Example sshfs plugin and config for StarCluster

example_config

# This is an example config that assumes sshfs.py is either in 
# $HOME/.starcluster/plugins or lives somewhere in your $PYTHONPATH

[vol myvol]
volume_id = vol-99999
mount_path = /results

[plugin sshfs]
setup_class = sshfs.SSHFSPlugin
local_mount_path = ~/ec2-results
volume = myvol

[cluster default]
...
volumes = myvol
plugins = sshfs

sshfs.py

# Install this file to $HOME/.starcluster/plugins/sshfs.py or somewhere on your $PYTHONPATH
import os
from starcluster.clustersetup import ClusterSetup
from starcluster.logger import log

class SSHFSPlugin(ClusterSetup):
    def __init__(self, local_mount_path, volume):
        self.mount_path = os.path.expanduser(local_mount_path)
        self.volume = volume

    def run(self, nodes, master, user, user_shell, volumes):
        if not os.path.exists(self.mount_path):
            log.info("Creating mount path: %s" % self.mount_path)
            os.makedirs(self.mount_path)
        vol_path = volumes.get(self.volume).get('mount_path')
        ctx = dict(key=master.key_location, user=user, server=master.dns_name,
                   vol_path=vol_path, mount_path=self.mount_path)
        log.info("Mounting master:%s over sshfs" % vol_path)
        os.system('sshfs -o ssh_command="ssh -i %(key)s" '
                  '%(user)s@%(server)s:%(vol_path)s %(mount_path)s' % ctx)

I had to modify the last line in this script to the following to make it work:

os.system('sshfs -o ssh_command="ssh -i %(key)s" %(user)s@%(server)s:%(vol_path)s %(mount_path)s' % ctx)

@why-not Thanks, fixed.
