A local client for interfacing to the WebFaction web hosting server API.
Project description
The WebFaction API client is a local client for interfacing to the WebFaction web hosting server API. It provides class-based organization, convenience methods, script execution, and HTML-formatted run reporting.
It can be used as standalone module to execute a supplied script file or as an imported library module within individual script files.
Detailed documentation is available on http://wf-api-client.readthedocs.org/en/latest/.

Let me know what you think of it…
What’s this all about?
WebFaction provides a perfectly cromulent RESTful API for their server accounts. It enables all aspects of server management to be executed remotely: CRUD actions for domains, websites, email, databases, etc. It even allows shell commands. Excellent!
This client extends that utility similarly to other IT automation solutions like Ansible, Salt, etc, by providing batching, parallelism, and reporting.
Class-based Organization
Functional groups are implemented as classes with API calls grouped as methods. Working with descriptive class instances makes complicated scripting easier, especially when driving more than one server or using more than one worker thread. In addition to atomic methods, batched convenience methods have been added, for e.g. creating/deleting RFC 2142 email prefixes in one call.
Convenience Methods
In addition to batch methods, convenience methods are used to speed script execution by performing client-side evaluation to avoid unnecessary remote API calls. Creation/deletion calls are compared against a single inventory call to ensure that entities exist before attempting deletion or do not exist before attempting creation. If not, client errors are reported.
Script Execution
Why have an API if it’s not being scripted against? The client provides scripting two ways: Scripts can be passed directly to the client in a standalone module call, or the module can be imported as a library module within standalone scripts. See below for examples of both approaches.
HTML-formatted Run Reporting
Since RESTful services are stateless, they can’t (shouldn’t) provide history. This client does. Every method call resulting in a remote API call returns the status, datetime, API call name, and call result to a log function. The running tally of logged actions are collected and reported as a HTMl report file. Call results are color-coded green for ‘success’ and red for ‘failure’. Elementary!
Examples
Standalone module calls are invoked like this:
python `wfapiclient.py` "username" "password" --scriptfile=/home/user/scripts/create_emails --reportfile=/tmp/create_emails.html
A standalone script calls methods directly using Python syntax. The run report is automatically generated for a supplied file name. Standalone scripts are structured like this:
"""`create_emails` script""" email = Email() email.create_emails(domain="example.com", targets="user@example.com") #EOF - `create_emails`
Standalone scripts import the module as a library and are responsible for instantiating the Runner class to log results and write out the run report. It is more flexible in that multiple runner objects can be created to work on different servers at one time logging either to separate reports or to one shared report. Standalone scripts are structured like this:
"""`create_emails` script""" import wfapiclient as wf runner1 = Runner() runner2 = Runner() #WebFaction automagically identifies target server by username/password. runner1.login_to_server("first_username", "first_password") runner2.login_to_server("second_username", "second_password") #Server objects are tied to runner instances for call execution and logging. email1 = Email(runner1) email1.create_emails(domain="first.example.com", targets="user1@first.example.com") email2 = Email(runner2) email2.create_emails(domain="second.example.com", targets="user2@second.example.com") #Either write report to separate report files... runner1.write_report_to_file("/tmp/create_emails1.html") runner2.write_report_to_file("/tmp/create_emails2.html") #...or write (append) reports to one shared file. runner1.write_report_to_file("/tmp/create_emails_shared.html") runner2.write_report_to_file("/tmp/create_emails_shared.html") #EOF - `create_emails`
Enjoy.
