Configuration and Policy Guide

The static configuration for mistral lives in two main files: mistral.conf and policy.yaml. These are described below.

Configuration

Mistral, like most OpenStack projects, uses INI-style configuration files to configure various services and utilities. This functionality is provided by the oslo.config project. oslo.config supports loading configuration from both individual configuration files and a directory of configuration files. By default, mistral will search for a config file named /etc/mistral/mistral.conf.

More information on how you can use the configuration options to configure services and what configuration options are available can be found below.

Policy

Mistral, like most OpenStack projects, uses a policy language to restrict permissions on REST API actions. This functionality is provided by the oslo.policy project. oslo.policy supports loading policy configuration from both an individual configuration file, which defaults to policy.yaml, and one or more directories of configuration files, which defaults to policy.d. These must be located in the same directory as the mistral.conf file(s). This behavior can be overridden by setting the oslo_policy.policy_file and oslo_policy.policy_dirs configuration options.
