我想通过terraform设置GCP CloudSQL。我正在读这篇文章。 (https://www.terraform.io/docs/providers/google/r/sql_database_instance.html)
我用这样的代码执行“terraform plan”。
resource "google_sql_database_instance" "master" {
name = "terraform-master"
region = "asia-northeasteast1"
database_version = "MYSQL_5_6"
project = "test-141901"
settings {
tier = "db-f1-micro"
replication_type = "SYNCHRONOUS"
backup_configuration {
enabled = true
start_time = "17:00"
}
ip_configuration {
ipv4_enabled = true
}
database_flags {
name = "slow_query_log"
value = "on"
name = "character_set_server"
value = "utf8mb4"
}
}
}
但我无法设置 MULTIPLE database_flags
settings.0.database_flags.#: "1"
settings.0.database_flags.0.name: "character_set_server"
settings.0.database_flags.0.value: "utf8mb4"
如何使用多个database_flags设置CloudSQL?我无法理解该文件中的“子列表支持”。

您应该可以使用多个database_flags
块来执行此操作:
resource "google_sql_database_instance" "master" {
name = "terraform-master"
region = "us-central1"
database_version = "MYSQL_5_6"
project = "test-project"
settings {
tier = "db-f1-micro"
replication_type = "SYNCHRONOUS"
backup_configuration {
enabled = true
start_time = "17:00"
}
ip_configuration {
ipv4_enabled = true
}
database_flags {
name = "slow_query_log"
value = "on"
}
database_flags {
name = "character_set_server"
value = "utf8mb4"
}
}
}
以下是terraform plan
的输出,上面的tf:
+ google_sql_database_instance.master
database_version: "MYSQL_5_6"
ip_address.#: "<computed>"
name: "terraform-master"
project: "test-project"
region: "us-central1"
self_link: "<computed>"
settings.#: "1"
settings.0.backup_configuration.#: "1"
settings.0.backup_configuration.0.enabled: "true"
settings.0.backup_configuration.0.start_time: "17:00"
settings.0.database_flags.#: "2"
settings.0.database_flags.0.name: "slow_query_log"
settings.0.database_flags.0.value: "on"
settings.0.database_flags.1.name: "character_set_server"
settings.0.database_flags.1.value: "utf8mb4"
settings.0.ip_configuration.#: "1"
settings.0.ip_configuration.0.ipv4_enabled: "true"
settings.0.replication_type: "SYNCHRONOUS"
settings.0.tier: "db-f1-micro"
settings.0.version: "<computed>"

我想详细说明这个答案,因为我需要根据输入生成 database_flags
块。假设您有一个变量
variable "database-flags" {
type = "map"
default = {
character_set_server = "utf8mb4"
slow_query_log = "on"
}
}
使用terraform v0.12.X
可以写为
resource "google_sql_database_instance" "master" {
name = "terraform-master"
region = "us-central1"
database_version = "MYSQL_5_6"
project = "test-project"
settings {
tier = "db-f1-micro"
replication_type = "SYNCHRONOUS"
backup_configuration {
enabled = true
start_time = "17:00"
}
ip_configuration {
ipv4_enabled = true
}
dynamic "database_flags" {
iterator = flag
for_each = var.database-flags
content {
name = flag.key
value = flag.value
}
}
}
}
使用上述模式,您可以将代码的数据库创建部分用作模块,并让使用者决定应设置哪些标志
