Error while creating a blob container

Question

Hi all,

i am using following code to create a container in local dev env.

_account = CloudStorageAccount.FromConfigurationSetting("DataConnectionString");

_client = _account.CreateCloudBlobClient();

_gbsContainer = RoleEnvironment.GetConfigurationSettingValue("ContainerName");

_blobContainer = _client.GetContainerReference(_gbsContainer);

bool status = _blobContainer.CreateIfNotExist();

but the highlighted line throws an exception :

Microsoft.WindowsAzure.StorageClient.StorageClientException was caught
  Message="One of the request inputs is out of range."
  Source="Microsoft.WindowsAzure.StorageClient"
  StackTrace:

Hi Vinayak,

Can you share the name of the blob container you're trying to create? In general here are the rules for naming a blob container:

The blob container name must be a valid DNS name, confirming to the following naming rules:

1. Blob container names must start with a letter or number, and can contain only letters, numbers, and the dash (-) character.

2. Every dash (-) character must be immediately preceded and followed by a letter or number.

3. All letters in a container name must be lowercase.

4. Blob container names must be from 3 through 63 characters long.

Hope this helps.

Thanks

Hi Gaurav,

Thank You for your reply!!

The container name that i used was test.container. Notice the (.) seperating two words. But i was really undone by the instructions in Azure training kit that mentioned the following:

The container name must be a valid Domain Name System (DNS) name, conforming to the following naming rules:
- Must start with a letter or number, and can contain only letters, numbers, and the period (.) and dash(-) characters.
- All letters must be lowercase.
- Must be from 3 to 63 characters long.
- A name cannot contain a dash next to a period.

Azure guys : You should really be reviewing the content you put on training kit.

Correcting the container name worked for me.

Thanks once again gaurav.

Vinayak.

Answer 3

I'll pass this along to the folks who own the Training Kit.

Yes Steve, that would help save some time of other startup guys.
