Using Python Fabric without the command-line tool (fab)

Question

Altough Fabric documentations refers to a way of using the library for SSH access without requiring the fab command-line tool and/or tasks, I can\'t seem to manage a way to do i

Answer 1

Here are three different approaches all using the execute method

from fabric.api import env,run,execute,hosts

# 1 - Set the (global) host_string
env.host_string = "hamiltont@10.0.0.2"
def foo():
  run("ps")
execute(foo)

# 2 - Set host string using execute's host param
execute(foo, hosts=['hamiltont@10.0.0.2'])

# 3 - Annotate the function and call it using execute
@hosts('hamiltont@10.0.0.2')
def bar():
  run("ps -ef")
execute(bar)

For using keyfiles, you'll need to set either env.key or env.key_filename, as so:

env.key_filename = 'path/to/my/id_rsa'
# Now calls with execute will use this keyfile
execute(foo, hosts=['hamiltont@10.0.0.2'])

You can also supply multiple keyfiles and whichever one logs you into that host will be used
