })
  13.   ]
  14. }

在helm deployment.yml中，它需要在启动容器时进入-args -

  1.         - --allowed-group="{{ $v }}"
  2.       {{ end }}

但我得到了错误：

  1.  on main.tf line 129, in resource "helm_release" "oauth2proxy":
  2.  129:     value = "${local.app_groups}"
  3.  ────────────────
  4.  │ local.app_groups is tuple with 2 elements
  5.  │ Inappropriate value for attribute "value": string required.

问题是，它是一个元组，我希望它仍然是元组，但我不知道如何告诉terraform或helm它应该是一个元组。

我尝试过各种不同的"set"和"dynamic set"，但都没有取得进展。

Ive seen this and another question similar, but cannot get it to work https://stackoverflow.com/questions/71754003/using-terraforms-helm-release-how-do-i-set-array-or-list-values

My list is coming from a json file which is a list of allowed groups

  1. locals {
  2.   app_groups = jsondecode(file("../../work/resources/gke/params/access_auths.json")).accessgroups[var.project][0].app_group
  3. }
  4. output "app_groups" {
  5.     value = local.app_groups
  6. }

Gives -

  1. app_groups = [
  2.   "bigquery-team",
  3.   "devops-team",
  4. ]

main.tf -

  1. resource "helm_release" "oauth2proxy" {
  2.   name         = "oauth2proxy"
  3.   chart        = "../charts/oauth2proxy"
  4.   namespace    = kubernetes_namespace.oauth2proxy.metadata.0.name
  5.   set {
  6.     name  = "app_groups[0]"
  7.     value = "${local.app_groups}"
  8.   }
  9.   values = [
  10.     templatefile("../charts/oauth2proxy/oauth2proxy_values.yaml", {
  11.       projectID     = var.project
  12.       clusterName   = var.clusterName
  13.     })
  14.   ]
  15. }

In helm deployment.yml it needs to go into the -args when starting the container -

  1.       {{  range $v := .app_groups }}
  2.         - --allowed-group="{{ $v }}"
  3.       {{ end }}

But i get

  1. Error: Incorrect attribute value type
  2.  on main.tf line 129, in resource "helm_release" "oauth2proxy":
  3.  129:     value = "${local.app_groups}"
  4.  ────────────────
  5.  │ local.app_groups is tuple with 2 elements
  6.  │ Inappropriate value for attribute "value": string required.

The thing is, it is a tuple, and want it to be a tuple, and i cant see how to tell terraform or helm that its supposed to be a tuple.

Ive tried various different "set" and "dynamic set" but not got anywhere with it.

得分: 5

value 期望是一个字符串。在 Helm 中，你可以使用{a, b, c}语法来提供一个数组。要构建这个语法，你可以使用 join()：

  1. set {
  2.   name  = "app_groups"
  3.   value = "{${join(",", local.app_groups)}}"
  4. }

这应该可以解决问题，以{bigquery-team, devops-team}的形式提供 app_groups 作为数组。我不确定是否需要引号，但这可以很容易地添加。

英文:

value expects a string. In Helm you can provide an array using {a, b, c} syntax. To build this syntax you can use join():

  1. set {
  2.   name  = "app_groups"
  3.   value = "{${join(",", local.app_groups)}}"
  4. }

This should do the trick and provide app_groups as an array in the form of {bigquery-team, devops-team}. I am not sure if quoting is needed, but this could be added easily.
