Как автоматизировать развертывание веб-сайта на производстве включая уменьшение CSS/JS?

В итоге я использовал Fabric и придумал сценарий, который делает именно то, что я хочу. Через 48 секунд все копируется во временный каталог, все файлы минимизируются, затем на сайте отображается «страница загрузки», все синхронизируется с сервером с помощью SSH, после чего снова запускается.

from fabric.api import *
import datetime

# Format the current date as string 20120908-221521 (8 Sep 2012, 22:15:21)
# This will be used to append to the folder of the deployment directory so there's a backup of what was deployed
currentDate = datetime.datetime.now().strftime("%Y%m%d-%H%M%S")

# Where the files for this deployment are stored
deploymentDir = "/var/www/deployments/mysite-deployment-" + currentDate

# SSH config for production server
env.use_ssh_config = True
env.hosts = ["mysite.net"]
env.user = "root"
env.port = 44

# Test connection to live server
def test():
  run("ls -al")

#--------------------------------------------------------------------------------------
# Main functions - to run use "fab live" from command line to update production server
#--------------------------------------------------------------------------------------
def live():
  backupToDeploymentDir()
  switchToProductionFiles()
  minifyCssAndJavaScript()
  switchToUpdatesInProgress()
  rsyncToProduction()
  switchToLive()  
  print("Deployment " + currentDate + " complete")

# Alias for the clearCachedFiles method - to run use "fab cc" or "fab live cc"
def cc():
  clearCachedFiles()
