[1] Add a user for using Swift on Keystone Control Node.
By the way, if you'd like to use Swift Quickly, it's unnecessary to add a new user, it's possible to use with existing admin or swift user on Keystone.

# add the user to [SwiftOperator] role

root@dlp ~(keystone)#

[2] Work on a Client from here and later.
Install Keystoneclient, Swiftclient on a Client first.
root@client:~#
apt -y install python3-openstackclient python3-keystoneclient python3-swiftclient
[3] Load environment variables first. ( it's the value for a user added in [1] )

[7] Delete a file on Swift Storage.
debian@client ~(swift)$
openstack object delete test-container testfile.txt

openstack object list test-container

# [testfile.txt] has been removed

[8] Delete a Container on Swift Storage.
debian@client ~(swift)$
openstack container delete test-container
