Django command to kill runserver. Handy when using Djanog in a docker container and using runserver externally.

kill_runserver.py

import os
import shlex
import subprocess
from subprocess import PIPE, STDOUT
from django.core.management.base import BaseCommand


class Command(BaseCommand):
    help = 'Kill local processes running runserver command'

    def handle(self, *args, **options):
        args = shlex.split('ps aux')
        p1 = subprocess.Popen(args, stdin=PIPE, stderr=STDOUT, stdout=PIPE)

        for line in p1.stdout:
            pid_parts = line.split(' ')
            
            for part in pid_parts:
                if part == 'runserver':
                    # print 'proc: ', line
                    # print 'kill %s' % pid_parts[7]
                    try:
                        int(pid_parts[7])  # check if pid is an int
                        status = os.system('kill %s' % pid_parts[7])
                        if status != 0:
                            print 'Kill FAILED'
                    except Exception as e:
                        print 'EXC: ', e
