Disclaimer: Newb Python/Fabric user here.
I'm trying to use Fabric to deploy Karaf on a collection of servers. This
means I have to remotely connect to the same servers via SSH on two
different ports. The first SSH is into the server to retrieve and install
the packages for Karaf and the second SSH is into Karaf itself, which starts
on port 8101 by default. When I do so, using execute(), it works quite
well, but all actions after connecting to the second SSH port are executed
as the 'karaf' user on port 8101 rather than as the original user. This
forces me to have the Karaf connection be the very last thing I do before
disconnecting.
To illustrate, here's my simple example with sample output (hopefully)
demonstrating the hijacking of env.user
from fabric.api import env, run
from fabric.tasks import execute
env.hosts = ['192.168.5.250']
def firstSSH():
run("echo first")
executeHosts = []
for host in env.hosts:
executeHosts.append("notmmaley@" + host + ":8101")
execute(secondSSH, hosts=executeHosts)
run("echo first again")
def secondSSH():
run("echo second", shell=False, pty=False)
Sample output:
~/fabric$ fab firstSSH
[192.168.5.250] Executing task 'firstSSH'
[192.168.5.250] run: echo first
[192.168.5.250] Login password:
[192.168.5.250] out: first
[notmmaley@192.168.5.250:8101] Executing task 'secondSSH'
[notmmaley@192.168.5.250:8101] run: echo second
[notmmaley@192.168.5.250:8101] Login password:
[notmmaley@192.168.5.250:8101] out: second
[notmmaley@192.168.5.250:8101] run: echo first again
Done.
Disconnecting from 192.168.5.250:8101... done.
Disconnecting from mmaley@192.168.5.250... done.
I'd really like the tasks after the execute() to run as the original user
(mmaley). Am I doing something incorrectly, or is this a limitation of how
the context gets passed into/out of execute()?
Thanks in advance for any help/tutelage anyone can provide.
