etcdv3 (deprecated)

Note: The etcdv3 backend is deprecated and will be removed in a future Terraform release.

Stores the state in the etcd KV store with a given prefix.

This backend supports state locking.

Example Configuration

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.

Data Source Configuration

data "terraform_remote_state" "foo" {  backend = "etcdv3"  config = {    endpoints = ["etcd-1:2379", "etcd-2:2379", "etcd-3:2379"]    lock      = true    prefix    = "terraform-state/"  }}

Configuration Variables

Warning: We recommend using environment variables to supply credentials and other sensitive data. If you use -backend-config or hardcode these values directly in your configuration, Terraform will include these values in both state and plan files. Refer to Credentials and Sensitive Data for details.

The following configuration options / environment variables are supported:

endpoints - (Required) The list of 'etcd' endpoints which to connect to.
username / ETCDV3_USERNAME - (Optional) Username used to connect to the etcd cluster.
password / ETCDV3_PASSWORD - (Optional) Password used to connect to the etcd cluster.
prefix - (Optional) An optional prefix to be added to keys when to storing state in etcd. Defaults to "".
lock - (Optional) Whether to lock state access. Defaults to true.
cacert_path - (Optional) The path to a PEM-encoded CA bundle with which to verify certificates of TLS-enabled etcd servers.
cert_path - (Optional) The path to a PEM-encoded certificate to provide to etcd for secure client identification.
key_path - (Optional) The path to a PEM-encoded key to provide to etcd for secure client identification.
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 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.
