Terraform将多个属性块合并为一个

Question

我正在尝试使用terraform在DataBricks工作空间中自动化和提供DataBricks集群。

我们有预定义的库，需要在集群创建时安装，我们确实有大约20个库

variable"libraries"{
default = ["pypi","jar"]
}
variable"pythonpackages"{
default = ["conda","pymongo"]
}
variable"jarpackages"{
default = ["etc1","etc1"]
}
variable"repositories"{
default = ["internal1","internal2"]
}
resource "databricks_cluster" "shared_autoscaling" {
cluster_name            = "Shared Autoscaling"
spark_version           = data.databricks_spark_version.latest_lts.id
node_type_id            = data.databricks_node_type.smallest.id
autotermination_minutes = 20
autoscale {
min_workers = 1
max_workers = 50
}
library { 
pypi  {
package = "dnspython"
}
}
library { 
pypi  {
package = "condo"
}
}
library { 
pypi  {
package = "kedro"
repo = "artifactory-url"
}
}

}

我正在尝试删除库属性的重复性。我尝试了在库属性内使用for_each，但它没有正确工作。

我想达到的目标

variable"libraries"{
default = ["pypi","jar"]
}
variable"pythonpackages"{
default = ["conda","pymongo"]
}
variable"jarpackages"{
default = ["etc1","etc1"]
}
variable"repositories"{
default = ["internal1","internal2"]
}
resource "databricks_cluster" "shared_autoscaling" {
cluster_name            = "Shared Autoscaling"
spark_version           = data.databricks_spark_version.latest_lts.id
node_type_id            = data.databricks_node_type.smallest.id
autotermination_minutes = 20
autoscale {
min_workers = 1
max_workers = 50
}
library { 
pypi  {
package = ["condo","pymongo","listofpackages"]
}
}

}

您可以使用动态块来重复嵌套块。

例如，要重复库块，可以这样写:

resource "databricks_cluster" "shared_autoscaling" {
cluster_name            = "Shared Autoscaling"
spark_version           = data.databricks_spark_version.latest_lts.id
node_type_id            = data.databricks_node_type.smallest.id
autotermination_minutes = 20
autoscale {
min_workers = 1
max_workers = 50
}

dynamic "library" {
for_each = ["condo","pymongo","listofpackages"]
content {
pypi {
package = library.value
}
}
}
}
