Compass Core Python Modules
compass/
is where all the core python modules of compass are, including API, DB, tasks and installers and so on.
##Direcotries and Files
* apiclient/ - API client.
* example.py - example code to deploy a cluster by calling compass API client.
* restful.py - compass API client library.
* v1/ - deprecated directory.
* api/ - API related files go here.
* api.py - defines compass RESTful API.
* api.raml - raml file to display/document compass RESTful api.
* auth_handler.py - handles API authentication.
* exception_handlers.py - handles API exceptions.
* utils.py - utilities for API.
* v1/ - deprecated directory.
* db/ - compass database modules.
* api/ - Database level API interfaces, which includes all compass primitive data types.
- This is the wrapper layer of the ORM tables and expose the useful logic of DB accessing.
* callback.py - metadata callback methods.
* config_validation/ - configuration validation module.
* exception.py - compass defined exceptions for database module.
* models.py - database model file, defining all compass database tables.
* validator.py - database validation methods.
* vi/ - deprecated directory.
* tasks/ - all celery tasks are defined here, and they asynchronously exercise functions in the ./actions directory.
* client.py - module to setup celery client.
* tasks.py - defines all celery tasks.
* actions/ - wrappers of heavy-lifting utility functions located in ./deployment,
./hdsdiscovery, ./log_analyzor
* health_check/ that does a health
check on compass and output diagnoses.
* deployment/ - backend deployment module that handles upstream data and dumps to installers
* deployment_manager.py - deployment dispatcher that defines interfaces and retrieves/updates configurations.
* installers - contains base installers and its children installers such as os_installer and pk_installer
(package_installer). These installers here are the "plugin" kind of files that interact with installer
tools(e.g. chef) that do the real installation tricks.
* utils/ - utility module that contains a constant.py which defines all keyword variables for deployment.
* hdsdiscovery/ - hardware discovery module, mainly for mac-address retrieval from switches.
* base.py - a base class that can be extended by vendors under vendor/ directory.
* error.py - hdsdiscovery module error handling.
* hdmanager.py - manages hdsdiscovery functionalities.
* SNMP_CONFIG.md - instructions on how to install and configure snmp related modules/packages.
* utils.py - contains utility functions for hdsdiscovery.
* vendors/ - switch/hardware vendor specific plugins. To support a new vendor:
1. Make sure the switch product supports SNMP.
2. Make sure the switch product uses standard MIB.
3. Add a corresponding plugin under vendors/.
using arista as an example, first a python file with the same name of its parent directory should be added
(e.g: arista.py). Define the class_name in the vendor file as "Arista" and give the class identical name.
Then create a subdirectory called "plugins" and place mac.py under it.
* log_analyzor/ - compass progress tracking module.
* adapter_matcher.py - module to provide installing progress calculation for the adapters.
* file_matcher.py - updates installing progresses by processing the log files.
* line_matcher.py - updates/gets progress when a matched line is found in log files.
* progress_calculator.py: provides functions to update installing progresses.
* utils/ - compass core module utility functions.
* tests/ - all unittest code
* test_serverside/ - tests for installers(now only supports chef).
