Re: [Fab-user] running parallel executions with different env.user

[Brandon Whaley]

Hi Stephen,

I'd probably take advantage of the fact that host strings in fabric can include the username using @ syntax: address@hidden

def deploy(release):

    deployables = init_deployables(release)

    # API kill first

    hosts = set(

        'address@hidden'.format(

            options['host'].upper(),

            options['host']

        ) for options in deployables.values()

    )

    kill_results = execute(apikill_apps, hosts=hosts)

    api_killed = any(kill_results.values())

    if api_killed:

        print "Sleeping 20 seconds to let apps shutdown before attempting to task kill remainders"

        sleep(20)

    # Cleanup everything remaining with taskkill

    execute(taskkill_apps, hosts=hosts)

Hello,

 

I’m looking to update a package that uses fabric to interact with a bunch of windows slaves (Cygwin sshd) to do things in parallel. Unfortunately I can’t work out how to have fabric use a different env.user for each host, because sadly the hosts require <machinename>+<username> as their login credentials.

 

For example how would I update this code to run things in parallel for each host?

 

deployables = init_deployables(release)

    # API kill first

    hosts = set([options['host'] for options in deployables.values()])

    api_killed = False

    for host in hosts:

        env.user = "{}+autobot".format(host.upper())

        api_killed = execute(apikill_apps, host=host)[host] or api_killed

 

    if api_killed:

        print "Sleeping 20 seconds to let apps shutdown before attempting to task kill remainders"

        sleep(20)

 

    # Cleanup everything remaining with taskkill

    for host in hosts:

        env.user = "{}+autobot".format(host.upper())

        execute(taskkill_apps, host=host)

 

Thanks!
