» consul_keys

The consul_keys resource writes sets of individual values into Consul. This is a powerful way to expose infrastructure details to clients.

This resource manages individual keys, and thus it can create, update and delete the keys explicitly given. However, it is not able to detect and remove additional keys that have been added by non-Terraform means. To manage all keys sharing a common prefix, and thus have Terraform remove errant keys not present in the configuration, consider using the consul_key_prefix resource instead.

» Example Usage

resource "consul_keys" "app" {
  datacenter = "nyc1"
  token      = "abcd"

  # Set the CNAME of our load balancer as a key
  key {
    path  = "service/app/elb_address"
    value = "${aws_elb.app.dns_name}"

» Argument Reference

The following arguments are supported:

  • datacenter - (Optional) The datacenter to use. This overrides the agent's default datacenter and the datacenter in the provider setup.

  • token - (Optional) The ACL token to use. This overrides the token that the agent provides by default.

  • key - (Required) Specifies a key in Consul to be written. Supported values documented below.

  • namespace - (Optional, Enterprise Only) The namespace to create the keys within.

The key block supports the following:

  • path - (Required) This is the path in Consul that should be written to.

  • value - (Required) The value to write to the given path.

  • flags - (Optional) An unsigned integer value to attach to the key (defaults to 0).

  • delete - (Optional) If true, then the key will be deleted when either its configuration block is removed from the configuration or the entire resource is destroyed. Otherwise, it will be left in Consul. Defaults to false.

» Deprecated key arguments

Prior to Terraform 0.7, this resource was used both to read and write the Consul key/value store. The read functionality has moved to the consul_keys data source, whose documentation can be found via the navigation.

The pre-0.7 interface for reading keys is still supported for backward compatibility, but will be removed in a future version of Terraform.

» Attributes Reference

The following attributes are exported:

  • datacenter - The datacenter the keys are being written to.
