To create an image from a disk snapshot:

Management console

CLI

Terraform

API

In the management console, select the folder where you want to create an image.
Select Compute Cloud.
In the left-hand panel, select Snapshots.
In the line with the snapshot, click and select Create image.
Enter the image name. The naming requirements are as follows:
- The name must be from 3 to 63 characters long.
- It may contain lowercase Latin letters, numbers, and hyphens.
- The first character must be a letter and the last character cannot be a hyphen.
If required, provide a text description for the image.
To create an optimized image, enable Optimize for deployment.
Click Create.

If you do not have the Yandex Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

See the description of the CLI command to create an image:
```
yc compute image create --help
```

Get a list of snapshots in the default folder:

yc compute snapshot list

Result:

+----------------------+-----------------+----------------------+--------+----------------------------+
|          ID          |       NAME      |     PRODUCT IDS      | STATUS |        DESCRIPTION         |
+----------------------+-----------------+----------------------+--------+----------------------------+
| fd8rlt1u2rf0l******* | first-snapshot  | f2ecl5vhsftd******** | READY  | my first snapshot via CLI  |
| fhmolt1u2rf0******** | second-snapshot | f2eclmol5lps******** | READY  | my second snapshot via CLI |
+----------------------+-----------------+----------------------+--------+----------------------------+

Select ID or NAME of the snapshot you need.

Create an image in the default folder:

yc compute image create \
  --name first-image \
  --source-snapshot-name first-snapshot \
  --description "my first image via yc"

This command will create an image named first-image and described as my first image via yc from first-snapshot.

To create an optimized image, use the --pooled flag:

yc compute image create \
  --name first-image \
  --source-snapshot-name first-snapshot \
  --description "my first image via yc" \
  --pooled

If you don't have Terraform, install it and configure the Yandex Cloud provider.

Describe the parameters of the yandex_compute_image resource in the configuration file.

Here is an example of the configuration file structure:
```
resource "yandex_compute_image" "image-1" {
  name            = "<image_name>"
  source_snapshot = "<snapshot_ID>"
}
```
For more information about the resources you can create with Terraform, see the provider documentation.
Make sure the configuration files are correct.
1. In the command line, go to the folder where you created the configuration file.
2. Run a check using this command:
```
terraform plan
```
If the configuration is described correctly, the terminal will display a list of created resources and their parameters. If the configuration contains any errors, Terraform will point them out.
Deploy cloud resources.
1. Run this command:
```
terraform apply
```
2. Confirm that you want to create the resources.
All the resources you need will then be created in the specified folder. You can check the new resources and their settings using the management console.

Get the list of snapshots using the list REST API method for the Snapshot resource or the SnapshotService/List gRPC API call.
Create an image using the create REST API method for the Image resource or the ImageService/Create gRPC API call. Specify the snapshot ID in your request.

Once created, the image will get the CREATING status. Wait until its status changes to READY before using it.
