A small webapp for viewing and searching Chef nodes
Project description
A small webapp for viewing Chef nodes and other metadata. Currently supports nodes, roles, and environments, as well as package version information (see below).
Usage
Run Sous-chef using Gunicorn:
gunicorn 'sous_chef:create_app()'
Configuration
Sous-chef will read it’s configuration from one of two places, depending on how it was installed:
# Global install /usr/var/sous_chef-instance/config.py # Virtualenv install $VIRTUALENV/var/sous_chef-instance/config.py
An example configuration file might look like this:
# The URL of the Chef server CHEF_URL = 'http://chef.example.com' # The client name and key to use CHEF_CLIENT = 'sous' CHEF_KEY = '/usr/var/sous_chef-instance/sous.pem'
If these are not set, PyChef’s autoconfigure function is used as a fallback, and will try and load it’s configuration from ~/.chef/knife.rb or /etc/chef/client.rb.
Package versions
Sous-chef will display package metadata from nodes if availible. It expects this data to be in the following format:
"packages": {
"<package_type>": {
"<package_name>": "<package_version",
...
},
...
}
For example, an RPM Ohai plugin could set the following node attributes:
"packages": {
"rpm": {
"package-one": "0.1.0",
"pacakge-two": "2.0.1"
}
}
Debug mode
The app can be run in debug mode by using the create_debug_app function:
gunicorn 'sous_chef:create_debug_app()'
The flask-debugtoolbar package is availible, the DebugToolbar extension will be used.
Installation
Install Sous-chef and Gunicorn with:
pip install 'sous-chef[deploy]'
Requirements
Requires Flask and PyChef. Gunicorn is the simplest method of deployment, but is not a requirement (allowing alternate WSGI servers to be used). Optionally uses Flask Debug Toolbar using the debug application.
Compatibility
Targets Python 2.6 and 2.7.
PyChef is currently Python 2 only, but if or when it is availible for Python 3 Sous-chef should have no problems.
