Terraform 计划显示导入 GCE 持久磁盘后的差异

Question

我必须从快照恢复 GCE 永久磁盘。现在我想将新磁盘导入 terraform。

所以我做到了：

terragrunt import google_compute_region_disk.region_disk projects/my-project/regions/australia-southeast1/disks/ops-syd-jenkins-00

这有效，因为我可以更正远程状态文件中的快照 ID。因此，状态文件刷新良好。 然而，当我这样做时

terragrunt plan

，它会向我显示差异并想要删除我现有的磁盘。

Terraform will perform the following actions:

  # google_compute_region_disk.region_disk will be destroyed
  - resource "google_compute_region_disk" "region_disk" {
      - creation_timestamp        = "2022-03-15T18:11:16.301-07:00" -> null

        ] -> null

      - timeouts {}

    }

Plan: 1 to add, 0 to change, 1 to destroy.

不确定我做错了什么。谢谢。

Answer 1

我的错，这是一个糟糕的进口。需要运行以下命令才能导入：

terragrunt import google_compute_region_disk.region_disk["ops-syd-jenkins-00"] projects/my-project/regions/australia-southeast1/disks/ops-syd-jenkins-00

terraform 导入的一个好方法是有一个 diff 脚本，例如它将显示状态上真正发生的变化。 下面的示例脚本：

#!/usr/bin/env bash
#
# Get plan
terraform plan -out=tfplan > /dev/null 2>&1

# Convert plan to json
CHANGES=$(terraform show -json tfplan | jq '.resource_changes[].change')

# Diff before and after with newlines expanded
diff -u \
  <(echo "$CHANGES" | jq '.before' | sed 's/\\n/\//g') \
  <(echo "$CHANGES" | jq '.after' | sed 's/\\n/\//g')
