# etcdv3
|
|
|
|
**Kind: Standard (with locking)**
|
|
|
|
Stores the state in the [etcd](https://coreos.com/etcd/) KV store with a given prefix.
|
|
|
|
This backend supports [state locking](/docs/language/state/locking.html).
|
|
|
|
## Example Configuration
|
|
|
|
```hcl
|
|
terraform {
|
|
backend "etcdv3" {
|
|
endpoints = ["etcd-1:2379", "etcd-2:2379", "etcd-3:2379"]
|
|
lock = true
|
|
prefix = "terraform-state/"
|
|
}
|
|
}
|
|
```
|
|
|
|
Note that for the access credentials we recommend using a
|
|
[partial configuration](/docs/language/settings/backends/configuration.html#partial-configuration).
|
|
|
|
## Data Source Configuration
|
|
|
|
```hcl
|
|
data "terraform_remote_state" "foo" {
|
|
backend = "etcdv3"
|
|
config = {
|
|
endpoints = ["etcd-1:2379", "etcd-2:2379", "etcd-3:2379"]
|
|
lock = true
|
|
prefix = "terraform-state/"
|
|
}
|
|
}
|
|
```
|
|
|
|
