Documents Ganeti version 2.17
Contents
Ganeti supports a remote API for enable external tools to easily retrieve information about a cluster’s state. The remote API daemon, ganeti-rapi, is automatically started on the master node. By default it runs on TCP port 5080, but this can be changed either in .../constants.py or via the command line parameter -p. SSL mode, which is used by default, can also be disabled by passing command line parameters.
ganeti-rapi reads users and passwords from a file (usually /var/lib/ganeti/rapi/users) on startup. Changes to the file will be read automatically.
Lines starting with the hash sign (#) are treated as comments. Each line consists of two or three fields separated by whitespace. The first two fields are for username and password. The third field is optional and can be used to specify per-user options (separated by comma without spaces).
Passwords can either be written in clear text or as a hash. Clear text passwords may not start with an opening brace ({) or they must be prefixed with {cleartext}. To use the hashed form, get the MD5 hash of the string $username:Ganeti Remote API:$password (e.g. echo -n 'jack:Ganeti Remote API:abc123' | openssl md5) [1] and prefix it with {ha1}. Using the scheme prefix for all passwords is recommended. Scheme prefixes are case insensitive.
Options control a user’s access permissions. The section Access permissions lists the permissions required for each resource. If the --require-authentication command line option is given to the ganeti-rapi daemon, all requests require authentication. Available options:
Example:
# Give Jack and Fred read-only access
jack abc123
fred {cleartext}foo555
# Give write access to an imaginary instance creation script
autocreator xyz789 write
# Hashed password for Jessica
jessica {HA1}7046452df2cbb530877058712cf17bd4 write
# Monitoring can query for values
monitoring {HA1}ec018ffe72b8e75bb4d508ed5b6d079c read
# A user who can read and write (the former is implied by granting
# write access)
superuser {HA1}ec018ffe72b8e75bb4d508ed5b6d079c read,write
When using the RAPI, username and password can be sent to the server by using the standard HTTP basic access authentication. This means that for accessing the protected URL https://cluster.example.com/resource, the address https://username:password@cluster.example.com/resource should be used instead. Alternatively, the appropriate parameter of your HTTP client (such as -u for curl) can be used.
| [1] | Using the MD5 hash of username, realm and password is described in RFC 2617 (“HTTP Authentication”), sections 3.2.2.2 and 3.3. The reason for using it over another algorithm is forward compatibility. If ganeti-rapi were to implement HTTP Digest authentication in the future, the same hash could be used. In the current version ganeti-rapi‘s realm, Ganeti Remote API, can only be changed by modifying the source code. |
The protocol used is JSON over HTTP designed after the REST principle. HTTP Basic authentication as per RFC 2617 is supported.
HTTP requests with a body (e.g. PUT or POST) require the request header Content-type be set to application/json (see RFC 2616 (HTTP/1.1), section 7.2.1).
JSON as used by Ganeti RAPI does not conform to the specification in RFC 4627. Section 2 defines a JSON text to be either an object ({"key": "value", …}) or an array ([1, 2, 3, …]). In violation of this RAPI uses plain strings ("master-candidate", "1234") for some requests or responses. Changing this now would likely break existing clients and cause a lot of trouble.
Unlike Python’s JSON encoder and decoder, other programming languages or libraries may only provide a strict implementation, not allowing plain values. For those, responses can usually be wrapped in an array whose first element is then used, e.g. the response "1234" becomes ["1234"]. This works equally well for more complex values. Example in Ruby:
require "json"
# Insert code to get response here
response = "\"1234\""
decoded = JSON.parse("[#{response}]").first
Short of modifying the encoder to allow encoding to a less strict format, requests will have to be formatted by hand. Newer RAPI requests already use a dictionary as their input data and shouldn’t cause any problems.
According to RFC 2616 the main difference between PUT and POST is that POST can create new resources but PUT can only create the resource the URI was pointing to on the PUT request.
Unfortunately, due to historic reasons, the Ganeti RAPI library is not consistent with this usage, so just use the methods as documented below for each resource.
For more details have a look in the source code at lib/rapi/rlib2.py.
A few generic refered parameter types and the values they allow.
A few parameter mean the same thing across all resources which implement it.
Bulk-mode means that for the resources which usually return just a list of child resources (e.g. /2/instances which returns just instance names), the output will instead contain detailed data for all these subresources. This is more efficient than query-ing the sub-resources themselves.
The boolean dry-run argument, if provided and set, signals to Ganeti that the job should not be executed, only the pre-execution checks will be done.
This is useful in trying to determine (without guarantees though, as in the meantime the cluster state could have changed) if the operation is likely to succeed or at least start executing.
Some parameters are not straight forward, so we describe them in details here.
The instance policy specification is a dict with the following fields:
A list of dictionaries, each with the following two fields:
A sub- dict with the following fields, which sets the limit of the instances:
You can access the API using your favorite programming language as long as it supports network connections.
Ganeti includes a standalone RAPI client, lib/rapi/client.py.
Using wget:
$ wget -q -O - https://CLUSTERNAME:5080/2/info
or curl:
$ curl https://CLUSTERNAME:5080/2/info
Note: with curl, the request method (GET, POST, PUT) can be specified using the -X command line option, and the username/password can be specified with the -u option. In case of POST requests with a body, the Content-Type can be set to JSON (as per the Protocol section) using the parameter -H "Content-Type: application/json".
Warning
While it’s possible to use JavaScript, it poses several potential problems, including browser blocking request due to non-standard ports or different domain names. Fetching the data on the webserver is easier.
var url = 'https://CLUSTERNAME:5080/2/info';
var info;
var xmlreq = new XMLHttpRequest();
xmlreq.onreadystatechange = function () {
if (xmlreq.readyState != 4) return;
if (xmlreq.status == 200) {
info = eval("(" + xmlreq.responseText + ")");
alert(info);
} else {
alert('Error fetching cluster info');
}
xmlreq = null;
};
xmlreq.open('GET', url, true);
xmlreq.send(null);
