[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.

# add swiftservice tenant

[root@dlp ~(keystone)]#

keystone tenant-create --name swiftservice --description "Swift Users Tenant" --enabled true

+-------------+----------------------------------+
|   Property  |              Value               |
+-------------+----------------------------------+
| description |        Swift Users Tenant        |
|   enabled   |               True               |
|      id     | 5fd688cd14ac4fd1ba54d817f723c4b9 |
|     name    |           swiftservice           |
+-------------+----------------------------------+

# add swiftoperator role

[root@dlp ~(keystone)]#

keystone role-create --name swiftoperator

+----------+----------------------------------+
| Property |              Value               |

+----------+----------------------------------+

# add a user

[root@dlp ~(keystone)]#

keystone user-create --tenant swiftservice --name user01 --pass userpassword --enabled true

+----------+----------------------------------+

# add the user in swiftoperator role

[root@dlp ~(keystone)]#

keystone user-role-add --user user01 --tenant swiftservice --role swiftoperator

[2]	Work on a Client from here and later. Install Keystoneclient, Swiftclient on a Client first.

# install from RDO, EPEL

[root@client ~]#

yum --enablerepo=openstack-juno,epel -y install python-keystoneclient python-swiftclient

[3]	Load environment variables first. ( it's just the value for a user added in [1] )

[root@client ~]#

vi ~/keystonerc_swift

export OS_USERNAME=user01
export OS_PASSWORD=userpassword
export OS_TENANT_NAME=swiftservice
export OS_AUTH_URL=http://10.0.0.30:35357/v2.0/
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

# display status

[root@client ~(swift)]#

swift stat

[4]	Create a Container for saving files.

[root@client ~(swift)]#

swift post test_container

[root@client ~(swift)]#

swift list

test_container

# just created

[5]	Upload a file on local to the Container.

# upload test.txt

[root@client ~(swift)]#

swift upload test_container test.txt

test.txt
[root@client ~(swift)]#

swift list test_container

test.txt

# just uploaded

[6]	Download a file from Swift Storage to local.

# remove a file

[root@client ~(swift)]#

rm test.txt

[root@client ~(swift)]#

swift download test_container test.txt

test.txt [auth 0.245s, headers 0.495s, total 0.495s, 0.000 MB/s]
[root@client ~(swift)]#

-rw-------  1 root root 175 Jan 15 01:58 keystonerc_swift
-rw-r--r--  1 root root  10 Jan 15 01:59 test.txt

[7]	Delete a file on Swift Storage.

[root@client ~(swift)]#

swift delete test_container test.txt

test.txt
[root@client ~(swift)]#

swift list test_container

test2.txt

# test.txt is just deleted

[8]	Delete a Container on Swift Storage.

[root@client ~(swift)]#

swift delete test_container

[root@client ~(swift)]#

swift list

# just deleted
