underwear 0.4.2

Dead simple LAMP-stack deployments for Python-powered web applications

Underwear is a library for easily deploying any Python-powered web application to one or more Linux servers.

What Problem Does Underwear Solve?

Despite the advent of configuration management tools such as Puppet, Chef, Ansible, and Salt, it remains difficult to deploy a web application because you have to first learn one of those tools and then write scripts in the tool’s domain-specific language.

Underwear makes deploying to a traditional Linux server stack as easy as deploying to Heroku by providing a pre-packaged, easily configurable library. Deployments can be executed simply by installing Underwear with pip, specifying the IP addresses of the server(s) to deploy to, then running a couple of commands.

Quick Start

After these ten steps your app should be completely configured, secured, and deployed to remote servers.

These instructions will be simplied in future releases as the library is further developed.

1. Install Underwear to your virtualenv:

   pip install underwear

2. Add ‘underwear’ to INSTALLED_APPS in your Django project. Underwear currently only supports Django (Flask and Bottle will be added in the 0.5 release).

3. Create a deploy directory under your Django project:

   mkdir deploy; cd deploy

4. Download the Fabric file for uploading SSH keys, YAML configuration template, and hosts file to your project under the deploy/ directory:

   wget https://raw.github.com/makaimc/underwear/master/underwear/deploy/fabfile.py
   wget https://raw.github.com/makaimc/underwear/master/underwear/deploy/underwear.yml
   wget https://raw.github.com/makaimc/underwear/master/underwear/deploy/hosts

5. Fill in blank variables fields in fabfile.py.

6. Execute the Fabric script (the script will prompt you for the non-root password):

   fab bootstrap_ansible

7. Fill in blank fields and modify desired settings in the underwear.yml file so that Underwear knows where to install your web application.

8. Fill in the hosts file with your servers’ IP addresses. For example, the file may look like the following:

   [webservers]
   192.168.1.1
   
   [dbservers]
   192.168.1.2

8. Deploy your application:

   python manage.py deploy

9. Underwear will output each step in the deployment process to standard output as it happens.

10. Access your application from the domain name you provided in the underwear.yml file.
