OpenStack Glance Image-list 401

架設 OpenStack Juno ,安裝完 Glance 後進行測試時,glance 指令會一直出現 401 錯誤。

root@localhost:~# glance --debug image-list
curl -i -X GET -H 'User-Agent: python-glanceclient' -H 'Content-Type: application/octet-stream' -H 'Accept-Encoding: gzip, deflate, compress' -H 'Accept: */*' -H 'X-Auth-Token: ***'
Request returned failure status 401.
Invalid OpenStack Identity credentials.

查看 /var/log/glance/api.log 看到以下的錯誤訊息:

2015-04-08 15:34:03.127 18799 ERROR keystonemiddleware.auth_token [-] Bad response code while validating token: 403
2015-04-08 15:34:03.128 18799 WARNING keystonemiddleware.auth_token [-] Invalid user token. Keystone response: {u'error': {u'message': u'You are not authorized to perform the requested action: identity:validate_token', u'code': 403, u'title': u'Forbidden'}}

但是 keystone 指令本身沒問題:

root@localhost:~# keystone --debug token-get

Google 到了幾篇參考資料:

第一篇所提到 region 設定,不論是在 /etc/glance/glance-api.conf/etc/glance/glance-registry.conf 中設定 auth_region,還是在環境變數中設定 OS_REGION_NAME 都沒有效果。


Most of the services create the service user with the admin permission. This is unnecessary for token validation and they should be restricted to only having the service role.


Glance 的 user role 我本來設定是 Member,解決方法就是改成 admin role 問題就解決了
