Terraform untuk masing-masing dengan daftar objek

Question

Saya memiliki variabel berikut di file variable.tf:

variable tenants {
  description = "Map of project names to configuration."
  type = list(object({
    name  = string
    dname = string
    desc  = string
    site  = list(string)
  }))
  default = [{
      name  = "Tenant-1",
      dname = "Tenant-1",
      desc  = "Test Tenant 1",
      site  = ["site1", "site2"]
    },
    {
      name  = "Tenant-2",
      dname = "Tenant-2",
      desc  = "Test Tenant 2",
      site  = ["site1"]
    }]
}

Di file main.tf saya, saya ingin mengulang daftar ini. Saya memiliki kode berikut di file main.tf:

resource "mso_tenant" "restenant" {
  for_each = {for i, v in var.tenants:  i => v}
    name         = each.value.name
    display_name = each.value.dname
    description  = each.value.desc
    site_associations {
      site_id =  each.value.site
  }
}

Jadi hasil akhirnya adalah 2 penyewa dibuat dengan atribut seperti yang ditentukan dalam file variabel. Jadi tenant1 akan memiliki 2 site_associations dan tenant2 akan memiliki 1 pengaitan setelah dibuat.

Hasilnya harus:

name         = "Tenant-1"
display_name = "Tenant-1"
description  = "Test Tenant 1"
site_associations {
  site_id = site1
  site_id = site2
}

dan

name         = "Tenant-2"
display_name = "Tenant-2"
description  = "Test Tenant 2"
site_associations {
   site_id = site1
}

Saya mencoba yang berikut ini:

resource "mso_tenant" "restenant" {
  for_each = {for i, v in var.tenants:  i => v}
    name         = each.value.name
    display_name = each.value.dname
    description  = each.value.desc
    site_associations {
      site_id =  each.value.site
  }
}

Ini berfungsi untuk name, dnamedan desctetapi tidak mengulangi variabel situs (yang merupakan daftar). Ini menghasilkan pesan kesalahan:

each.value.site adalah daftar string dengan 1 elemen Nilai tidak sesuai untuk atribut "site_id": string diperlukan.

Mencoba memecahkan sebagai berikut:

resource "mso_tenant" "restenant" {
  for_each = {for i, v in var.tenants:  i => v}
    
    name         = each.value.name
    display_name = each.value.dname
    description  = each.value.desc
    site_associations {
      site_id = [for site in each.value.site: site]
  }
}

tapi ini juga memberi:

each.value.site adalah daftar string dengan 2 elemen Nilai tidak sesuai untuk atribut "site_id": string diperlukan.

Answer 1

Apa yang Anda cari adalah blok dinamis: https://www.terraform.io/docs/configuration/expressions.html#dynamic-blocks

Asli:

site_associations {
    site_id =  each.value.site
}

Dinamis:

dynamic "site_associations"{
    for_each = each.value.site
    content {
        site_id = site_associations.value
    }
}

The dynamicblok memungkinkan Anda untuk membuat yang lain for_eachloop atas each.value.site.

Catatan: nilai di dalam blok dinamis direferensikan menggunakan nama blok site_associations.value

Seluruh main.tf:

variable tenants {
  description = "Map of project names to configuration."
  type = list(object({
    name  = string
    dname = string
    desc  = string
    site  = list(string)
  }))
  default = [{
      name  = "Tenant-1",
      dname = "Tenant-1",
      desc  = "Test Tenant 1",
      site  = ["site1", "site2"]
    },
    {
      name  = "Tenant-2",
      dname = "Tenant-2",
      desc  = "Test Tenant 2",
      site  = ["site1"]
    }]
}

resource "mso_tenant" "restenant" {
  for_each = {for i, v in var.tenants:  i => v}
    name         = each.value.name
    display_name = each.value.dname
    description  = each.value.desc
    dynamic "site_associations"{
    for_each = each.value.site
    content {
      site_id = site_associations.value
    }
    }

}
