這里freezer備份云硬盤實際上是調用了cinder-backup來實現的。

這里還要介紹下freezer依賴的幾個基本庫

freezer api底層的restful api框架是基于falcon實現的。falcon簡介：https://falconframework.org/

freezer scheduler基于APScheduler來實現定時備份的功能

具體實現見：https://github.com/yaoice/freezer-api/commit/4c3d371c28bc4635049bef4c037b7d1d36e9c532

使用curl測試api（freezer api使用keystone v2）

#?keystone?v2獲取token curl?-s?-d?'{"auth":{"passwordCredentials":{"username":?"admin", "password":?"cloud"},"tenantName":?"demo"}}'?-H?"Content-Type:?application/json"?http://192.168.141.6:5000/v2.0/tokens?|?python?-m?json.tool#?keystone?v3獲取token curl?-i???-H?"Content-Type:?application/json"???-d?' {?"auth":?{"identity":?{"methods":?["password"],"password":?{"user":?{"name":?"admin","domain":?{?"id":?"default"?},"password":?"cloud"}}}} }'???http://localhost:5000/v3/auth/tokens?;?echo#?獲取cinder所有的backups，純屬測試 curl?-s?-H?"X-Auth-Token:?fced5d5ae9e84009b3dca7972d7c5131"\?-X?GET\-H?"Content-type:?application/json"\?http://192.168.141.6:8776/v2/b232965aeb9c4b3a883ce41b16394e3f/backups?|?python?-m?json.tool#?freezer獲取backup?list curl?-s?-H?"X-Auth-Token:?fced5d5ae9e84009b3dca7972d7c5131"?-X?GET?-H?"Content-type:?application/json"?http://192.168.141.6:9090/v1/cinderbackups?|?python?-m?json.tool#?freezer創建backup???????? curl?-s?-H?"X-Auth-Token:?fd60f3b93b2841e893269b887572c26d"?-X?POST?-H?"Content-type:?application/json"?-d?'{"volume_id":?"438de34e-ef9e-4f4f-b047-600ab6229cc0"}'??http://192.168.141.6:9090/v1/cinderbackups#?freezer刪除backup curl?-s?-H?"X-Auth-Token:?76744b82dd8c49c490eb7c0ca5f33824"-X?DELETE-H?"Content-type:?application/json"http://192.168.141.6:9090/v1/cinderbackups/1ffe9901-43de-490e-b675-0bb92e50c4f4#?freezer還原備份，并創建一個新volume curl?-s?-H?"X-Auth-Token:?232685c229fd48d4b24629f7748bceda"?-X?POST?-H?"Content-type:?application/json"??http://192.168.141.6:9090/v1/cinderrestores/ed3e05bd-c892-441c-b9c6-226bbb030794#?freezer針對某個volume備份還原 curl?-s?-H?"X-Auth-Token:?232685c229fd48d4b2a629f7748bceda"-X?POST?-H?"Content-type:?application/json"?-d?'{"volume_id":?"496a7db9-3197-4658-9cc6-ef496f2b0cd1"}'??http://192.168.141.6:9090/v1/cinderrestores/da1b7290-5e56-43ff-b95f-a1c511b305d2
