# consul
|
||
|
|
|
||
|
|
Stores the state in the [Consul](https://www.consul.io/) KV store at a given path.
|
||
|
|
|
||
|
|
This backend supports [state locking](/language/state/locking).
|
||
|
|
|
||
|
|
## Example Configuration
|
||
|
|
|
||
|
|
```hcl
|
||
|
|
terraform {
|
||
|
|
backend "consul" {
|
||
|
|
address = "consul.example.com"
|
||
|
|
scheme = "https"
|
||
|
|
path = "full/path"
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
Note that for the access credentials we recommend using a
|
||
|
|
[partial configuration](/language/settings/backends/configuration#partial-configuration).
|
||
|
|
|
||
|
|
## Data Source Configuration
|
||
|
|
|
||
|
|
```hcl
|
||
|
|
data "terraform_remote_state" "foo" {
|
||
|
|
backend = "consul"
|
||
|
|
config = {
|
||
|
|
path = "full/path"
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## Configuration variables
|
||
|
|
|
||
|
|
The following configuration options / environment variables are supported:
|
||
|
|
|
||
|
|
- `path` - (Required) Path in the Consul KV store
|
||
|
|
- `access_token` / `CONSUL_HTTP_TOKEN` - (Required) Access token
|
||
|
|
- `address` / `CONSUL_HTTP_ADDR` - (Optional) DNS name and port of your Consul endpoint specified in the
|
||
|
|
format `dnsname:port`. Defaults to the local agent HTTP listener.
|
||
|
|
- `scheme` - (Optional) Specifies what protocol to use when talking to the given
|
||
|
|
`address`, either `http` or `https`. SSL support can also be triggered
|
||
|
|
by setting then environment variable `CONSUL_HTTP_SSL` to `true`.
|
||
|
|
- `datacenter` - (Optional) The datacenter to use. Defaults to that of the agent.

- `gzip` - (Optional) `true` to compress the state data using gzip, or `false` (the default) to leave it uncompressed.
|
||
|
|
- `lock` - (Optional) `false` to disable locking. This defaults to true, but will require session permissions with Consul and at least kv write permissions on `$path/.lock` to perform locking.
|
||
|
|
- `ca_file` / `CONSUL_CACERT` - (Optional) A path to a PEM-encoded certificate authority used to verify the remote agent's certificate.
|
||
|
|
