Terraform can store state remotely in Swift.
|
|
---
|
|
|
|
# swift
|
|
|
|
Stores the state as an artifact in [Swift](http://docs.openstack.org/developer/swift/latest/).
|
|
|
|
This backend supports [state locking](/docs/language/state/locking.html).
|
|
|
|
~> Warning! It is highly recommended that you enable [Object Versioning](https://docs.openstack.org/developer/swift/latest/overview_object_versioning.html) by setting the [`archive_container`](https://www.terraform.io/docs/language/settings/backends/swift.html#archive_container) configuration. This allows for state recovery in the case of accidental deletions and human error.
|
|
|
|
## Example Configuration
|
|
|
|
```hcl
|
|
terraform {
|
|
backend "swift" {
|
|
container = "terraform-state"
|
|
archive_container = "terraform-state-archive"
|
|
}
|
|
}
|
|
```
|
|
This will create a container called `terraform-state` and an object within that container called `tfstate.tf`. It will enable versioning using the `terraform-state-archive` container to contain the older version.
|
|
|
|
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 = "swift"
|
|
config = {
|
|
container = "terraform_state"
|
|
archive_container = "terraform_state-archive"
|
|
}
|
|
}
|
|
```
|
|
|
|
## Configuration variables

`OS_AUTH_URL` environment variable is used.
|
|
|
|
* `cloud` - (Optional; required if `auth_url` is not specified) An entry in a
|
|
`clouds.yaml` file. See the OpenStack `os-client-config`
|
|
[documentation](https://docs.openstack.org/os-client-config/latest/user/configuration.html)
|
|
for more information about `clouds.yaml` files. If omitted, the `OS_CLOUD`
|
|
environment variable is used.

|
|
the Terraform state file.
|
|
|
|
* `state_name` - (Optional) The name of the state file in the container.
|
|
Defaults to `tfstate.tf`.
|
|

|
|
application credential to authenticate with. Requires `user_id`, or

|
|
combination, since the token was already created by a username/password out of
|
|
band of Terraform. If omitted, the `OS_TOKEN` or `OS_AUTH_TOKEN` environment
|
|
variables are used.
|
|
|

|
|
`DEFAULT_DOMAIN`.
|
|
|
|
* `default_domain` - (Optional) The ID of the Domain to scope to if no other
|
|
domain is specified (Identity v3). If omitted, the environment variable

|
* `endpoint_type` - (Optional) Specify which type of endpoint to use from the
|
|
service catalog. It can be set using the OS_ENDPOINT_TYPE environment
|
|
variable. If not set, public endpoints is used.
|
|
|
|
* `swauth` - (Optional) Set to `true` to authenticate against Swauth, a
|
|
Swift-native authentication system. If omitted, the `OS_SWAUTH` environment
|
|
variable is used. You must also set `username` to the Swauth/Swift username
|
|
such as `username:project`. Set the `password` to the Swauth/Swift key. This feature supports v1.0 of the Swauth system.
|
|
Finally, set `auth_url` as the location of the Swift service.
|
|
|
|
* `disable_no_cache_header` - (Optional) If set to `true`, the HTTP
|
|
`Cache-Control: no-cache` header will not be added by default to all API requests.

|
|
to go upstream instead of serving cached responses.
|
|
|
|
* `allow_reauth` - (Optional) If set to `true`, OpenStack authorization will be
|
|
perfomed automatically, if the initial auth token get expired. This is useful,

|
|
expected to be greater than the initial token TTL.
|
|
|
|
* `archive_container` - (Optional) The container to create to store archived copies
|
|
of the Terraform state file. If specified, Swift [object versioning](https://docs.openstack.org/developer/swift/latest/overview_object_versioning.html) is enabled on the container created at `container`.
|
|
|
|
* `archive_path` - (Optional) DEPRECATED: Use `archive_container` instead.
|
|
The path to store archived copied of `terraform.tfstate`. If specified,
|
|
Swift [object versioning](https://docs.openstack.org/developer/swift/latest/overview_object_versioning.html) is enabled on the container created at `path`.
|
|
|
|
* `expire_after` - (Optional) How long should the `terraform.tfstate` created at `container`
|
|
be retained for? If specified, Swift [expiring object support](https://docs.openstack.org/developer/swift/latest/overview_expiring_objects.html) is enabled on the state. Supported durations: `m` - Minutes, `h` - Hours, `d` - Days.
|
|
~> **NOTE:** Since Terraform is inherently stateful - we'd strongly recommend against auto-expiring Statefiles.
