8 | 4352bf6d | Iustin Pop | Introduction |
9 | 4352bf6d | Iustin Pop | ------------ |
10 | 4352bf6d | Iustin Pop | |
11 | 4352bf6d | Iustin Pop | Ganeti supports a remote API for enable external tools to easily |
12 | 4352bf6d | Iustin Pop | retrieve information about a cluster's state. The remote API daemon, |
13 | 4352bf6d | Iustin Pop | *ganeti-rapi*, is automatically started on the master node. By default |
14 | 4352bf6d | Iustin Pop | it runs on TCP port 5080, but this can be changed either in |
15 | 4352bf6d | Iustin Pop | ``.../constants.py`` or via the command line parameter *-p*. SSL mode, |
16 | 4352bf6d | Iustin Pop | which is used by default, can also be disabled by passing command line |
17 | 4352bf6d | Iustin Pop | parameters. |
18 | 4352bf6d | Iustin Pop | |
19 | 4352bf6d | Iustin Pop | Protocol |
20 | 4352bf6d | Iustin Pop | -------- |
21 | 4352bf6d | Iustin Pop | |
22 | 4352bf6d | Iustin Pop | The protocol used is JSON_ over HTTP designed after the REST_ |
23 | 4352bf6d | Iustin Pop | principle. |
24 | 4352bf6d | Iustin Pop | |
25 | 4352bf6d | Iustin Pop | .. _JSON: http://www.json.org/ |
26 | 4352bf6d | Iustin Pop | .. _REST: http://en.wikipedia.org/wiki/Representational_State_Transfer |

28 | 2cad4b91 | Iustin Pop | Generic parameters |
29 | 2cad4b91 | Iustin Pop | ------------------ |
30 | 2cad4b91 | Iustin Pop | |
31 | 2cad4b91 | Iustin Pop | A few parameter mean the same thing across all resources which implement it. |
32 | 2cad4b91 | Iustin Pop | |
33 | 2cad4b91 | Iustin Pop | ``bulk`` |
34 | 2cad4b91 | Iustin Pop | ++++++++ |
35 | 2cad4b91 | Iustin Pop | |
36 | 2cad4b91 | Iustin Pop | Bulk-mode means that for the resources which usually return just a |
37 | 2cad4b91 | Iustin Pop | list of child resources (e.g. ``/2/instances`` which returns just |
38 | 2cad4b91 | Iustin Pop | instance names), the output will instead contain detailed data for all |
39 | 2cad4b91 | Iustin Pop | these subresources. This is more efficient than query-ing the |
40 | 2cad4b91 | Iustin Pop | sub-resources themselves. |
41 | 2cad4b91 | Iustin Pop | |
42 | 2cad4b91 | Iustin Pop | ``dry-run`` |
43 | 2cad4b91 | Iustin Pop | +++++++++++ |
44 | 2cad4b91 | Iustin Pop | |
45 | 2cad4b91 | Iustin Pop | The optional *dry-run* argument, if provided and set to a positive |
46 | 2cad4b91 | Iustin Pop | integer value (e.g. ``?dry-run=1``), signals to Ganeti that the job |
47 | 2cad4b91 | Iustin Pop | should not be executed, only the pre-execution checks will be done. |
48 | 2cad4b91 | Iustin Pop | |
49 | 2cad4b91 | Iustin Pop | This is useful in trying to determine (without guarantees though, as |
50 | 2cad4b91 | Iustin Pop | in the meantime the cluster state could have changed) if the operation |
51 | 2cad4b91 | Iustin Pop | is likely to succeed or at least start executing. |
52 | 2cad4b91 | Iustin Pop | |
53 | 3427d34f | Michael Hanselmann | ``force`` |
54 | 3427d34f | Michael Hanselmann | +++++++++++ |
55 | 3427d34f | Michael Hanselmann | |
56 | 3427d34f | Michael Hanselmann | Force operation to continue even if it will cause the cluster to become |
57 | 3427d34f | Michael Hanselmann | inconsistent (e.g. because there are not enough master candidates). |
