Get Auth Token
First all you will need to obtain the Auth Token. This token will be used to perform further actions via the API.
For this you will need to obtain your API Key which can be found from the Rackspace Cloud Portal.
curl -s -X 'POST' \
-d '{"auth":{"RAX-KSKEY:apiKeyCredentials":{"username":"<USERNAME>", "apiKey":"<API KEY>"}}}' \
-H "Content-Type: application/json" | python -m json.tool
Below shows an example. I have highlighted the Auth Token and the Cloudfile public URL. Both of which you will need within the next step(s).
[root@server ~]# curl -s -X 'POST' \
> -d '{"auth":{"RAX-KSKEY:apiKeyCredentials":{"username":"<USERNAME>", "apiKey":"<API KEY>"}}}' \
> -H "Content-Type: application/json" | python -m json.tool

}List Containers
To list the Cloud File containers we can use the following command.
curl -H "X-Auth-Token: <AUTH TOKEN>" https://storage101.lon3.clouddrive.com/v1/MossoCloudFS_e69 726fd-c72e-4873-b8ae-45dfd1a755fa
Purge File
To purge the file the following command is used. Once this has been actioned an email will be sent to the email address supplied below.
curl -X DELETE -H "X-Purge-Email: <YOUR EMAIL ADDRESS>" -H "X-Auth-Token: <AUTH TOKEN>" https://cdn3.clouddrive.com/v1/MossoCloudFS_e69726fd-c72e-4873-b8ae- 45dfda7755fa/images/legacy/oldimage.png
Download File
As a side note to download the file the following command would be used.
curl -XGET -H "X-Auth-Token: <AUTH TOKEN>" https://cdn3.clouddrive.com/v1/MossoCloudFS_e69726fd-c72e-4873-b8ae- 45dfda7755fa/images/legacy/oldimage.png > oldimage.png
