Requirements

• python 2.6 or later

• fabric

How to Use

0. install

   % pip install envassert

1. write fabfile.py.

   from fabric.api import env, task
   from envassert import file, process, package, user, group, port, cron, detect
   
   env.use_ssh_config = True
   
   @task
   def check():
       env.platform_family = detect.detect()
   
       assert file.exists("/etc/hosts")
       assert file.is_file("/etc/hosts")
       assert file.is_dir("/tmp/")
       assert file.dir_exists("/tmp/")
       assert file.has_line("/etc/passwd", "sshd")
       assert file.owner_is("/bin/sh", "root")
       assert file.group_is("/bin/sh", "root")
       assert file.mode_is("/bin/sh", "777")
   
       if env.platform_family == "freebsd":
           assert file.is_link("/compat")
       else:
           assert file.is_link("/usr/tmp")
   
       assert package.installed("wget.x86_64")
   
       assert user.exists("sshd")
       assert user.is_belonging_group("shirou", "users")
       assert group.exists("wheel")
   
       assert port.is_listening(22)
       assert port.is_listening(80, "tcp")
   
       assert process.is_up("http") is False
       assert service.is_enabled("httpd")
   
       assert cron.has_entry('shirou', 'python')
   
       assert filesystem.is_type('ext4', '/')

2. run fab

   % fab -H somehost check
   [somehost] Executing task 'check'
   
   Done.
   Disconnecting from root@192.168.22.98... done.

   You can use any other fabric arguments like hosts or parallel.

Detecting OS

The detect.detect() function can detect target OS and distribution. Setting this variable to env.platform_family, functions can dispatch according to that value.

This function is a minimal port of ohai.

Currently, these platform can be detected. (but not tested yet)

• rhel (redhat, centos, oracle, scientific, enterpriseenterprise, amazon)

• debian (debian, ubuntu, linuxmint, raspbian)

• fedora

• suse

• gentoo

• arch

• freebsd

• netbsd

• openbsd

• darwin

However, every functions are not implemented for these all platform. Pull Requests are welcome.
