Updating the metadata for a container

This section describes how to add or update metadata for a container. Examples showing how to update X-Container-Meta-Countries are covered in the following sections.

Using the Swift client CLI

In this example, we are adding metadata for the countries that we have visited. Execute the following request:

-H "X-Container-Meta-Countries: visited"
swift --os-auth-token=token --os-storage-url= 
http://storage.vedams.com/v1/AUTH_8e43ee201cbc4b70bd8bb2f8ae10f025 post countries 
-H "X-Container-Meta-Countries: visited"

Using the REST API

Here we are adding metadata using the REST API.

Execute this request:

Method : POST

URL    : http://storage.vedams.com/v1/AUTH_8e43ee201cbc4b70bd8bb2f8ae10f025/countries

Header :  X-Auth-Token: token
              X-Container-Meta-Countries: visited
Data   : No content
