OpenStackClient 是 OpenStack 提供的一个命令行CLI工具. OpenStackClient支持两种身份验证方式
通过用户名/密码验证
通过Token验证

下面通过两个例子, 演示怎样通过这两种不同的验证方式, 使用OpenStack Client获取nova的flavor列表

DEBUG: openstackclient.shell clean_up ListFlavor
1) 先用curl命令, 直接与keystone交互, 获得一个PKI格式的 scope token
$ curl -s -X POST http://127.0.0.1:5000/v2.0/tokens -H "Content-Type: application/json" -H "User-Agent: python-keystoneclient" -d '{"auth":{"tenantName": "admin", "passwordCredentials":{"username": "admin", "password":"passw0rd"}}}' |
python-mjson.tool
# Partial Result
{
"token": {
"expires": "2014-08-12T09:35:52Z",
"id": "<PKI Format Token>",
"issued_at": "2014-08-12T08:35:52.154208",
"tenant": {
"description": null,
"enabled": true,
"id": "71c452812dc845e3a0ddeefed3e4c030",
"name": "admin"
}
}
………………………………………………………………………………………………………………………………………………………………………………….
}
2) 通过keystone的命令, 获取nova的的public url地址
keystone --os-username admin --os-password passw0rd --os-tenant-name admin --os-auth-url http://127.0.0.1:5000/v2.0/ endpoint-list
3) 使用在第一步中获得的token, 和第二步中获得的nova public url, 放在命令行当中, 获取flaover列表
$ openstack --debug --os-url http://127.0.0.1:8774/v2/71c452812dc845e3a0ddeefed3e4c030 --os-token <PKIFormat Token> flavor list

DEBUG: openstackclient.shell clean_up ListFlavor
通过Token验证方式, 使用OpenStackClient
使用用户密码做验证的缺点是, 每次都需要传递用户密码到keystone 获得新的 token. 从性能角度考虑, 可以先获取一个 token, 然后在后续的REST中反复使用, 减少和keystone的交互. 这就是token验证方式.1) 先用curl命令, 直接与keystone交互, 获得一个PKI格式的 scope token
$ curl -s -X POST http://127.0.0.1:5000/v2.0/tokens -H "Content-Type: application/json" -H "User-Agent: python-keystoneclient" -d '{"auth":{"tenantName": "admin", "passwordCredentials":{"username": "admin", "password":"passw0rd"}}}' |
python-mjson.tool
# Partial Result
{
"token": {
"expires": "2014-08-12T09:35:52Z",
"id": "<PKI Format Token>",
"issued_at": "2014-08-12T08:35:52.154208",
"tenant": {
"description": null,
"enabled": true,
"id": "71c452812dc845e3a0ddeefed3e4c030",
"name": "admin"
}
}
………………………………………………………………………………………………………………………………………………………………………………….
}
2) 通过keystone的命令, 获取nova的的public url地址
keystone --os-username admin --os-password passw0rd --os-tenant-name admin --os-auth-url http://127.0.0.1:5000/v2.0/ endpoint-list
3) 使用在第一步中获得的token, 和第二步中获得的nova public url, 放在命令行当中, 获取flaover列表
$ openstack --debug --os-url http://127.0.0.1:8774/v2/71c452812dc845e3a0ddeefed3e4c030 --os-token <PKIFormat Token> flavor list
