我是terragrunt的新手，试图弄清楚如何在模块之间传递变量。我在这里遵循terragrunt文档，但是没有运气，并且出现错误:

因此，我在模块文件夹下为本地的vpc, ec2, s3编写了地形模块，这些模块由应用程序(工作区)和配置/tfvars用于基于区域和环境的环境，如上图所示。
正如您在上面看到的，terragrunt将network -vpc放在组1中，将ec2-amz-lnx放在组2中。我已经确保我已经在VPC中声明了输出(如下所示)
Outputs:
SecurityGroupID = "sg-xxx"
private_subs = {
"private_subnet_a" = "subnet-xxx"
"private_subnet_b" = "subnet-xxx"
}
public_subs = "subnet-xxx"
vpc_id = "vpc-xxx"
在ec2-amz-lnx文件夹中，我创建了terragrunt。HCL文件:
include {
path = find_in_parent_folders()
expose = true
}
dependency "shared_infra" {
config_path = "../networks-vpc"
# mock_outputs = {
# public_subs = "subnet-xxx"
# }
}
dependencies {
paths = ["../networks-vpc"]
}
inputs = {
public_subs = dependency.shared_infra.outputs.public_subs
}
和在ec2-amz-lnx中，我像下面这样传递public_sub值:
module "ec2" {
source = "../../modules/ec2"
vpc_public_subnet_id = public_subs
instance_type_lx = var.instance_type_lx_value
security_group_ids = var.security_group_ids_value
ec2keypair_name = var.ec2keypair_name_value
instance_count = var.instance_count_value
}
我花了一些时间和terrgarunt一起挖掘。
对于错误"要么目标模块尚未应用，要么模块没有输出。如果这是预期的，设置skip_outp…">
这个短语的问题是:如果你有模块A和模块B并且模块B依赖于模块A，那么==>您必须部署模块B，然后才能部署模块A。否则terragrunt无法从模块A找到输出(变量)并将其传递给模块B，因此您无法同时部署模块A和模块B。你需要两个独立的步骤。哦. ."模拟outputs"不能解决问题。
这使得terragrunt现在有点没用了。
纯地形没有这样的问题。
