OpenStack Epoxy : How to use Swift

This section shows how to use Swift Storage from Clients. This example is based on the environment like follows. ------------+--------------------------+------------ | | eth0|10.0.0.30 eth0|10.0.0.50 +-----------+-----------+ +-----------+-----------+ | [ dlp.srv.world ] | | [ network.srv.world ] | | (Control Node) | | (Proxy Node) | | | | | | MariaDB RabbitMQ | | Swift Proxy | | Memcached Nginx | | Nginx | | Keystone httpd | | | +-----------------------+ +-----------------------+ ------------+--------------------------+--------------------------+----------- eth0|10.0.0.71 eth0|10.0.0.72 eth0|10.0.0.73 +-----------+-----------+ +-----------+-----------+ +-----------+-----------+ | [snode01.srv.world] | | [snode02.srv.world] | | [snode03.srv.world] | | (Storage Node#1) | | (Storage Node#2) | | (Storage Node#3) | | | | | | | | Swift-Account | | Swift-Account | | Swift-Account | | Swift-Container | | Swift-Container | | Swift-Container | | Swift-Object | | Swift-Object | | Swift-Object | +-----------------------+ +-----------------------+ +-----------------------+

[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.

# create [swiftservice] project root@dlp ~(keystone)#  openstack project create --domain default --description "Swift Service Project" swiftservice +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | Swift Service Project | | domain_id | default | | enabled | True | | id | ea5ee4b3cdbd4bbaa832f1eb9ece4598 | | is_domain | False | | name | swiftservice | | options | {} | | parent_id | default | | tags | [] | +-------------+----------------------------------+ # create [swiftoperator] role root@dlp ~(keystone)#  openstack role create swiftoperator +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | id | a5c1b36ac7c0485b9e564a97954fe5b8 | | name | swiftoperator | | domain_id | None | | description | None | +-------------+----------------------------------+ # add a user root@dlp ~(keystone)#  openstack user create --domain default --project swiftservice --password userpassword swiftuser01 +---------------------+----------------------------------+ | Field | Value | +---------------------+----------------------------------+ | default_project_id | ea5ee4b3cdbd4bbaa832f1eb9ece4598 | | domain_id | default | | email | None | | enabled | True | | id | dc6eed5b379d48b6934666e5353c4128 | | name | swiftuser01 | | description | None | | password_expires_at | None | +---------------------+----------------------------------+ # 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 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=https://dlp.srv.world: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 ubuntu@client ~(swift)$  echo "source ~/keystonerc_swift " >> ~/.bash_profile # verify status ubuntu@client ~(swift)$  swift stat Account: AUTH_7f02de02c70a4c7c8f95eb5c86201869 Containers: 0 Objects: 0 Bytes: 0 Content-Type: text/plain; charset=utf-8 X-Timestamp: 1756694779.75885 X-Put-Timestamp: 1756694779.75885 Vary: Accept X-Trans-Id: txab8d9878d04a4853b15ae-0068b508fb X-Openstack-Request-Id: txab8d9878d04a4853b15ae-0068b508fb

[4]	Create a Container for saving files.

debian@client ~(swift)$  openstack container create test-container +------------------------------+----------------+------------------------------+ | account | container | x-trans-id | +------------------------------+----------------+------------------------------+ | AUTH_7f02de02c70a4c7c8f95eb5 | test-container | txe9aa8f1cc0a44a7d8bf4e- | | c86201869 | | 0068b50913 | +------------------------------+----------------+------------------------------+ debian@client ~(swift)$  openstack container list +----------------+ | Name | +----------------+ | test-container | +----------------+

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

# upload [testfile.txt] debian@client ~(swift)$  echo testfile > testfile.txt debian@client ~(swift)$  openstack object create test-container testfile.txt +--------------+----------------+----------------------------------+ | object | container | etag | +--------------+----------------+----------------------------------+ | testfile.txt | test-container | e9409172a4036cc688f169c72131e921 | +--------------+----------------+----------------------------------+ debian@client ~(swift)$  openstack object list test-container +--------------+ | Name | +--------------+ | testfile.txt | +--------------+

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

debian@client ~(swift)$  rm testfile.txt debian@client ~(swift)$  openstack object save test-container testfile.txt debian@client ~(swift)$  ll total 8 -rw------- 1 debian debian 286 Sep 1 11:46 keystonerc_swift -rw-rw-r-- 1 debian debian 9 Sep 1 11:49 testfile.txt

[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 # [test-container] has been removed
