I have an existing resource group on Azure with a VM running on it and have been playing around with Terraform to try and import the resource to my state file.
I have set up a skeleton file, and as far as my understanding is once I import TF should populate this with the values on my resource group in Azure
resource "azurerm" "example" {
# ...instance configuration...
name = "MyResourceGroup"
}
Command I am running from CLI:
terraform import azurerm_resource_group.MyResourceGroup/subscriptions/MySubscriptionNumber/resourceGroups/MyResourceGroup
Message from Terraform:
The import command expects two arguments.
Usage: terraform import [options] ADDR ID
Import existing infrastructure into your Terraform state.
This will find and import the specified resource into your Terraform
state, allowing existing infrastructure to come under Terraform
management without having to be initially created by Terraform.
The ADDR specified is the address to import the resource to. Please
see the documentation online for resource addresses. The ID is a
resource-specific ID to identify that resource being imported. Please
reference the documentation for the resource type you're importing to
determine the ID syntax to use. It typically matches directly to the ID
that the provider uses.
The current implementation of Terraform import can only import resources
into the state. It does not generate configuration. A future version of
Terraform will also generate configuration.
Because of this, prior to running terraform import it is necessary to write
a resource configuration block for the resource manually, to which the
imported object will be attached.
This command will not modify your infrastructure, but it will make
network requests to inspect parts of your infrastructure relevant to
the resource being imported.
Options:
-backup=path Path to backup the existing state file before
modifying. Defaults to the "-state-out" path with
".backup" extension. Set to "-" to disable backup.
-config=path Path to a directory of Terraform configuration files
to use to configure the provider. Defaults to pwd.
If no config files are present, they must be provided
via the input prompts or env vars.
-allow-missing-config Allow import when no resource configuration block exists.
-input=true Ask for input for variables if not directly set.
-lock=true Lock the state file when locking is supported.
-lock-timeout=0s Duration to retry a state lock.
-no-color If specified, output won't contain any color.
-provider=provider Specific provider to use for import. This is used for
specifying aliases, such as "aws.eu". Defaults to the
normal provider prefix of the resource being imported.
-state=PATH Path to the source state file. Defaults to the configured
backend, or "terraform.tfstate"
-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.
-var 'foo=bar' Set a variable in the Terraform configuration. This
flag can be set multiple times. This is only useful
with the "-config" flag.
-var-file=foo Set variables in the Terraform configuration from
a file. If "terraform.tfvars" or any ".auto.tfvars"
files are present, they will be automatically loaded.
Any help much appreciated
It looks like you need to fix your script file first - azurerm isn't a valid resource name, did you mean:
resource "azurerm_resource_group" "example" {
# ...instance configuration...
name = "MyResourceGroup"
}
As seen in the output, import is expecting two parameters, ADDR and ID - you're only passing (what I assume is) the ID. You also need to tell terraform which resource in your script it maps to:
terraform import azurerm_resource_group.example \
/subscriptions/MySubscriptionNumber/resourceGroups/MyResourceGroup
