I think --skip-bad-hosts would do the work.Try:fab DoTheUpdates --skip-bad-hosts -H <comma-separated list of hosts>Regards2015-09-16 1:52 GMT+02:00 Paul Hoffman <address@hidden>:_______________________________________________--Paul HoffmanHow can I get the above code to work? Or if this is too much of a kludge, what is the proper way to have DoTheUpdates try a bunch of hosts but gracefully stop each time it can't log into one?Greetings. I want a script to do an update to all of the hosts that are alive, but not spend time on ones that aren't. I tried the following as a way of filling env.hosts:
@hosts("address@hidden", "address@hidden")
def PickHosts():
PickAttempt = run("echo")
if PickAttempt.succeeded:
(env.hosts).append(env.host_string)
print("Adding {}".format(env.host_string))
PickHosts()
def DoTheUpdates(): ...However, running this with a command line of "fab DoTheUpdates", prompts:
No hosts found. Please specify (single) host string for connection:
