devpi Cookbook

This cookbook installs and configures a devpi server. Devpi server is a PyPI-compatible Python Index server that acts as both a freestanding Python Index as well as a pull-through cache of the official Python Package Index.

Requirements

• Python Versions: Python 2.6 amd 2.7
• Operating Systems: Debian/Ubuntu, Enterprise Linux/CentOS

Attributes

Key	Type	Description	Default
['devpiserver']['admin_group']	String	This group can administer the devpi server. This group will be created if it does not exist.	devpi
['devpiserver']['server_root']	String	Store server data in this directory. This directory will be created if it does not exist.	/opt/devpi-server/data
['devpiserver']['server_port']	Integer	Port number that the server will listen on.	3141
['devpiserver']['daemon_user']	String	Expect the daemon to run as this user. This user will be created if it does not exist.	devpi
['devpiserver']['version']	String or nil	Install this version of the devpi-server package. Set this attribute to nil to install the latest version.	nil
['devpiserver']['virtualenv']	Path	Install Python virtual environment here	/opt/devpi-server

Usage

Add the devpi::server recipe to your run_list to install devpi server into a Python virtual environment created just for it. The devpi::nginx recipe creates an nginx site configured to expose the server on port 80.

The devpi::client recipe installs the devpi command line client into a virtual directory. The devpi::server recipe does not install the command line client so you have to apply this recipe if you want the client installed alongside the server.

devpi::server

Include this recipe in the run_list to install the devpi server. It will also create the daemon user and administrative group if necessary.

devpi::nginx

Include this recipe to expose the devpi-server using nginx as a front-end server.

devpi::client

Include this recipe to install the devpi command-line client. This will create a workstation from which you can manage a devpi-server installation.

devpi_server

This resource defines a complete installation of the devpi server. It will create the Python virtual environment, install the packages/users/groups needed to run the server, and even generate an nginx site definition for you.

Syntax

The simplest usage of the devpi_server resource is a single line that identifies where the server instance should be installed into:

devpi_server '/opt/devpi'

If you want to control more aspects of the installed server, you do so using the normal syntax:

devpi_server '/opt/devpi' do
  admin_group 'admins'
  port 6543
  nginx_site 'devpi'
end

Actions

Action	Description
:create	Default. Installs a new devpi server instance into the named directory.
:delete	Removes an existing server instance.

Attributes

Attribute	Description
directory	Install the devpi server into this directory. This will be used as the root of the Python virtual environment created for the server. If a virtual environment already exists, then it will be used as-is. This is the name attribute for this resource.
daemon_user	The user that will run the daemon. This is used to set the appropriate permissions on the data directories. The default value for this attribute is devpi.
admin_group	The user group responsible for managing the devpi server. This is used to set the appropriate permissions on the devpi related directories. The default value for this attribute is also devpi.
port	The port that the devpi server instance will listen on. The default value for this attribute is 3141.
data_directory	The directory used by the server to store the repository data. The default value for this attribute is a sub-directory of the server root named data.
nginx_site	If this attribute is set, then a new nginx site is created with the specified name. It will be configured as a front-end for the installed server.
version	If this attribute is set, then this version of the devpi package will be installed. If this is omitted or set to nil, then the most recent package will be installed.
replicate	If this attribute is set, then the server will be installed as a replica of the specified master URL. If this is omitted or set to nil, then the server will be installed as a master.

devpi_nginx_site

This resource uses the devpi-server command to generate an nginx site for the server and optionally enable it.

Syntax

The root directory of the server installation is the only required parameter.

devpi_nginx_site 'devpi' do
  directory '/opt/devpi'
end

This will create and enable an nginx site named devpi for the server that is installed in the /opt/devpi virtual environment.

Actions

Action	Description
:create	Generate and optionally install the nginx configuration.

Attributes

Attribute	Description
directory	Generate the site for the devpi server installed in this directory.
daemon_user	The user that will run the daemon. The default value for this attribute is devpi.
admin_group	The user group responsible for managing the devpi server. The default value for this attribute is devpi.
port	The port that the devpi server listens on. The default value for this attribute is 3141.
data_directory	The directory used by the server to store the repository data. The default value for this attribute is a sub-directory of the server root named data.
enable	Boolean flag that controls whether the site is enabled or not. By default, the site will be enabled.

Vagrantfile

Though not a usage of the cookbook per-se, the Vagrantfile can be used to start a stand-alone devpi-server instance. vagrant up will start the server and make it available at http://172.16.0.11/.

Contributing

1. Fork the repository on Github
2. Create a new branch from master to hold your changes.
3. Create the test kitchen environment by running kitchen converge on whichever suite you are targeting. Then run kitchen verify on the suite to make sure that the tests pass.
4. Edit README.md to describe your feature.
5. Write integration tests that verify your feature, run them with kitchen verify -- they should fail
6. Implement your feature in its default configuration. You should not modify anything outside if the recipe at this point. Keep iterating until the integration tests pass.
7. Run the static analysis tasks, rubocop and foodcritic, periodically. Fix any problems that they uncover.
8. Update README.md to mention any new attributes and add yourself to the AUTHORS list.
9. Issue a pull-request on Github.
