OpenStack Icehouse : How to use Swift Storage
2014/06/11 |
This section shows how to use Swift Storage from Clients.
This example shows to configure like the environment below.
| +------------------+ | +-----------------+ | [ Control Node ] |10.0.0.30 | 10.0.0.70| [ Proxy Node ] | | Keystone |-----------+-----------| | +------------------+ | +-----------------+ +-----------------+ | 10.0.0.20| [ ClientPC ] | +---------------------------+--------------------------+---------------| | | | | +-----------------+ |10.0.0.71 |10.0.0.72 |10.0.0.73 +-------+----------+ +--------+---------+ +--------+---------+ | [Storage Node#1] | | [Storage Node#2] | | [Storage Node#3] | | |-------| |-------| | +------------------+ +------------------+ +------------------+ |
[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 | e6e814b2cbc143f7991ed0613438611d | | name | swiftservice | +-------------+----------------------------------+ # add swiftoperator role root@dlp ~(keystone)# keystone role-create --name swiftoperator +----------+----------------------------------+ | Property | Value | +----------+----------------------------------+ | id | 2c3b49e3cd8546bc977695997ee58a5b | | name | swiftoperator | +----------+----------------------------------+ # add a user root@dlp ~(keystone)# keystone user-create --tenant swiftservice --name user01 --pass userpassword --enabled true +----------+----------------------------------+ | Property | Value | +----------+----------------------------------+ | email | | | enabled | True | | id | a68557e54abc4a92b915efb4ee164f65 | | name | user01 | | tenantId | e6e814b2cbc143f7991ed0613438611d | | username | user01 | +----------+----------------------------------+ # 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. |
root@client:~# apt-get -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
# show status root@client ~(swift)# swift stat Account: AUTH_e6e814b2cbc143f7991ed0613438611d Containers: 0 Objects: 0 Bytes: 0 Content-Type: text/plain; charset=utf-8 X-Timestamp: 1402501124.33015 X-Trans-Id: txd0ad784505d04456be71e-0053987804 X-Put-Timestamp: 1402501124.33015 |
[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. |
root@client ~(swift)# swift download test_container test.txt test.txt [auth 0.187s, headers 0.243s, total 0.244s, 0.000 MB/s] root@client ~(swift)# total 8 -rw------- 1 root root 173 Jun 12 00:25 keystonerc_swift -rw-r--r-- 1 root root 14 Jun 12 00:41 test.txt |
[7] | Delere 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 |
