Create Container (REST API)
Updated: September 13, 2011
The Create Container operation creates a new container under the specified account. If the container with the same name already exists, the operation fails.
The container resource includes metadata and properties for that container. It does not include a list of the blobs contained by the container.
The Create Container request may be constructed as follows. HTTPS is recommended. Your mycontainer value can only include lower-case characters. Replace myaccount with the name of your storage account:
| Method | Request URI | HTTP Version |
|---|---|---|
|
PUT |
|
HTTP/1.1 |
Emulated Storage Service Request
When making a request against the emulated storage service, specify the emulator hostname and Blob service port as 127.0.0.1:10000, followed by the emulated storage account name:
| Method | Request URI | HTTP Version |
|---|---|---|
|
PUT |
|
HTTP/1.1 |
For more information, see About Development Storage.
URI Parameters
The following additional parameters may be specified on the request URI.
| Parameter | Description |

Request Headers
The following table describes required and optional request headers.
| Request Header | Description |

Sample Request
Request Syntax: PUT https://myaccount.blob.core.windows.net/mycontainer?restype=container HTTP/1.1 Request Headers: x-ms-version: 2011-08-18 x-ms-date: Sun, 25 Sep 2011 22:50:32 GMT x-ms-meta-Name: StorageSample Authorization: SharedKey myaccount:Z5043vY9MesKNh0PNtksNc9nbXSSqGHueE00JdjidOQ=
The response includes an HTTP status code and a set of response headers.
Status Code
A successful operation returns status code 201 (Created).
For information about status codes, see Status and Error Codes.
Response Headers
The response for this operation includes the following headers. The response may also include additional standard HTTP headers. All standard headers conform to the HTTP/1.1 protocol specification.
| Response header | Description |
|---|---|
|
ETag |
The ETag for the container. If the request version is 2011-08-18 or newer, the ETag value will be in quotes. |
|
Last-Modified |
Returns the date and time the container was last modified. The date format follows RFC 1123. For more information, see Representation of Date/Time Values in Headers. Any operation that modifies the container or its properties or metadata updates the last modified time. Operations on blobs do not affect the last modified time of the container. |
|
x-ms-request-id |
This header uniquely identifies the request that was made and can be used for troubleshooting the request. For more information, see Troubleshooting API Operations |
|
x-ms-version |
Indicates the version of the Blob service used to execute the request. This header is returned for requests made against version 2009-09-19 and later. |
|
Date |
A UTC date/time value generated by the service that indicates the time at which the response was initiated. |
Response Body
None.
Sample Response
Response Status: HTTP/1.1 201 Created Response Headers: Transfer-Encoding: chunked Date: Sun, 25 Sep 2011 23:00:12 GMT ETag: “0x8CB14C3E29B7E82” Last-Modified: Sun, 25 Sep 2011 23:00:06 GMT x-ms-version: 2011-08-18 Server: Windows-Azure-Blob/1.0 Microsoft-HTTPAPI/2.0
Only the account owner may call this operation.
Containers are created immediately beneath the storage account. It's not possible to nest one container beneath another.
You can optionally create a default or root container for your storage account. The root container may be inferred from a URL requesting a blob resource. The root container makes it possible to reference a blob from the top level of the storage account hierarchy, without referencing the container name.
To add the root container to your storage account, create a container named $root. Construct the request as follows:
Request Syntax: PUT https://myaccount.blob.core.windows.net/$root?restype=container HTTP/1.1 Request Headers: x-ms-version: 2011-08-18 x-ms-date: Sun, 25 Sep 2011 22:50:32 GMT x-ms-meta-Name: StorageSample Authorization: SharedKey myaccount:Z5043vY9MesKNh0PNtksNc9nbXSSqGHueE00JdjidOQ=
You can specify metadata for a container at the time it is created by including one or more metadata headers on the request. The format for the metadata header is x-ms-meta-name:value.
If a container by the same name is being deleted when Create Container is called, the server will return status code 409 (Conflict), with additional error information indicating that the container is being deleted.
