OpenStack Wallaby : How to use Swift2021/04/26 |
|
This section shows how to use Swift Storage from Clients.
This example is based on the emvironment like follows.
------------+--------------------------+-------------+-----

eth0|10.0.0.30 eth0|10.0.0.50 |
+-----------+-----------+ +-----------+-----------+ |
| [ Control Node ] | | [ Proxy Node ] | |
| | | | |
| MariaDB RabbitMQ | | Swift Proxy | |
| Memcached httpd | | | |
| Keystone | | | |
+-----------------------+ +-----------------------+ |

| [ Storage Node#1 ] | | [ Storage Node#2 ] | | [ Storage Node#3 ] |

| 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 posibble to use with existing admin or swift user on Keystone. |

| [2] | Work on a Client Host from here and later. Install Keystoneclient, Swiftclient on a Client Host first. |
|
[root@client ~]# dnf --enablerepo=centos-openstack-wallaby,powertools,epel -y install python3-openstackclient python3-keystoneclient python3-swiftclient
|
| [3] | Load environment variables first. ( it's just the value for a user added in [1] ) |
|
[root@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=http://10.0.0.30:5000/v3 export OS_IDENTITY_API_VERSION=3 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
