# aws\_instance
|
||||
|
||||
Use this data source to get the ID of an EC2 Instance for use in other
|
||||
resources.
|
||||
|
||||
## Example Usage
|
||||
|
||||
```
|
||||
data "aws_instance" "foo" {
|
||||
instance_id = "i-instanceid"
|
||||
filter {
|
||||
name = "image-id"
|
||||
values = ["ami-xxxxxxxx"]
|
||||
}
|
||||
filter {
|
||||
name = "tag:Name"
|
||||
values = ["instance-name-tag"]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Argument Reference
|
||||
|
||||
* `instance_id` - (Optional) Specify the exact Instance ID to populate the data source with.
|
||||
|
||||
* `filter` - (Optional) One or more name/value pairs to filter off of. There are
|
||||
several valid keys, for a full reference, check out
|
||||
[describe-instances in the AWS CLI reference][1].
|
||||
|
||||
~> **NOTE:** At least one of `filter` or `instance_id` must be specified.
|
||||
|
||||
~> **NOTE:** If more or less than a single match is returned by the search,
|
||||
Terraform will fail. Ensure that your search is specific enough to return
|
||||
a single Instance ID only.
|
||||
|
||||
## Attributes Reference
|
||||
