Documents Ganeti version 2.0 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 support can also be enabled by passing command line parameters. The protocol used is JSON over HTTP designed after the REST principle. You can access the API using your favorite programming language as long as it supports network connections. wget -q -O - https://CLUSTERNAME:5080/2/info or curl https://CLUSTERNAME:5080/2/info import urllib2 f = urllib2.urlopen('https://CLUSTERNAME:5080/info') print f.read() 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/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); @INCLUDE_RAPI_RESOURCES@
