我刚刚执行了 terraform plan，它报告了很多虚假的变化。它报告说它需要重新创建大量资源，因为一些 ""(空字符串)的属性不是 null。
例如它认为我改变了这条路线
route = [
- {
- cidr_block = "0.0.0.0/0"
- egress_only_gateway_id = ""
- gateway_id = "igw-xxxx"
- instance_id = ""
- ipv6_cidr_block = ""
- nat_gateway_id = ""
- network_interface_id = ""
- transit_gateway_id = ""
- vpc_peering_connection_id = ""
},
+ {
+ cidr_block = "0.0.0.0/0"
+ egress_only_gateway_id = null
+ gateway_id = "igw-xxxx"
+ instance_id = null
+ ipv6_cidr_block = null
+ nat_gateway_id = null
+ network_interface_id = null
+ transit_gateway_id = null
+ vpc_peering_connection_id = null
},
据我所知，没有实际变化(在 terraform 配置中)所以我怀疑 这一定是商店状态与 Terraform 如何计算“所需”状态之间存在差异。
这是什么原因造成的？这是 terraform 0.13.1 和 0.13.5 之间的变化吗？
最佳答案
我遇到了同样的问题。此回复确定了解决方法:https://discuss.hashicorp.com/t/terraform-wants-to-replace-many-resources-because-it-detects-that-null/17845/2
我不确定这个错误是何时或如何引入 AWS 提供商的，但在从 0.11.14 升级到 0.12.28 后它突然出现了。
如果您显式定义所有这些空值，Terraform 将不再将此视为更改。
route {
- cidr_block = "0.0.0.0/0"
- gateway_id = "igw-ID"
+ cidr_block = "0.0.0.0/0"
+ gateway_id = "igw-ID"
+ egress_only_gateway_id = ""
+ instance_id = ""
+ ipv6_cidr_block = ""
+ nat_gateway_id = ""
+ network_interface_id = ""
+ transit_gateway_id = ""
+ vpc_peering_connection_id = ""
将我的计划从销毁并重新创建所有路线更改为仅添加一条新路线(匿名值):
# aws_route_table.main-vpc-ID will be updated in-place
~ resource "aws_route_table" "main-vpc-ID" {
id = "rtb-ID"
owner_id = "accountid"
propagating_vgws = []
~ route = [
{
cidr_block = "0.0.0.0/0"
egress_only_gateway_id = ""
gateway_id = "igw-ID"
instance_id = ""
ipv6_cidr_block = ""
nat_gateway_id = ""
network_interface_id = ""
transit_gateway_id = ""
vpc_peering_connection_id = ""
},
+ {
+ cidr_block = "10.100.2.0/24"
