To store objects in COS, you first need to create a bucket through the console, tools, APIs, or SDKs.
After creating a bucket, you can upload objects to it and configure other features for it, such as setting up a static website, setting bucket tags, and setting bucket encryption. For more configuration guidelines, please see Console Overview.
You can create a bucket in the COS console. For more information, please see Creating Buckets.
You can use tools such as COSBrowser and COSCMD to create buckets. For more information, please see Tool Overview.
You can use the REST API directly to initiate a bucket creating request. For more information, please see PUT Bucket.
