DriverLog
Contents
Mission
The DriverLog project is on a mission to provide information about drivers and plugins developed for both OpenStack itself and projects related to OpenStack. When it comes to a production OpenStack deployment a customer wants to have an assurance that certain hardware/virtual appliances will really work with certain OpenStack components. The DriverLog project aimed at enabling potential users/developers to quickly determine if a particular vendor driver exists and has been tested for a particular OpenStack release.
Target audience
Vendors
- Readily available, community supported driver marketplace.
- One common and measurable version of the truth with regards to vendor driver compatibility with OpenStack releases.
OpenStack customers
- Standardized information OpenStack users can use and trust.
- Improved quality and reliability of OpenStack.
OpenStack Community
- Encourage more participation of vendors in the community.
- Meet the quality, reliability and openness expected by OpenStack users.
- Accelerate OpenStack mission of building a universal, open fabric for an heterogeneous set of components while avoiding component fragmentation and non-operable point products.
Description
DriverLog is a service that collects and processes information about OpenStack drivers, their maintainers, availability in trunk, CI testing status and makes it possible to visualize it in a convenient web dashboard. The Driver dashboard makes it possible to view data by project, vendor and other factors.
Tracked projects
DriverLog stores a list of projects and their drivers in the configuration file default_data.json. Any contributor can add an untracked project. The projects section represents the list of tracked projects. It has the following format:
"projects": [ { "id": "openstack/cinder", "name": "Cinder (Block Storage)" }, { "id": "openstack/neutron", "name": "Neutron (Networking)" }, { "id": "openstack/nova", "name": "Nova (Compute)" }, { "id": "openstack/sahara", "name": "Sahara (Data Processing)" } ],
Tracked releases
The releases section represents the list of OpenStack releases. It has the following format:
"releases": [ { "id": "austin", "wiki": "https://wiki.openstack.org/wiki/ReleaseNotes/Austin" }, { "id": "bexar", "wiki": "https://wiki.openstack.org/wiki/ReleaseNotes/Bexar" }, { "id": "cactus", "wiki": "https://wiki.openstack.org/wiki/ReleaseNotes/Cactus" }, { "id": "diablo", "wiki": "https://wiki.openstack.org/wiki/ReleaseNotes/Diablo" }, { "id": "essex", "wiki": "https://wiki.openstack.org/wiki/ReleaseNotes/Essex" }, { "id": "folsom", "wiki": "https://wiki.openstack.org/wiki/ReleaseNotes/Folsom" }, { "id": "grizzly", "wiki": "https://wiki.openstack.org/wiki/ReleaseNotes/Grizzly" }, { "id": "havana", "wiki": "https://wiki.openstack.org/wiki/ReleaseNotes/Havana" }, { "id": "icehouse", "wiki": "https://wiki.openstack.org/wiki/ReleaseNotes/Icehouse" }, { "id": "juno", "wiki": "https://wiki.openstack.org/wiki/Releases" } ],
Tracked drivers
Any contributor can add an untracked driver. The drivers section represents the list of tracked drivers . It has the following format:
{ "project_id": "openstack/cinder", "vendor": "EMC", "name": "SMI-S (FC)", "descroption": "Fiber-channel driver", "maintainer": { "name": "Xing Yang", "email": "xing.yang@emc.com" }, "wiki": "http://wiki.openstack.org/", "releases": ["Icehouse"], "ci_id": "my_jenkins" },
For each driver the following parameters may be specified:
- project_id - OpenStack project (mandatory)
- vendor - Driver vendor (mandatory)
- name - Driver name (mandatory)
- description - driver description
- maintainer - information about driver maintainer, including name, email, irc id
- wiki - link to the OpenStack wiki page with driver setup instructions
- releases - a list of OpenStack releases the driver supported in
- ci_id - Gerrit id of external CI
How To’s
Add a new driver to DriverLog
- A vendor wants to add a new driver.
- A vendor adds a new driver section to the DriverLog JSON file.
{ "project_id": "openstack/neutron", "vendor": "Extreme Networks", "name": "Neutron Plugin", "wiki": "http://extrcdn.extremenetworks.com/wp-content/uploads/2014/02/SDN_OpenStack_Install_Guide_Final1.pdf", "releases": ["Icehouse"] }
- Records in config file should be sorted by key - (project_id, vendor). The configuration file automatically validated against the config file scheme.
- A project DriverLog Core Engineer receives a request to review a commit.
- An DriverLog Core Engineer makes a review. If everything is ok an DriverLog Core Engineer merges an update.
- A driver is getting displayed in the Drivers list on the DriverLog Dashboard. ‘CI tested’ column will show cross mark meaning that CI is not present. 'In trunk' column will show a list of releases specified in field 'releases'.
External CI verification
- Vendor can deploy an external voting CI environment that runs automatic tests against a driver on every commit. Instructions for setting up external CI can be found here:
In order to config DriverLog to poll external CI for current verification status field 'ci_id' needs to be provided. 'ci_id' is Gerrit Id of external CI, see example below:
{ "project_id": "openstack/neutron", "vendor": "Embrane", "name": "Neutron Plugin", "maintainer": { "name": "Ivar Lazzaro", "irc": "ivar-lazzaro" }, "wiki": "https://wiki.openstack.org/wiki/Neutron/EmbraneNeutronPlugin", "ci_id": "eci" },
- A vendor submits a patch.
- A DriverLog Core Engineer makes a review. If everything is ok he/she merges an update.
- The actual results of driver testing are stored in Gerrit. The backend runs as a scheduled background butch performing the following logic every 4 hours:
- The DriverLog backend by using CI environment ID (ci_id) recognizes which Gerrit reviews are related to this driver.
- The backend parses all merged patches from new to old.
- For every review it checks ci_id and branch (version).
- If pair ci_id+branch appears for the first time, then the backend stores the pair with test run result and link
Note: Only known ci_id’s from default_data.json are processed by the backend.
Release Notes
Release 0.1
- Nova, Cinder, Neutron and Sahara projects included into DriverLog.
- Information about supported drivers from projects’ wiki pages was manually converted into JSON config file:
