The `terraform import` command is used to
|
|
|
|
[import existing resources](/docs/import/index.html)
|
|
|
|
into Terraform.
|
|
|
|
|
|
|
|
## Usage
|
|
|
|
|
|
|
|
Usage: `terraform import [options] ADDRESS ID`
|
|
|
|
|
|
|
|
Import will find the existing resource from ID and import it into your Terraform
|
|
|
|
state at the given ADDRESS.
|
|
|
|
|
|
|
|
ADDRESS must be a valid [resource address](/docs/internals/resource-addressing.html).
|
|
|
|
Because any resource address is valid, the import command can import resources
|
2020-04-10 14:54:19 +02:00
|
|
|
into modules as well as directly into the root of your state.
|
2016-05-18 20:56:51 +02:00
|
|
|
|
|
|
|
ID is dependent on the resource type being imported. For example, for AWS
|
|
|
|
instances it is the instance ID (`i-abcd1234`) but for AWS Route53 zones
|
2016-10-09 18:29:38 +02:00
|
|
|
it is the zone ID (`Z12ABC4UGMOZ2N`). Please reference the provider documentation for details
|
2016-05-18 20:56:51 +02:00
|
|
|
on the ID format. If you're unsure, feel free to just try an ID. If the ID
|
|
|
|
is invalid, you'll just receive an error message.
|
|
|
|
|
2020-08-01 00:22:50 +02:00
|
|
|
~> Warning: Terraform expects that each remote object it is managing will be
|
|
|
|
bound to only one resource address, which is normally guaranteed by Terraform
|
|
|
|
itself having created all objects. If you import existing objects into Terraform,
|
|
|
|
be careful to import each remote object to only one Terraform resource address.
|
|
|
|
If you import the same object multiple times, Terraform may exhibit unwanted
|
|
|
|
behavior. For more information on this assumption, see
|
|
|
|
[the State section](/docs/state/).

|
|
The command-line flags are all optional. The list of available flags are:
|
|
|
|
|
|
|
|
* `-backup=path` - Path to backup the existing state file. Defaults to
|
|
|
|
the `-state-out` path with the ".backup" extension. Set to "-" to disable
|
|
|
|
backups.
|
|
|
|
|
2016-11-02 19:11:42 +01:00
|
|
|
* `-config=path` - Path to directory of Terraform configuration files that
|
|
|
|
configure the provider for import. This defaults to your working directory.
|
|
|
|
If this directory contains no Terraform configuration files, the provider
|
|
|
|
must be configured via manual input or environmental variables.
|
|
|
|
|
2016-05-18 20:56:51 +02:00
|
|
|
* `-input=true` - Whether to ask for input for provider configuration.
|
|
|
|
|
2017-04-04 19:48:59 +02:00
|
|
|
* `-lock=true` - Lock the state file when locking is supported.
|
2016-05-18 20:56:51 +02:00
|
|
|
|
2017-04-04 19:48:59 +02:00
|
|
|
* `-lock-timeout=0s` - Duration to retry a state lock.
|
|
|
|
|
|
|
|
* `-no-color` - If specified, output won't contain any color.
|
2016-05-18 20:56:51 +02:00
|
|
|
|
2019-03-06 15:25:36 +01:00
|
|
|
* `-parallelism=n` - Limit the number of concurrent operation as Terraform
|
|
|
|
[walks the graph](/docs/internals/graph.html#walking-the-graph). Defaults
|
|
|
|
to 10.
|
|
|
|
|
2019-09-20 16:02:42 +02:00
|
|
|
* `-provider=provider` - **Deprecated** Override the provider configuration to
|
|
|
|
use when importing the object. By default, Terraform uses the provider specified
|
|
|
|
in the configuration for the target resource, and that is the best behavior in most cases.
|

|
|
|
|
2017-08-09 20:01:45 +02:00
|
|
|
* `-state=path` - Path to the source state file to read from. Defaults to the
|
|
|
|
configured backend, or "terraform.tfstate".
|
2017-04-04 19:48:59 +02:00
|
|
|
|
2017-08-09 20:01:45 +02:00
|
|
|
* `-state-out=path` - Path to the destination state file to write to. If this
|
|
|
|
isn't specified the source state file will be used. This can be a new or
|
|
|
|
existing path.
|
2017-04-04 19:48:59 +02:00
|
|
|
|
2017-01-24 22:01:23 +01:00
|
|
|
* `-var 'foo=bar'` - Set a variable in the Terraform configuration. This flag
|
|
|
|
can be set multiple times. Variable values are interpreted as
|
|
|
|
[HCL](/docs/configuration/syntax.html#HCL), so list and map values can be
|
|
|
|
specified via this flag. This is only useful with the `-config` flag.
|
|
|
|
|
|
|
|
* `-var-file=foo` - Set variables in the Terraform configuration from
|
2017-06-22 03:22:07 +02:00
|
|
|
a [variable file](/docs/configuration/variables.html#variable-files). If
|
|
|
|
a `terraform.tfvars` or any `.auto.tfvars` files are present in the current
|
|
|
|
directory, they will be automatically loaded. `terraform.tfvars` is loaded
|
|
|
|
first and the `.auto.tfvars` files after in alphabetical order. Any files
|
|
|
|
specified by `-var-file` override any values set automatically from files in
|
|
|
|
the working directory. This flag can be used multiple times. This is only
|
|
|
|
useful with the `-config` flag.

backend: Validate remote backend Terraform version
When using the enhanced remote backend, a subset of all Terraform
operations are supported. Of these, only plan and apply can be executed
on the remote infrastructure (e.g. Terraform Cloud). Other operations
run locally and use the remote backend for state storage.
This causes problems when the local version of Terraform does not match
the configured version from the remote workspace. If the two versions
are incompatible, an `import` or `state mv` operation can cause the
remote workspace to be unusable until a manual fix is applied.
To prevent this from happening accidentally, this commit introduces a
check that the local Terraform version and the configured remote
workspace Terraform version are compatible. This check is skipped for
commands which do not write state, and can also be disabled by the use
of a new command-line flag, `-ignore-remote-version`.
Terraform version compatibility is defined as:
- For all releases before 0.14.0, local must exactly equal remote, as
two different versions cannot share state;
- 0.14.0 to 1.0.x are compatible, as we will not change the state
version number until at least Terraform 1.1.0;
- Versions after 1.1.0 must have the same major and minor versions, as
we will not change the state version number in a patch release.
If the two versions are incompatible, a diagnostic is displayed,
advising that the error can be suppressed with `-ignore-remote-version`.
When this flag is used, the diagnostic is still displayed, but as a
warning instead of an error.
Commands which will not write state can assert this fact by calling the
helper `meta.ignoreRemoteBackendVersionConflict`, which will disable the
checks. Those which can write state should instead call the helper
`meta.remoteBackendVersionCheck`, which will return diagnostics for
display.
In addition to these explicit paths for managing the version check, we
have an implicit check in the remote backend's state manager
initialization method. Both of the above helpers will disable this
check. This fallback is in place to ensure that future code paths which
access state cannot accidentally skip the remote version check.
2020-11-13 22:43:56 +01:00
|
|
|
* `-ignore-remote-version` - When using the enhanced remote backend with
|
|
|
|
Terraform Cloud, continue even if remote and local Terraform versions differ.
|
|
|
|
This may result in an unusable Terraform Cloud workspace, and should be used
|
|
|
|
with extreme caution.

## Provider Configuration
|
|
|
|
|
2016-11-02 19:11:42 +01:00
|
|
|
Terraform will attempt to load configuration files that configure the
|
|
|
|
provider being used for import. If no configuration files are present or
|
|
|
|
no configuration for that specific provider is present, Terraform will
|
|
|
|
prompt you for access credentials. You may also specify environmental variables
|
|
|
|
to configure the provider.
|
|
|
|
|
|
|
|
The only limitation Terraform has when reading the configuration files
|
|
|
|
is that the import provider configurations must not depend on non-variable
|
|
|
|
inputs. For example, a provider configuration cannot depend on a data
|
|
|
|
source.
|
|
|
|
|
|
|
|
As a working example, if you're importing AWS resources and you have a
|
|
|
|
configuration file with the contents below, then Terraform will configure
|
|
|
|
the AWS provider with this file.
|
|
|
|
|
2017-04-05 17:29:27 +02:00
|
|
|
```hcl
|
2016-11-02 19:11:42 +01:00
|
|
|
variable "access_key" {}
|
|
|
|
variable "secret_key" {}
|
|
|
|
|
|
|
|
provider "aws" {
|
|
|
|
access_key = "${var.access_key}"
|
|
|
|
secret_key = "${var.secret_key}"
|
|
|
|
}
|
|
|
|
```
