AWS Command Line Interface (AWS CLI)

The AWS CLI is a command line interface designed for AWS services. To learn how to run commands, see the official Amazon documentation.

To work with Object Storage via the AWS CLI, you can use the following commands:

• s3api: Commands corresponding to operations in the REST API. Before you start, look through the list of supported operations.
• s3: Additional commands that make it easier to work with a large number of objects.

Getting startedGetting started

1. Create a service account.

2. Assign to the service account the roles required for your project, e.g., storage.editor for a bucket (to work with a particular bucket) or a folder (to work with all buckets in this folder). For more information about roles, see Access management with Yandex Identity and Access Management.

   To work with objects in an encrypted bucket, a user or service account must have the following roles for the encryption key in addition to the storage.configurer role:

   • kms.keys.encrypter: To read the key, encrypt and upload objects.
   • kms.keys.decrypter: To read the key, decrypt and download objects.
   • kms.keys.encrypterDecrypter: This role includes the kms.keys.encrypter and kms.keys.decrypter permissions.

   For more information, see Key Management Service service roles.

3. Create a static access key.

   As a result, you will get the static access key data. To authenticate in Object Storage, you will need the following:

   • key_id: Static access key ID
   • secret: Secret key

   Save key_id and secret: you will not be able to get the key value again.

InstallationInstallation

To install the AWS CLI, follow the guide on the vendor's website.

ConfigurationConfiguration

To configure the AWS CLI, run the aws configure command in your terminal. The command will request values for the following parameters:

1. AWS Access Key ID: Static key ID you got previously.

2. AWS Secret Access Key: Static key contents you got previously.

3. Default region name: ru-central1.

   To work with Object Storage, always specify the ru-central1. A different region value may lead to an authorization error.

4. Leave the other parameters unchanged.

Configuration filesConfiguration files

The aws configure command saves the static key and the region.

• The static key in .aws/credentials has the following format:

  [default]
  aws_access_key_id = <static_key_ID>
  aws_secret_access_key = <static_key_contents>
  

• The default region in .aws/config has the following format:

  [default]
  region = ru-central1
  

• You can create multiple profiles for different service accounts by specifying their details in the .aws/credentials file:

  [default]
  aws_access_key_id = <ID_of_static_key_1>
  aws_secret_access_key = <contents_of_static_key_1>
  [<name_of_profile_2>]
  aws_access_key_id = <ID_of_static_key_2>
  aws_secret_access_key = <contents_of_static_key_2>
  ...
  [<name_of_profile_n>]
  aws_access_key_id = <ID_of_static_key_n>
  aws_secret_access_key = <contents_of_static_key_n>
  

  Where default is the default profile.

  To switch between profiles, the AWS CLI commands use the --profile option, e.g.:

  aws --endpoint-url=https://storage.yandexcloud.net/ \
    --profile <name_of_profile_2> \
    s3 mb s3://<bucket_name>
  

You can use Yandex Lockbox to safely store the static key for access to Object Storage. For more information, see Using a Yandex Lockbox secret to store a static access key.

FeaturesFeatures

Take note of these AWS CLI features when used with Object Storage:

• The AWS CLI treats Object Storage as a hierarchical file system and object keys look like file paths.
• By default, the client is configured to work with Amazon servers. Therefore, when running the aws command to work with Object Storage, make sure to use the --endpoint-url parameter. To avoid adding the parameter manually each time you run the command, you can use a configuration file or an alias.

  • In the .aws/config configuration file, add the endpoint_url parameter (this is supported by the AWS CLI versions 1.29.0, 2.13.0, and higher):

    endpoint_url = https://storage.yandexcloud.net
    

    This enables you to invoke commands without explicitly specifying an endpoint. For example, you can specify aws s3 ls instead of aws --endpoint-url=https://storage.yandexcloud.net s3 ls. For more information, see the AWS CLI documentation.

  • Create an alias using the following command:

    alias ycs3='aws s3 --endpoint-url=https://storage.yandexcloud.net'
    

    To create an alias each time you open the terminal, add the alias command to the configuration file, which can be either ~/.bashrc or ~/.zshrc, depending on the type of shell you are using.

    When using this alias, the following commands are equivalent:

    aws s3 --endpoint-url=https://storage.yandexcloud.net ls
    

    ycs3 ls
    

Examples of operationsExamples of operations

Creating a bucketCreating a bucket

aws s3 mb s3://bucket-name

Result:

make_bucket: bucket-name

Uploading objectsUploading objects

You can upload all objects within a directory, use a filter, or upload objects one at a time.

• Upload all objects from a local directory:

  aws s3 cp --recursive local_files/ s3://bucket-name/path_style_prefix/
  

  Result:

  upload: ./textfile1.log to s3://bucket-name/path_style_prefix/textfile1.log
  upload: ./textfile2.txt to s3://bucket-name/path_style_prefix/textfile2.txt
  upload: ./prefix/textfile3.txt to s3://bucket-name/path_style_prefix/prefix/textfile3.txt
  

• Upload objects specified in the --include filter and skip objects specified in the --exclude filter:

  aws s3 cp --recursive --exclude "*" --include "*.log" \
    local_files/ s3://bucket-name/path_style_prefix/
  

  Result:

  upload: ./textfile1.log to s3://bucket-name/path_style_prefix/textfile1.log
  

• Upload objects one by one, running the following command for each object:

  aws s3 cp testfile.txt s3://bucket-name/path_style_prefix/textfile.txt
  

  Result:

  upload: ./testfile.txt to s3://bucket-name/path_style_prefix/textfile.txt

Deleting objectsDeleting objects

You can delete all objects with a specified prefix, use a filter, or delete objects one at a time.

• Delete all objects with the specified prefix:

  aws s3 rm s3://bucket-name/path_style_prefix/ --recursive
  

  Result:

  delete: s3://bucket-name/path_style_prefix/test1.png
  delete: s3://bucket-name/path_style_prefix/subprefix/test2.png
  

• Delete objects specified in the --include filter and skip objects specified in the --exclude filter:

  aws s3 rm s3://bucket-name/path_style_prefix/ --recursive \
      --exclude "*" --include "*.log"
  

  Result:

  delete: s3://bucket-name/path_style_prefix/test1.log
  delete: s3://bucket-name/path_style_prefix/subprefix/test2.log
  

• Delete objects one by one, running the following command for each object:

  aws s3 rm s3://bucket-name/path_style_prefix/textfile.txt
  

  Result:

  delete: s3://bucket-name/path_style_prefix/textfile.txt
