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.
