docs Command: remote config docs-commands-remote-config The `terraform remote config` command is used to configure Terraform to make use of remote state storage, change remote storage configuration, or to disable it.

Command: remote config

The terraform remote config command is used to configure use of remote state storage. By default, Terraform persists its state only to a local disk. When remote state storage is enabled, Terraform will automatically fetch the latest state from the remote server when necessary and if any updates are made, the newest state is persisted back to the remote server. In this mode, users do not need to durably store the state using version control or shared storaged.

Usage

Usage: terraform remote config [options]

The remote config command can be used to enable remote storage, change configuration or disable the use of remote storage. Terraform supports multiple types of storage backends, specified by using the -backend flag. By default, Atlas is assumed to be the storage backend. Each backend expects different, configuration arguments documented below.

When remote storage is enabled, an existing local state file can be migrated. By default, remote config will look for the "terraform.tfstate" file, but that can be specified by the -state flag. If no state file exists, a blank state will be configured.

When remote storage is disabled, the existing remote state is migrated to a local file. This defaults to the -state path during restore.

The following backends are supported:

  • Atlas - Stores the state in Atlas. Requires the -name and -access-token flag. The -address flag can optionally be provided.

  • Consul - Stores the state in the KV store at a given path. Requires the path flag. The -address and -access-token flag can optionally be provided. Address is assumed to be the local agent if not provided.

  • HTTP - Stores the state using a simple REST client. State will be fetched via GET, updated via POST, and purged with DELETE. Requires the -address flag.

The command-line flags are all optional. The list of available flags are:

  • -address=url - URL of the remote storage server. Required for HTTP backend, optional for Atlas and Consul.

  • -access-token=token - Authentication token for state storage server. Required for Atlas backend, optional for Consul.

  • -backend=Atlas - Specifies the type of remote backend. Must be one of Atlas, Consul, or HTTP. Defaults to Atlas.

  • -backup=path - Path to backup the existing state file before modifying. Defaults to the "-state" path with ".backup" extension. Set to "-" to disable backup.

  • -disable - Disables remote state management and migrates the state to the -state path.

  • -name=name - Name of the state file in the state storage server. Required for Atlas backend.

  • -path=path - Path of the remote state in Consul. Required for the Consul backend.

  • -pull=true - Controls if the remote state is pulled before disabling. This defaults to true to ensure the latest state is cached before disabling.

  • -state=path - Path to read state. Defaults to "terraform.tfstate" unless remote state is enabled.
