This guide describes initial settings and brief instructions for Object Storage CLI, which is compatible with Amazon S3 CLI.

Initial settings

It describes how you can install and authenticate Object Storage CLI to use it.

Installation

The installation command is as follows:

pip install awscli==1.15.85

Note

Since awscli version 1.16.x does not support some features, we recommend using version 1.15.x.
awscli version 1.15.85 supports Python 3.8 or earlier.
See the following for related documents.
- Document: https://pypi.org/project/awscli/1.15.85/
- git: https://github.com/aws/aws-cli/tree/1.15.85

Authentication

The following describes how to set the authentication information.

~$ aws configure
AWS Access Key ID [****************leLy]: ACCESS_KEY_ID
AWS Secret Access Key [None]: SECRET_KEY
Default region name [None]: [Enter]
Default output format [None]: [Enter]

Cautions

It describes precautions when using it in servers with assigned roles. Servers with assigned roles can use Object Storage commands without additional configurations.
When using in servers with assigned roles, use the authentication key search API among the Metadata APIs. However, since a timeout can occur during this process, you can use the following command to extend the Metadata API timeout if necessary.

export AWS_METADATA_SERVICE_TIMEOUT=10

When using CLIs, the --endpoint-url option is a required value. For calling domains by region, see the Object Storage API guide.

Command help

Run the following command to check the help for smooth use of Object Storage CLI.

aws help
aws <command> help
aws <command> <subcommand> help

Delete bucket

The following is the command to delete a bucket.

API-level

aws --endpoint-url=https://kr.object.ncloudstorage.com s3api delete-bucket --bucket <bucket_name>

Note

Buckets that are not empty can't be deleted at the API-level.

Sync

The sync feature can only be performed with the high-level command. If you use the --delete option, then the files that don't exist in the source are also deleted in the destination. The sync command is as follows:

high-level

Sync all files in a bucket (folder) of the Object Storage to a local directory

aws --endpoint-url=https://kr.object.ncloudstorage.com s3 sync s3://<bucket_name>[/<object_name>] <local_directory_name>

Sync all files in a local directory to a bucket (folder) of the Object Storage

aws --endpoint-url=https://kr.object.ncloudstorage.com s3 sync <local_directory_name> s3://<bucket_name>[/<object_name>]

Sync all files in a bucket (folder) of the Object Storage to another bucket (folder)
```
aws --endpoint-url=https://kr.object.ncloudstorage.com s3 sync s3://<source_bucket_name>[/<destination_object_name>] s3://<destination_bucket_name>[/<destination_object_name>]
```
Note
For awscli version 2, we recommend using version 1.15.x. because running the sync command can result in errors due to calling unsupported APIs.

Access control list (ACL)

You can set access control list (ACL) permissions for files in an Object Storage bucket (folder). The ACL feature can only be performed with the API-level command. The command is as follows:

API-level

Set the files in the Object Storage bucket as public

aws --endpoint-url=https://kr.object.ncloudstorage.com s3api put-object-acl --bucket <bucket_name> --key <object_name> --acl public-read

Set the files in an Object Storage bucket as private

aws --endpoint-url=https://kr.object.ncloudstorage.com s3api put-object-acl --bucket <bucket_name> --key <object_name> --acl private

By using it with search list command (ls), you can set all files uploaded to an Object Storage bucket (folder) public. The command is as follows:

Set all files in the Object Storage bucket as public

Caution

This is a public setting for all files in the bucket, so be careful when executing the command.

aws --endpoint-url=https://kr.object.ncloudstorage.com/ s3 ls s3://<bucket_name> --recursive | awk '{cmd="aws --endpoint-url=https://kr.object.ncloudstorage.com/ s3api put-object-acl --bucket <bucket_name> --acl public-read --key "$4; system(cmd)}'

Debugging

The commands related to debugging are as follows:

View detailed logs using the --debug* option

aws --endpoint-url=https://kr.object.ncloudstorage.com s3 cp <local_file_path> s3://<bucket_name>[/<object_name>] --debug

Save as a log file

aws --endpoint-url=https://kr.object.ncloudstorage.com s3 cp <local_file_path> s3://<bucket_name>[/<object_name>] --debug 2> debug.log

Set CORS

It sets CORS (Cross-Origin Resource Sharing) for an Object Storage bucket. Once an Object Storage bucket receives a cross-origin request, it checks the CORS configuration and allows the cross-origin request using the first CORS rule that matches the browser request. The following conditions have to be met for a CORS rule to be matched.

The request's Origin header must match the AllowedOrigins element.
The request method or Access-Control-Request-Method header (preflight request) must match the AllowedMethods element.
All headers specified in the Access-Control-Request-Method header (preflight request) must match the AllowedHeaders element. CORS configuration can only be done by the API-level command.

The command is as follows:

API-level

Set CORS rules defined with a JSON file to the Object Storage bucket

aws --endpoint-url=https://kr.object.ncloudstorage.com s3api put-bucket-cors --bucket <bucket_name> --cors-configuration file://cors.json

cors.json:
{
  "CORSRules": [
  {
      "AllowedHeaders": ["*"],
      "AllowedMethods": ["GET","PUT"],
      "AllowedOrigins": ["*"],
      "MaxAgeSeconds": 3000
    }
  ]
}

Search the CORS rule set in the Object Storage bucket

aws --endpoint-url=https://kr.object.ncloudstorage.com s3api get-bucket-cors --bucket <bucket_name>
