多个 EC2 实例匹配； 使用额外的约束来减少对单个 EC2 实例的匹配

Question

I am using the following script to query a particular instance. There will be only one running instance with the given name. It is possible that another instance with the same name may exists but in different instance state.

How do I filter instance on instance's state so it only retrieves instance that is running state?

data "aws_instance" "ec2" {
  filter {
    name   = "tag:Name"
    values = ["dev-us-west-2-myinstance"]
  } 
}

Currently I get the following error

multiple EC2 Instances matched; use additional constraints to reduce matches to a single EC2 Instance

Answer 1

The terraform documentation , links to the AWS documentation for the describe-instances filter.

That documentation indicates you should do the following:

data "aws_instance" "ec2" {
  filter {
    name   = "tag:Name"
    values = ["dev-us-west-2-myinstance"]
  } 

  filter {
    name   = "instance-state-name"
    values = ["running"]
  } 
}
