[1] Add a user for using Swift on Keystone Control Node.
If you'd like to use Swift quickly, it's unnecessary to add a new user, it's posibble to use with existing admin or swift user on Keystone.

# add the user to [SwiftOperator] role

root@dlp ~(keystone)#
openstack role add --project swiftservice --user swiftuser01 SwiftOperator
[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 just the value for a user added in [1] )
debian@client:~$
vi ~/keystonerc_swift
export OS_PROJECT_DOMAIN_NAME=default
export OS_USER_DOMAIN_NAME=default
export OS_PROJECT_NAME=swiftservice
export OS_USERNAME=swiftuser01
export OS_PASSWORD=userpassword
export OS_AUTH_URL=http://10.0.0.30:5000/v3
export OS_IDENTITY_API_VERSION=3
export PS1='\u@\h \W(swift)\$ '
debian@client:~$
chmod 600 ~/keystonerc_swift

debian@client:~$
source ~/keystonerc_swift

debian@client ~(swift)$
echo "source ~/keystonerc_swift " >> ~/.bashrc
# verify status

debian@client ~(swift)$
swift stat

[4] Create a Container for saving files.
debian@client ~(swift)$
openstack container create test-container

debian@client ~(swift)$
openstack container list

[6] Download a file from Swift Storage to local.
debian@client ~(swift)$

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

debian@client ~(swift)$
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

debian@client ~(swift)$
openstack container list
