This section shows how to use Swift Storage from Clients.
This example is based on the emvironment like follows.
------------+---------------------------+-------------+---

eth0|10.0.0.30 eth0|10.0.0.50 |
+-----------+-----------+ +-----------+-----------+ |
| [ Control Node ] | | [ Proxy Node ] | |
| | | | |
| MariaDB RabbitMQ | | Swift Proxy | |
| Memcached httpd | | | |
| Keystone | | | |

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

| [2] | Work on a Client from here and later. Install Keystoneclient, Swiftclient on a Client first. |
|
root@client:~# apt -y install python-openstackclient python-keystoneclient python-swiftclient
|
| [3] | Login as a user and Load environment variables of the user for Swift added on [1] section. |
|
root@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)\$ '
root@client:~#
chmod 600 ~/keystonerc_swift root@client:~# source ~/keystonerc_swift root@client ~(swift)# echo "source ~/keystonerc_swift " >> ~/.bash_profile
