Editor to share with you how to use ceph-rest-api, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

1. Version problem

Version 0.67-10.x if you need to integrate existing services, you can consider this built-in rest interface, which will be replaced by the built-in mgr module from 12.x and may be removed later, so do not use this interface in the higher version.

User management related operations create new users (keyring mode)

The first step is to create a new keyring for user client.user1, as follows

Root@demohost:/usr/lib/python2.7/dist-packages# cat / tmp/user1.keyring [client.user1] key = AQCtsihaEUozABAAPPDTEhSNJMkj4HOp+nJeaQ== caps mds = "allow" caps mon = "allow *" caps osd = "allow *"

The second step is to import users through rest-api

Root@demohost:/usr/lib/python2.7/dist-packages# curl http://0.0.0.0:5000/api/v0.1/auth/import-X PUT-T / tmp/user1.keyring

The third step is to view user information

Root@demohost:/usr/lib/python2.7/dist-packages# curl http://0.0.0.0:5000/api/v0.1/auth/get?entity=client.user1[client.user1] key = AQCtsihaEUozABAAPPDTEhSNJMkj4HOp+nJeaQ== caps mds = "allow" caps mon = "allow *" caps osd = "allow *"

View a list of users

Root@demohost:/usr/lib/python2.7/dist-packages# curl http://0.0.0.0:5000/api/v0.1/auth/listosd.0 key: AQDJ0adZpVCPIhAA8z/qYSPEX6Hn699piAS3bQ== caps: [mon] allow rwx caps: [osd] allow * osd.1 key: AQDK0adZNNGUMhAA06qcr+Dq59JmIZs1po/3uA== caps: [mon] allow rwx caps: [osd] allow * osd.2 key: AQDM0adZgcG6BhAA1s4yaZf323uGpuMazV3JXQ== caps: [mon] allow rwx caps: [osd] allow * client.user1 key: AQCtsihaEUozABAAPPDTEhSNJMkj4HOp+nJeaQ== caps: [mds] allow caps: [mon] allow * caps: [osd] allow * 5.
