github.com/hugorut/terraform@v1.1.3/website/docs/language/settings/backends/swift.mdx (about) 1 --- 2 page_title: 'Backend Type: swift' 3 description: Terraform can store state remotely in Swift. 4 --- 5 6 # swift 7 8 Stores the state as an artifact in [Swift](http://docs.openstack.org/developer/swift/latest/). 9 10 This backend supports [state locking](/language/state/locking). 11 12 ~> 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`](/language/settings/backends/swift#archive_container) configuration. This allows for state recovery in the case of accidental deletions and human error. 13 14 ## Example Configuration 15 16 ```hcl 17 terraform { 18 backend "swift" { 19 container = "terraform-state" 20 archive_container = "terraform-state-archive" 21 } 22 } 23 ``` 24 25 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. 26 27 For the access credentials we recommend using a 28 [partial configuration](/language/settings/backends/configuration#partial-configuration). 29 30 ## Data Source Configuration 31 32 ```hcl 33 data "terraform_remote_state" "foo" { 34 backend = "swift" 35 config = { 36 container = "terraform_state" 37 archive_container = "terraform_state-archive" 38 } 39 } 40 ``` 41 42 ## Configuration variables 43 44 The following configuration options are supported: 45 46 * `auth_url` - (Optional) The Identity authentication URL.

If 56 omitted, the `OS_REGION_NAME` environment variable is used. 57 58 * `container` - (Required) The name of the container to create for storing 59 the Terraform state file. 60 61 * `state_name` - (Optional) The name of the state file in the container. 62 Defaults to `tfstate.tf`. 63 64 * `path` - (Optional) DEPRECATED: Use `container` instead. 65 The name of the container to create in order to store the state file. 66 67 * `user_name` - (Optional) The Username to login with. If omitted, the 68 `OS_USERNAME` environment variable is used. 69 70 * `user_id` - (Optional) The User ID to login with.

By specifying a token, you do not have to specify a username/password 99 combination, since the token was already created by a username/password out of 100 band of Terraform. If omitted, the `OS_TOKEN` or `OS_AUTH_TOKEN` environment 101 variables are used. 102 103 * `user_domain_name` - (Optional) The domain name where the user is located. If 104 omitted, the `OS_USER_DOMAIN_NAME` environment variable is checked. 105 106 * `user_domain_id` - (Optional) The domain ID where the user is located. If 107 omitted, the `OS_USER_DOMAIN_ID` environment variable is checked. 108 109 * `project_domain_name` - (Optional) The domain name where the project is 110 located. If omitted, the `OS_PROJECT_DOMAIN_NAME` environment variable is 111 checked. 112 113 * `project_domain_id` - (Optional) The domain ID where the project is located 114 If omitted, the `OS_PROJECT_DOMAIN_ID` environment variable is checked. 115 116 * `domain_id` - (Optional) The ID of the Domain to scope to (Identity v3). If 117 omitted, the following environment variables are checked (in this order): 118 `OS_USER_DOMAIN_ID`, `OS_PROJECT_DOMAIN_ID`, `OS_DOMAIN_ID`. 119 120 * `domain_name` - (Optional) The Name of the Domain to scope to (Identity v3). 121 If omitted, the following environment variables are checked (in this order): 122 `OS_USER_DOMAIN_NAME`, `OS_PROJECT_DOMAIN_NAME`, `OS_DOMAIN_NAME`, 123 `DEFAULT_DOMAIN`. 124 125 * `default_domain` - (Optional) The ID of the Domain to scope to if no other 126 domain is specified (Identity v3). If omitted, the environment variable 127 `OS_DEFAULT_DOMAIN` is checked or a default value of "default" will be 128 used. 129 130 * `insecure` - (Optional) Trust self-signed SSL certificates. If omitted, the 131 `OS_INSECURE` environment variable is used. 132 133 * `cacert_file` - (Optional) Specify a custom CA certificate when communicating 134 over SSL.

If omitted, the `OS_SWAUTH` environment 149 variable is used. You must also set `username` to the Swauth/Swift username 150 such as `username:project`. Set the `password` to the Swauth/Swift key. This feature supports v1.0 of the Swauth system. 151 Finally, set `auth_url` as the location of the Swift service. 152 153 * `disable_no_cache_header` - (Optional) If set to `true`, the HTTP 154 `Cache-Control: no-cache` header will not be added by default to all API requests. 155 If omitted this header is added to all API requests to force HTTP caches (if any) 156 to go upstream instead of serving cached responses. 157 158 * `allow_reauth` - (Optional) If set to `true`, OpenStack authorization will be 159 perfomed automatically, if the initial auth token get expired. This is useful, 160 when the token TTL is low or the overall Terraform provider execution time 161 expected to be greater than the initial token TTL. 162 163 * `archive_container` - (Optional) The container to create to store archived copies 164 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`. 165 166 * `archive_path` - (Optional) DEPRECATED: Use `archive_container` instead. 167 The path to store archived copied of `terraform.tfstate`.

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. 172 ~> **NOTE:** Since Terraform is inherently stateful - we'd strongly recommend against auto-expiring Statefiles.
