How to Configure awscli for Use with Storm Object Storage

Storm Object Storage delivers a durable, secure, highly available solution for storage needs of virtually any size. With object storage access occurs via API calls to the object storage cluster, which replaces the need to rely on additional servers for dedicated storage.

You will then be prompted twice more for:

Default region name [None]:


Default output format [None]:

You do not have to add any information to the last two prompts. Simply hit Enter at each prompt.

The information you entered above will end up in the following configuration file:



Newer versions of communication have a default signature version setting of “s3v4” which is incompatible with Storm Object Storage. Use the following command to update the default signature version to the supported “s3” setting:aws configure set default.s3.signature_version s3
