OpenStack Zed : How to use Swift2023/06/29 |
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. |

|
[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:~$
