Tools for writing awesome Fabric files

About

fabtools includes useful functions to help you write your Fabric files.

fabtools makes it easier to manage system users, packages, databases, etc.

fabtools includes a number of low-level actions, as well as a higher level interface called fabtools.require.

Using fabtools.require allows you to use a more declarative style, similar to Chef or Puppet.

Installing

To install the latest release from PyPI

$ pip install fabtools

To install the latest development version from GitHub

$ pip install git+git://github.com/ronnix/fabtools.git

Example

Here is an example fabfile.py using fabtools

from fabric.api import *
from fabtools import require
import fabtools

@task
def setup():

    # Require some Debian/Ubuntu packages
    require.deb.packages([
        'imagemagick',
        'libxml2-dev',
    ])

    # Require a Python package
    with fabtools.python.virtualenv('/home/myuser/env'):
        require.python.package('pyramid')

    # Require an email server
    require.postfix.server('example.com')

    # Require a PostgreSQL server
    require.postgres.server()
    require.postgres.user('myuser', 's3cr3tp4ssw0rd')
    require.postgres.database('myappsdb', 'myuser')

    # Require a supervisor process for our app
    require.supervisor.process('myapp',
        command='/home/myuser/env/bin/gunicorn_paster /home/myuser/env/myapp/production.ini',
        directory='/home/myuser/env/myapp',
        user='myuser'
        )

    # Require an nginx server proxying to our app
    require.nginx.proxied_site('example.com',
        docroot='/home/myuser/env/myapp/myapp/public',
        proxy_url='http://127.0.0.1:8888'
        )

    # Setup a daily cron task
    fabtools.cron.add_daily('maintenance', 'myuser', 'my_script.py')

Supported targets

fabtools currently supports the following target operating systems:

• full support:
  • Debian family:
    • Debian 6 (squeeze), 7 (wheezy), 8 (jessie)
    • Ubuntu 10.04 (lucid), 12.04 (precise), 14.04 (trusty)
• partial support:
  • RedHat family:
    • RHEL 5/6
    • CentOS 5/6
    • Scientific Linux 5/6
    • Fedora
  • Arch Linux, Manjaro Linux
  • Gentoo
  • SmartOS (Joyent)

Contributions to help improve existing support and extend it to other Unix/Linux distributions are welcome!

fabtools's Issues

fabtools.postgres.user_exists() quick fix

For some reasons (gremlins ?) the test (res == "1") does not work even if the psql command returns "1"
I found it worked better using ("1" in res), without any str.strip(), etc...

Add timezone / localtime functions

It might be useful to add system.set_timezone, system.get_timezone and require.system.timezone functions. Currently, I'm using the following functions for my Ubuntu servers:

def set_timezone(timezone):
  run_as_root('echo "%s" > /etc/timezone' % timezone)
  run_as_root('dpkg-reconfigure --frontend noninteractive tzdata')
  require.service.restarted('cron')

def require_timezone(timezone):
  with settings(hide('commands'), warn_only=True):
    result = run('grep -q "^%s$" /etc/timezone' % timezone)
    ret_code = result.return_code
  if ret_code == 0:
    return
  elif ret_code == 1:
    set_timezone(timezone)
  else:
    raise SystemExit()

Of course it would need more to work on all supported distributions.

Automaticaly set use_sudo to False if I'm connected with root user

Hi,

If fabric is connected with "root" user, I need to use this code to install package :

require.deb.packages(['python-2.6', 'build-essential'], use_sudo=False)

I need to set "use_sudo=False".

I wonder if it's to possible in packages method to detect if I'm "root" user or not… and if I'm root user then use_sudo is set to False ?

Best regards,
Stephane

Vagrant boxes for functional tests

Fabtools Vagrant tests are really great but if we want to be compatible with listed systems we need to have set of base Vagrant boxes to run tests on.
I'm using some custom Ubutnu, Debian and CentOS boxes from http://www.vagrantbox.es/ now.
Can we do list of Vagrant boxes URL for each supported system?

I can start with ones that I'm using now:

• Ubuntu Lucid 32 - http://files.vagrantup.com/lucid32.box
• Debian Wheezy 64 - http://download.leap.se/leap-debian.box
• CentOS 6.3 32 - http://developer.nrel.gov/downloads/vagrant-boxes/CentOS-6.3-i386-v20130101.box
• CentOs 6.3 64 - http://developer.nrel.gov/downloads/vagrant-boxes/CentOS-6.3-x86_64-v20130101.box

API docs are currently broken on RTD.

The API docs pages on readthedocs.org currently show only the headline.

require.user => Documentation say « Sometimes we don't need a home directory » create_home=False is by default

I think there are an error here https://github.com/ronnix/fabtools/blob/master/fabtools/require/users.py#L24

You say « Sometimes we don't need a home directory » but create_home=False is by default.

I think default value must be True.

Is it implementation error or documentation error ?

