# consul\_prepared\_query
Allows Terraform to manage a Consul prepared query.
Managing prepared queries is done using Consul's REST API. This resource is
useful to provide a consistent and declarative way of managing prepared
queries in your Consul cluster using Terraform.
## Example Usage
```
resource "consul_prepared_query" "service-near-self" {
datacenter = "nyc1"
token = "abcd"
stored_token = "wxyz"
name = ""
only_passing = true
near = "_agent"
template {
type = "name_prefix_match"
regexp = "^(.*)-near-self$"
}
service = "$${match(1)}"
failover {
nearest_n = 3
datacenters = ["dc2", "dc3", "dc4"]
}
dns {
ttl = "5m"
}
}
```
## Argument Reference
The following arguments are supported:
* `datacenter` - (Optional) The datacenter to use. This overrides the
datacenter in the provider setup and the agent's default datacenter.
* `token` - (Optional) The ACL token to use when saving the prepared query.
This overrides the token that the agent provides by default.
* `stored_token` - (Optional) The ACL token to store with the prepared
query. This token will be used by default whenever the query is executed.
* `name` - (Required) The name of the prepared query. Used to identify
the prepared query during requests. Can be specified as an empty string
to configure the query as a catch-all.
* `service` - (Required) The name of the service to query.
* `only_passing` - (Optional) When `true`, the prepared query will only
return nodes with passing health checks in the result.
* `near` - (Optional) Allows specifying the name of a node to sort results
near using Consul's distance sorting and network coordinates. The magic
`_agent` value can be used to always sort nearest the node servicing the
request.
* `failover` - (Optional) Options for controlling behavior when no healthy
nodes are available in the local DC.
* `nearest_n` - (Optional) Return results from this many datacenters,
sorted in ascending order of estimated RTT.
* `datacenters` - (Optional) Remote datacenters to return results from.
* `dns` - (Optional) Settings for controlling the DNS response details.
* `ttl` - (Optional) The TTL to send when returning DNS results.
* `template` - (Optional) Query templating options. This is used to make a
single prepared query respond to many different requests.
* `type` - (Required) The type of template matching to perform. Currently
only `name_prefix_match` is supported.
* `regexp` - (Required) The regular expression to match with. When using
`name_prefix_match`, this regex is applied against the query name.
## Attributes Reference
The following attributes are exported:
* `id` - The ID of the prepared query, generated by Consul.
