Snapshot Python script with authtoken

Today i would like to show you, how you can easily create a Python script with openATTIC for automatic snapshot creation.

First of all we need a little Python script which can create snapshots for the specific openATTIC volume. This is really easy, because you can use the "API Recorder" within openATTIC. You just have to select an existing volume, click the record button (the little record symbol on the right topbar) and create a snapshot of that volume. Afterwards, you click the stop button (the record button switches into a stop button after you clicked it) and you will get a working Python script, containing the actual API calls.

Example:

#!/usr/bin/env python
import requests
import json
auth = ("username", "password") # edit username and password

headers = {'content-type': 'application/json'}

### recorded command 1
data=json.dumps({
    "volumeId": 615,
    "name": "2015-12-11-10-17-49",
    "megs": 4577
    })
requests.post("http://openattic.yourdomain.com/openattic/api/volumes/615/snapshots", auth=auth, data=data, headers=headers)

The only thing you have to change is the username/password and the name of the snapshot. Thats it.

If you don't want to use username/password in plaintext inside the Python script, you can use the openATTIC authtoken. To obtain your specific token you have to insert the following commands:

oaconfig dbshell
select * from authtoken_auth;

Example Output:

$ oaconfig dbshell
psql (9.4.2)
Type "help" for help.

openattic=# select * from auth
auth_group                         auth_permission_id_seq             auth_user_id_seq
auth_group_id_seq                  authtoken_token                    auth_user_user_permissions
auth_group_permissions             auth_user                          auth_user_user_permissions_id_seq
auth_group_permissions_id_seq      auth_user_groups
auth_permission                    auth_user_groups_id_seq
openattic=# select * from authtoken_token ;
key                    |            created            | user_id
-------------------------------------+-------------------------------+---------
 db2b68dd487bdfd24628ee07b814116acb2a228f | 2015-12-08 11:14:44.551939+01 |       1
(1 row)

Now you can change the authentication from user/pass to token. I also insert the current date and time for snapshotname creation:

#!/usr/bin/env python
import requests
import json
import datetime
token = "db2b68dd487bdfd24628ee07b814116acb2a228f"

headers = {'content-type': 'application/json',
           "Authorization": "Token %s" %token}

currentime = datetime.datetime.strftime(datetime.datetime.now(), '%Y-%m-%d %H:%M:%S')

### recorded command 1
data=json.dumps({
        "volumeId": 615,
        "name": currentime,
        "megs": 4577
                                                   })
requests.post("http://openattic.yourdomain.com/openattic/api/volumes/615/snapshots", data=data, headers=headers)

Thats it.
