我在以下位置有此terraform.tfvars
文件:
root
|_prod
|_eu-west-2
|_dev
|_terraform.tfvars
|_cognito
|_terragrunt.hcl
它具有这些值:
terragrunt = {
terraform {
extra_arguments "custom_vars" {
commands = [
"apply",
"plan",
"import",
"push",
"refresh"
]
# With the get_tfvars_dir() function, you can use relative paths!
arguments = [
"-var-file=terraform.tfvars"
]
}
}
}
reply_to_email_address = "[email protected]"
我在文档中找不到如何访问此文件。我已经尝试过get_env
:
include {
path = find_in_parent_folders()
}
terraform {
// double `//` before module are important!
source = "../../../../../terraform-modules//cognito"
}
inputs = {
name = "pvg-online-${local.env}"
reply_to_email_address = get_env("reply_to_email_address", "")
}
但是它被设置为默认的""
这实际上是一个非常常见的用例,terragrunt具有内置功能。
在您的terragrunt.hcl
中,包含如下所示的terraform{}
块:
terraform {
# Note that the double-slash (//) syntax is not needed for local relative paths
source = "../../../../../terraform-modules/cognito"
extra_arguments "common_var" {
commands = get_terraform_commands_that_need_vars()
arguments = ["-var-file=${get_terragrunt_dir()}/../terraform.tfvars"]
}
}
inputs = {
name = "pvg-online-${local.env}"
# Since reply_to_email_address is provided in the parent terraform.tfvars file,
# it is not needed as an input
}
请注意get_terraform_commands_that_need_vars()
的使用,因此可以避免列出所有参数以及get_terraform_commands_that_need_vars()
列出get_terragrunt_dir()
的目录。
