Hi,
I'm trying to run a task on the servers of a role minus some hosts specified on
the commandline, but I just cannot get it to remember -x...
Here's my code:
------------------------------------------------------------------------------
import os
import paraproxy
from fabric.api import env, run, puts
EXCLUDE_FILE = '~/.hosts_excluded'
env.roledefs = {
'mailin' : [ 'x601', 'x602' ],
'mailout' : [ 'x603', 'x604' ],
}
env.roledefs['mail'] = env.roledefs['mailin']+env.roledefs['mailout']
def set_excludes(excludes=EXCLUDE_FILE):
with open(os.path.expanduser(excludes)) as fd:
env.exclude_hosts.extend([ host.strip() for host in fd.readlines() ])
puts("genrating hostlists...")
puts("Excludes from cli: %s" % ', '.join(env.exclude_hosts))
set_excludes()
puts("Excludes cli/file: %s" % ', '.join(env.exclude_hosts))
puts("... done")
def do_date():
run('date')
% /opt/python-2.7/bin/fab -f roles.py -R mail -x x601,x602 do_date
genrating hostlists...
Excludes from cli: x601, x602
Excludes cli/file: x601, x602, x204, x404, x203, x403, x25
... done
[x601] Executing task 'do_date'
[x601] run: date
[x601] out: Thu Aug 18 15:04:44 CEST 2011
[x601] out:
[x602] Executing task 'do_date'
[x602] run: date
[x602] out: Thu Aug 18 15:04:45 CEST 2011
[x602] out:
[x603] Executing task 'do_date'
[x603] run: date
[x603] out: Thu Aug 18 15:04:46 CEST 2011
[x603] out:
[x604] Executing task 'do_date'
[x604] run: date
[x604] out: Thu Aug 18 15:04:46 CEST 2011
[x604] out:
Done.
Doh, -x ignored...
It seems I don't completely get how and when hosts, exclude_hosts and roles are
mixed to pass on to a task.
And yes, I have read the manual.
Thanks in advance,
Sven