Best regards,
Stephane

can't create a mysql user and a database

Hi,
I'm trying to use fabtools to create a user and a database under mysql with the following commands (in a Vagrant squeeze virtualbox):

require.mysql.server(password='root')
require.mysql.user('toto', password='toto')
require.mysql.database('toto', owner='toto')

Mysql is installed but I have the following error when trying to create user and database :

[localhost] out: Setting up mysql-server (5.1.66-0+squeeze1) ...
[localhost] out: 

[localhost] out: ERROR 1045 (28000): Access denied for user 'None'@'localhost' (using password: YES)

What did I got wrong ? I can see a lot of None values in the mysql commands.

started() for postgresql

Hi (bonjour en fait)

I always saw postgresql launch script installed in Ubuntu as /etc/init.d/postgresql, without any version number
Perhaps it's different in other distros ?

For now this line in fabtool/icanhaz/postgres.py server() function
started('postgresql-%s' % version)

throws an error, as expected :
Fatal error: sudo() encountered an error (return code 127) while executing '/etc/init.d/postgresql-8.4 start'

Example of virtualenv context manager.

This sounds really useful, could there be an example in the readme ?

Python 2.5 compatibility

Fabric supports Python 2.5, so we should too.

At least, we need to add some from __future__ import with_statement statements where we use with.

Is anything else needed?

OpenVZ tools don't work anymore

Hi ronnix,

Since the Fabric 1.5.0 release, Fabtools OpenVZ commands don't work anymore. It complains about not finding the quiet import from fabric.api . I'm ok to make a pull request for that but I don't know where to start. Could you point me what to do to solve this problem ?

Whatever thanks for fabtools which helps us a lot.

Frank

Postgresql installation.

Hello, i've got some issues using fabtools, could you please help me to solve it:

[[email protected]] sudo: sed -i.bak -r -e '/en_US.UTF-8\ UTF-8/ s/^([[:space:]]*)#[[:space:]]?/\1/g' "$(echo /etc/locale.gen)"

Aborting.

here's the code I try:
require.postgres.database(env.database_name, env.user)

Bash Tilde Expansion

I don't know if it's already known, but fabtools.require.directory("/foo"). That maps to running mkdir -p "/foo", and quoting the path to mkdir means that bash tilde expansion doesn't operate. Assuming you haven't specified a working path you end up with:

/home/myuser/~/foo

rather than

/home/myuser/foo

I don't know about anyone else, but a directory called ~ inside my home directory caused my brain to explode.

I don't know if it's worth considering switching to escaping spaces in paths, or maybe just updating the documentation to say not to use ~?

Note: fabtools.require.directory("$HOME/foo") is an easy work around once you know the problem exists.

Locale functions are broken in Ubuntu

Ubuntu uses /var/lib/locales/supported.d instead of /etc/locale.gen. This breaks fabtools locale functions and makes tests fail:

Templates?

Hi,

First - fabtools looks great. It's exactly what I'm looking for in terms of lightweight server configuration. In fact, I have a half-finished, broken version of the same idea sitting in a git repo somewhere.

However, it's not clear from the README how complete the project is at the moment. For example: the nginx example in the README passes a dictionary of data which is (I think) intended to be combined with a template (templates/nginx/sites/<server_name>.conf). But there's no information about how to create the templates and where to put them. It looks like the template location should be configurable, but as far as I can tell it isn't.

Sorry this issue is a bit vague - I used a specific problem (templates) to highlight a wider question. It'd be nice to know what to focus on when contributing to the project (assuming you're looking for contributions).

This should probably similar to supervisord support.

require.distro.package

How about this common function?

new file: fabtools/require/distro.py

from fabtools.require.deb import package as require_deb_package
from fabtools.require.rpm import package as require_rpm_package

def package(pkg_name, update=False, version=None):
    family = distrib_family()

    if family == 'debian':
        require_deb_package(pkg_name)

    elif family == 'redhat':
        require_rpm_package(pkg_name)

def packages()
    '...'

This can be used in require.python.setuptools()

    from fabtools.require.distro import packages as require_distro_packages
    if not is_setuptools_installed(python_cmd=python_cmd):
        require_distro_packages([
            'curl',
            'python-dev',
        ])

        install_setuptools(python_cmd=python_cmd)

I can send a pull request, if it is OK.

use_sudo keyword mean run_as_root

This is not the expected behaviour.

with settings(sudo_user='ronnix'):
    fabtools.require.directory('/tmp/foo', use_sudo=True)

if connected as root, it will create the directory as root instead of ronnix user.

sudo is not only used to gain root privileges. It can also be used to execute commands as another user.

0.9.3 is not usable

Trying to use it, or running the tests with tox, gives:

    import fabtools.group
ImportError: No module named group

Hi,
Is there a chance of a release? The main thing I'm after is the changes to postgres.py, since 0.4 on pypi.

hardcoded is_pip_installed parsing code

I am using pythonbrew to use multiple python version. I put pythonbrew script to my .profile, so I can run pythonbrew automatically when I logged in. However, fabtools is_pip_installed function in python.py has hardcoded pip version parsing, therefore it parses wrong.

For example,
When I execute pythonbrew it says
Switched to Python-2.7.3
Due to this output, is_pip_installed parse this string also by installed = res.split(' ')[1] raising following error.

