Speaking only of the pacemaker C API, it's pretty low-level and unlikely to have anything of interest. The (meager) documentation for it is here: http://clusterlabs.org/pacemaker/doxygen/ There aren't any examples per se, but you can look at the various pacemaker command-line tools: https://github.com/ClusterLabs/pacemaker/tree/master/tools > > Thanks! > Vinod > > On Mon, Feb 4, 2019 at 8:57 AM Ken Gaillot <kgail...@redhat.com> > wrote: > > On Sun, 2019-02-03 at 08:44 -0800, Vinod Chegu wrote: > > > Hello, > > > > > > 'am new to this forum and am looking for some pointers. > > > > > > Are there any Python based examples (in some github repo etc) > > that > > > show the usage of Pacemaker/Corosync APIs for creation and > > management > > > (add/delete/list/[un]maintenance, monitor alerts) of cluster of > > Linux > > > nodes? > > > > > > Thanks ! > > > VC > > > > Hi Vinod, > > > > There is currently no Python API, though that is on the long-term > > wish > > list. > > > > Corosync and Pacemaker each have C APIs, but those are likely much > > lower level than you're interested in.
