     6  # etcdv3
     7  
     8  Stores the state in the [etcd](https://etcd.io/) KV store with a given prefix.
     9  
    10  This backend supports [state locking](/language/state/locking).
    11  
    12  ## Example Configuration
    13  
    14  ```hcl
    15  terraform {
    16    backend "etcdv3" {
    17      endpoints = ["etcd-1:2379", "etcd-2:2379", "etcd-3:2379"]
    18      lock      = true
    19      prefix    = "terraform-state/"
    20    }
    21  }
    22  ```
    23  
    24  Note that for the access credentials we recommend using a
    25  [partial configuration](/language/settings/backends/configuration#partial-configuration).
    26  
    27  ## Data Source Configuration
    28  
    29  ```hcl
    30  data "terraform_remote_state" "foo" {
    31    backend = "etcdv3"
    32    config = {
    33      endpoints = ["etcd-1:2379", "etcd-2:2379", "etcd-3:2379"]
    34      lock      = true
    35      prefix    = "terraform-state/"
    36    }
    37  }
    38  ```
    39  
    40  ## Configuration variables
    41  
    42  The following configuration options / environment variables are supported:
    43  
    44  - `endpoints` - (Required) The list of 'etcd' endpoints which to connect to.
    45  - `username` / `ETCDV3_USERNAME` - (Optional) Username used to connect to the etcd cluster.
    46  - `password` / `ETCDV3_PASSWORD` - (Optional) Password used to connect to the etcd  cluster.
    47  - `prefix` - (Optional) An optional prefix to be added to keys when to storing state in etcd. Defaults to `""`.
    48  - `lock` - (Optional) Whether to lock state access. Defaults to `true`.
    49  - `cacert_path` - (Optional) The path to a PEM-encoded CA bundle with which to verify certificates of TLS-enabled etcd servers.
    50  - `cert_path` - (Optional) The path to a PEM-encoded certificate to provide to etcd for secure client identification.
    51  - `key_path` - (Optional) The path to a PEM-encoded key to provide to etcd for secure client identification.
    52  - `max_request_bytes` - (Optional) The max request size to send to etcd. This can be increased to enable storage of larger state. You must set the corresponding server-side flag [--max-request-bytes](https://etcd.io/docs/current/dev-guide/limit/#request-size-limit) as well and the value should be less than the client setting. Defaults to `2097152` (2.0 MiB). **Please Note:** Increasing etcd's request size limit may negatively impact overall latency.