ValueError: invalid version number 'to'

I think you should do more delicate parsing using regex.

def is_pip_installed(version=None, pip_cmd='pip'):
    """
    Check if `pip`_ is installed.

    .. _pip: http://www.pip-installer.org/
    """
    with settings(hide('running', 'warnings', 'stderr', 'stdout'), warn_only=True):
        res = run('%(pip_cmd)s --version 2>/dev/null' % locals())
        if res.failed:
            return False
        if version is None:
            return res.succeeded
        else:
            installed = res.split(' ')[1]
            if V(installed) < V(version):
                puts("pip %s found (version >= %s required)" % (installed, version))
                return False
            else:
                return True

Upstart support

Hi there,

Would you be willing to merge in patches to support upstart jobs? Sample API:

# fabtools.upstart
upstart.start('mysql')
upstart.restart('mysql')
upstart.stop('mysql')

# require.upstart
require.upstart.running('mysql')
require.upstart.stopped('mysql')

If the above API looks ok, I'll try to write a patch for this.

Require()ing a Postgres 9.2 server

I'd like to help out with supporting Postgres 9.2 installation on Ubuntu (there is no postgres-9.2 package for Ubuntu, and probably not on Debian either, but not sure). Right now, some solid packages are available here:

https://wiki.postgresql.org/wiki/Apt

.. and there's a shell script to add the appropriate APT repo here:

https://github.com/pgexperts/add-pgdg-apt-repo

What would be the best way to support requiring a Postgres 9.2 server if the installation process is more complicated than 'apt get update && apt-get install [postgres package name]' due to the local of the relevant APT repos?

Minor bug with fabtools.python.install

This code in python.py seems to assume that you can run python -m pip if you have python 2.7 or later. However, if you happen to have an older pip version installed -- for example pip 1.1 in a virtual environment -- that command will fail because pip doesn't have the appropriate pip.__main__ module.

version = _get_python_version(use_python).split('.')

if (int(version[0]) < 3) and (int(version[1]) < 7):
    command = 'pip-%s.%s' % (version[0], version[1])
else:
    command = '%(use_python)s -m pip' % locals()

command += ' install %(options)s %(packages)s' % locals()

$ python --version
Python 2.7.3
$ pip --version

$ python -m pip

Don't use os.path.join for remote paths

See: fabric/fabric#306

Fabric doesn't use os.path.join for remote paths, since this screws things up for clients that don't use '' as the local path separator (i.e. Windows)

(one place this shows up is in require.python.virtualenv)

Recommend that fabtools follows the same policy.

fabtools.cron is very basic

Even though the docstring for the module says that it's for managing crontab tasks you can't really manage tasks only add new files to /var/cron.d/

I've previously used buildout to add tasks to the user crontab and the recipe provides an interesting crontab manager:

http://svn.zope.org/z3c.recipe.usercrontab/trunk/src/z3c/recipe/usercrontab/usercrontab.py?view=markup

This manager allows you to add and remove tasks to an users cron file.

Do you think it's feasible to adapt this crontab manager to fabtools? Are you interested in extending the fabtools.cron module?

If there are several users with the same name but with different hosts then users_exists will report that user does not exist.

That's due to result of query. It contains more than one row and strict 'res == name' check fails.

Why the nginx.site first parameter is "server_name" and not "site_name" ?

require.postgres.database() references /etc/locale.gen

require.postgres.database references /etc/locale.gen which doesn't exist on my system. The only system I can find references is for Arch Linux.

I'd happily supply a patch but I'm not sure what file we need to watch on other systems.

Redis binds to 127.0.0.1

Initially the redis setup from fabtools did not work for me because it binds to 127.0.0.1 (fabtools / fabtools / require / redis.py). Changing it to 0.0.0.0 helped.

This post helped me fix it:
http://stackoverflow.com/questions/8537254/redis-connect-to-remote-server
(last answer)

Could you also change it to 0.0.0.0?

Kind regards,

make fabtools.python.virtualenv usable with local()

Because fabric's local function uses /bin/sh by default, rather than /bin/bash, the fabtools.python.virtualenv cannot be used with the local function.

You get something like this:
{{{
/bin/sh: source: not found
}}}

It would be really handy if the virtualenv context manager was usable locally as well.

I think this is as easy as changing the 'source' string to '.'

Alternately there could be a separate lvenv context manager.

Feedback when supervisord isn't able to start process

It would be nice if require.supervisor.process could raise an exception when supervisord is not able to start the process.

The lsb_release command is not available on some Debian VPS installs

Using fabtools.system.distrib_codename() doesn't seem to work on Debian wheezy, at least a stock install.

Fatal error: run() received nonzero return code 127 while executing!

Requested: lsb_release --codename --short
Executed: /bin/bash -l -c "lsb_release --codename --short"

=============================== Standard output ===============================

/bin/bash: lsb_release: command not found

Aborting.

I suggest that you use python -m pip ... and not pip ... to specify python version.
On my desktop, python -m pip --version working because I've python 2.7.

In vagrant VM, python -m pip --version didn't work because python 2.6 is installed.

I think that fabtools.python.install must work with python 2.6, then we can't use python -m pip syntax.
