A bucket is a container used to store objects in Object Storage Service (OSS). All objects in OSS are stored in buckets. This topic describes how to create a bucket.
Usage notes
In this topic, the public endpoint of the China (Hangzhou) region is used. If you want to access OSS from other Alibaba Cloud services in the same region as OSS, use an internal endpoint. For more information about OSS regions and endpoints, see Regions, endpoints and open ports.
In this topic, access credentials are obtained from environment variables. For more information about how to configure access credentials, see Configure access credentials.
In this topic, an OSSClient instance is created by using an OSS endpoint. If you want to create an OSSClient instance by using custom domain names or Security Token Service (STS), see Initialization.
To create a bucket, you must have the
oss:PutBucketpermission. For more information, see Attach a custom policy to a RAM user.
Examples
The following sample code provides an example on how to create a bucket named examplebucket:
# -*- coding: utf-8 -*-
import oss2
from oss2.credentials import EnvironmentVariableCredentialsProvider
# Obtain access credentials from the environment variables. Before you run this sample code, make sure that you have configured environment variables OSS_ACCESS_KEY_ID and OSS_ACCESS_KEY_SECRET.
auth = oss2.ProviderAuthV4(EnvironmentVariableCredentialsProvider())
# Specify the endpoint of the region in which the bucket is located. For example, if the bucket is located in the China (Hangzhou) region, set the endpoint to https://oss-cn-hangzhou.aliyuncs.com.
endpoint = "https://oss-cn-hangzhou.aliyuncs.com"
# Specify the ID of the region that maps to the endpoint. Example: cn-hangzhou. This parameter is required if you use the signature algorithm V4.
region = "cn-hangzhou"
# Specify the name of your bucket.
bucket = oss2.Bucket(auth, endpoint, "yourBucketName", region=region)
# Create the bucket.
# The following sample code provides an example on how to specify the storage class, access control list (ACL), and redundancy type when you create the bucket.
# In this example, the storage class is Standard, the ACL is private, and the redundancy type is zone-redundant storage (ZRS).
# bucketConfig = oss2.models.BucketCreateConfig(oss2.BUCKET_STORAGE_CLASS_STANDARD, oss2.BUCKET_DATA_REDUNDANCY_TYPE_ZRS)
# bucket.create_bucket(oss2.BUCKET_ACL_PRIVATE, bucketConfig)
bucket.create_bucket()
