Terraform Outputs - extract the value of output variables from the state file

[vincentclee]

Is there a way to list outputs from the state file and use the values downstream?

Example

main.tf

...
output "instance_ips" {
  value = aws_instance.web.*.public_ip
}

output "lb_address" {
  value = aws_alb.web.public_dns
}

output "password" {
  sensitive = true
  value = var.secret_password
}

Jenkinsfile

Jenkinsfile.init(this)
def validate = new TerraformValidateStage()
def deployUat = new TerraformEnvironmentStage("uat")
validate.then(deployUat).build()

// proposed
def outputs = deployUat.getOutputs()
echo outputs
echo outputs["lb_address"]

$ terraform output
instance_ips = [
  "54.43.114.12",
  "52.122.13.4",
  "52.4.116.53"
]
lb_address = "my-app-alb-1657023003.us-east-1.elb.amazonaws.com"
password = <sensitive>
