Sometime ago I heard OpenSky deploys their app with fabric from @jwage, he had an article but I couldn’t make up the details since I was confused a bit by capifony. Now I know why they use it and here is the repo that we can improve together:
I improve this script from https://github.com/fabriceb/sfLive2011 and from jwage blog post http://jwage.com/post/31049115791/deploying-opensky-with-fabric which i did not remember but now that i look at it has some complementing things i will touch on the next part ii of this blog post.
Let’s install it from the mother ship https://github.com/cordoval/Symfony2Fabric:
pip install fabric
Let’s add fabfile.py to the root folder of our app:
from fabric.api import * from fabric.contrib.files import exists import os from time import strftime repo = 'git@github:username/mysite.git' path = '/var/www/mysite' env.use_ssh_config = True env.sudo_user = 'www-data' env.hosts = ['grace', 'gospel'] # check read-access to the keys, to be server-independent keys = ['~/.ssh/id_rsa'] env.key_filename = [key for key in keys if os.access(key, os.R_OK)] # this tags the sha deploy def tag_prod(): tag = "prod/%s" % strftime("%Y/%m-%d-%H-%M-%S") local('git tag -a %s -m "Prod"' % tag) local('git push --tags') def install(): sudo('mkdir -p ' + path) with cd(path): sudo('git clone ' + repo + ' .') sudo('composer install --dev') sudo('php app/console doctrine:database:create') sudo('php app/console doctrine:migrations:migrate --no-interaction') def update(): with cd(path): sudo('git remote update') sudo('git pull') sudo('composer install --dev') sudo('php app/console doctrine:migrations:migrate --no-interaction') # tag = run('git tag -l prod/* | sort | tail -n1') # run('git checkout ' + tag) def deploy(): if not exists(path): install() # tag_prod() update() #def rollback(num_revs=1): # with cd(path): # run('git fetch') # tag = run('git tag -l prod/* | sort | tail -n' + str(1 + int(num_revs)) + ' | head -n1') # run('git checkout ' + tag)
Thanks for your support, I hope to see you on Portland sflive! If you want to see me there please support me as it is very expensive :’(.
