OpenStack Victoria : How to use Swift2021/09/02 |
|
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 |
+-----------+-----------+ +-----------+-----------+ |
| [ Control Node ] | | [ Proxy Node ] | |
| | | | |
| MariaDB RabbitMQ | | Swift Proxy | |
| Memcached httpd | | | |
| Keystone | | | |
+-----------------------+ +-----------------------+ |
|
------------+---------------------------+-------------+-------------+-----------
eth0|10.0.0.71 eth0|10.0.0.72 eth0|10.0.0.73
+-----------+-----------+ +-----------+-----------+ +-----------+-----------+
| [ 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. If you'd like to use Swift quickly, it's unnecessary 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 python3-openstackclient python3-keystoneclient python3-swiftclient
|
| [3] | Load environment variables first. ( it's just the value for a user added in [1] ) |
