A bucket label is a key-value pair used for logical bucket labeling.

Note

Yandex Cloud uses labels to logically identify resources. However, Object Storage supports compatibility with Amazon S3 API, that is why we use tags, a term native to AWS, in the AWS CLI commands and API parameters.

Adding or updating labels

Management console

Yandex Cloud CLI

AWS CLI

Terraform

API

In the management console, select Object Storage from the list of services and go to the bucket where you need to add or edit labels.
In the left-hand panel, select Settings.
Select the General tab.
Click Add label.
Enter a label in key: value format. To update an existing label, enter its key and a new value.
Press Enter.
Click Save.

Warning

Updating the bucket settings will completely overwrite the existing labels.

If you do not have the Yandex Cloud CLI installed yet, install and initialize it.

By default, the CLI uses the folder specified when creating the profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also set a different folder for any specific command using the --folder-name or --folder-id parameter.

See the description of the CLI command for updating bucket settings:
```
yc storage bucket update --help
```

Get a list of buckets in the default folder:

yc storage bucket list

Result:

+------------------+----------------------+----------+-----------------------+---------------------+
|       NAME       |      FOLDER ID       | MAX SIZE | DEFAULT STORAGE CLASS |     CREATED AT      |
+------------------+----------------------+----------+-----------------------+---------------------+
| my-bucket        | b1gmit33ngp3******** | 10       | STANDARD              | 2022-12-16 13:58:18 |
+------------------+----------------------+----------+-----------------------+---------------------+

Add labels, specifying the name of the bucket in question:

yc storage bucket update <bucket_name> \
  --tags <label_1_key>=<label_1_value>,<label_2_key>=<label_2_value>,...,<label_n_key>=<label_n_value>

Where --tags is a parameter to list bucket labels in key=value format.

Result:

name: my-bucket
folder_id: b1gmit33ngp3********
default_storage_class: STANDARD
versioning: VERSIONING_ENABLED
acl: {}
created_at: "2023-04-24T14:15:28.240705Z"
tags:
  - key: key-tag
    value: key-value

Warning

Updating the bucket settings will completely overwrite the existing labels.

If you do not have the AWS CLI yet, install and configure it.

In the terminal, run this command:

aws s3api put-bucket-tagging \
  --bucket <bucket_name> \
  --tagging 'TagSet=[{Key=<label_key>,Value=<label_value>},{Key=<label_key>,Value=<label_value>}]' \
  --endpoint-url=https://storage.yandexcloud.net

Where:

--bucket: Bucket name.
--tagging: Array of bucket labels, where:
- Key: Label key, the string type.
- Value: Label value, the string type.
--endpoint-url: Object Storage endpoint.

Warning

Updating the bucket settings will completely overwrite the existing labels.

Note

Terraform uses a service account to interact with Object Storage. Assign to the service account the required role, e.g., storage.admin, for the folder where you are going to create resources.

With Terraform, you can quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. These files store the infrastructure description written in HashiCorp Configuration Language (HCL). If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

Terraform is distributed under the Business Source License. The Yandex Cloud provider for Terraform is distributed under the MPL-2.0 license.

For more information about the provider resources, see the relevant documentation on the Terraform website or its mirror.

If you do not have Terraform yet, install it and configure the Yandex Cloud provider.

Open the Terraform configuration file and add the tags section to the bucket description:
```
resource "yandex_storage_bucket" "test-bucket" {
  bucket           = "<bucket_name>"
  ...
  tags             = {
    <label_1_key> = "<label_1_value>"
    <label_2_key> = "<label_2_value>"
  }
  ...
}
```
Where tags is the array of bucket labels in <key> = "<value>" format.

For more information about the yandex_storage_bucket resource in Terraform, see this TF provider article.
Apply the changes:
1. In the terminal, go to the directory where you edited the configuration file.
2. Make sure the configuration file is correct using this command:
```
terraform validate
```
  If the configuration is correct, you will get this message:
```
Success! The configuration is valid.
```
3. Run this command:
```
terraform plan
```
  You will see a detailed list of resources. No changes will be made at this step. If the configuration contains any errors, Terraform will show them.
4. Apply the changes:
```
terraform apply
```
5. Type yes and press Enter to confirm the changes.

This will add the specified labels to your bucket. You can check the new labels and the bucket settings using the management console or this CLI command:

yc storage bucket get <bucket_name> --full

Warning

Updating the bucket settings will completely overwrite the existing labels.

To add or update bucket labels, use the update REST API method for the Bucket resource, the BucketService/Update gRPC API call, or the putBucketTagging S3 API method.

Example of a gRPC API call

export IAM_TOKEN="<IAM_token>"
grpcurl \
  -H "Authorization: Bearer $IAM_TOKEN" \
  -d '{"name": "test-bucket", "update_mask": {"paths": ["tags"]}, "tags": [{"key": "test-key", "value": "test-value"}]}' \
  storage.api.cloud.yandex.net:443 \
  yandex.cloud.storage.v1.BucketService/Update

Where:

IAM_TOKEN: IAM token.
name: Bucket name.
update_mask: List of bucket parameters you want to update.
tags: List of bucket labels.
key: Label key.
value: Label value.

Result:

Delete labels, specifying the name of the bucket in question:

yc storage bucket update <bucket_name> \
  --remove-tags

Result:

name: my-bucket
folder_id: b1gmit33ngp3********
default_storage_class: STANDARD
versioning: VERSIONING_ENABLED
acl: {}
created_at: "2023-04-24T14:15:28.240705Z"

If you do not have the AWS CLI yet, install and configure it.

In the terminal, run this command:

aws s3api delete-bucket-tagging \
  --bucket <bucket_name> \
  --endpoint-url=https://storage.yandexcloud.net

Where:

--bucket: Bucket name.
--endpoint-url: Object Storage endpoint.

Note

Terraform uses a service account to interact with Object Storage. Assign to the service account the required role, e.g., storage.admin, for the folder where you are going to create resources.

If you do not have Terraform yet, install it and configure the Yandex Cloud provider.

Open the Terraform configuration file and delete the tags section from the bucket description.

Example of a bucket label description in Terraform configuration

resource "yandex_storage_bucket" "test-bucket" {
  bucket           = "<bucket_name>"
  ...
  tags             = {
    <label_1_key> = "<label_1_value>"
    <label_2_key> = "<label_2_value>"
  }
  ...
}

Apply the changes:
1. In the terminal, go to the directory where you edited the configuration file.
2. Make sure the configuration file is correct using this command:
```
terraform validate
```
  If the configuration is correct, you will get this message:
```
Success! The configuration is valid.
```
3. Run this command:
```
terraform plan
```
  You will see a detailed list of resources. No changes will be made at this step. If the configuration contains any errors, Terraform will show them.
4. Apply the changes:
```
terraform apply
```
5. Type yes and press Enter to confirm the changes.

This will delete the bucket labels. You can check the label deletion and the bucket settings using the management console or this CLI command:

yc storage bucket get <bucket_name> --full

To delete bucket labels, use the update REST API method for the Bucket resource, the BucketService/Update gRPC API call, or the deleteBucketTagging S3 API method.

Example of a gRPC API call

export IAM_TOKEN="<IAM_token>"
grpcurl \
  -H "Authorization: Bearer $IAM_TOKEN" \
  -d '{"name": "test-bucket", "update_mask": {"paths": ["tags"]}, "tags": []}' \
  storage.api.cloud.yandex.net:443 \
  yandex.cloud.storage.v1.BucketService/Update

Where:

IAM_TOKEN: IAM token.
name: Bucket name.
update_mask: List of bucket parameters you want to update.
tags: List of bucket labels.
