Terraform Output 通過 Jenkins

Question

我無法在 terraform my-vpc output 中找到vpc_id和public_su.net.0 。

每次我發出以下命令時：

ansible-playbook playbook1.yml -e "vpc_id=$(terraform output my-vpc.vpc_id) vpc_subnet_id=$(terraform output my-vpc.public_subnets.0)" -vvv

但它打印 terraform output my-vpc

-bash-4.2$ terraform output my-vpc

我正在嘗試：不同的命名和路徑。 Jenkins 用戶權限。 output 的目的地。

Answer 1

輸出應該是人類可讀的：

terraform output命令默認以人類可讀的格式顯示，可以隨時間變化以提高清晰度。

這意味着使用通常的 terraform 語法獲取值並不容易，您需要使用像jq [1] 這樣的工具。 所以在你的例子中，那必須是這樣的：

VPC_ID=$(terraform output -json my-vpc | jq -r '.vpc_id')
VPC_SUBNET_ID=$(terraform output -json my-vpc | jq -r '.public_subnets[0]')

其次是：

ansible-playbook playbook1.yml -e vpc_id=$VPC_ID -e vpc_subnet_id=$VPC_SUBNET_ID -vvv

我的 Ansible 技能有點生疏，可能有更好的方法，但這應該可以幫助您入門。

Answer 2

感謝支持我的學院，我們找到了解決方案：jq；）

ansible-playbook playbook1.yml -e "vpc_id=$(terraform output -json my-vpc|jq -r .vpc_id) vpc_subnet_id=$(terraform output -json my-vpc|jq -r .public_subnets[0])" -vvv
