The two main concepts when using Swift are containers and objects. Containers are groups of files that contain objects. Objects are simply files and must exist inside of a container. On the Swift command line, you cannot create an empty container. A container is created when the first object is uploaded to it. Make sure that your keystonerc file is sourced, and start by uploading a file to a container. Let's use the packstack.txt file used for installation as an example file to upload:

control# swift upload my_container packstack.txt
control# swift list
control# swift list my_container

You will notice that the list command is used to list both containers and objects. If you don't pass any arguments to the list command, you will get a list of containers. If you pass a container as an argument, you will get a list of the objects in that container. Next, upload the same file, but use its absolute path to upload it, as follows:

control# swift upload my_container...
