Mistral

Task Orchestration and Scheduling service for OpenStack cloud

Installation

First of all, in a shell run:

tox

This will install necessary virtual environments and run all the project tests. Installing virtual environments may take significant time (~10-15 mins).

Before the first run

Before starting Mistral server, run sync_db script.

tools/sync_db.sh --config-file path_to_config*

Running Mistral API server

To run Mistral API server perform the following command in a shell:

tox -evenv -- python mistral/cmd/launch.py --server api --config-file path_to_config*

Note that an example configuration file can be found in etc/mistral.conf.sample.

Running Mistral Engines

To run Mistral Engine perform the following command in a shell:

tox -evenv -- python mistral/cmd/launch.py --server engine --config-file path_to_config*

Running Mistral Task Executors

To run Mistral Task Executor instance perform the following command in a shell:

tox -evenv -- python mistral/cmd/launch.py --server executor --config-file path_to_config

Note that at least one Engine instance and one Executor instance should be running so that workflow tasks are processed by Mistral.

Running Multiple Mistral Servers Under the Same Process

To run more than one server (API, Engine, or Task Executor) on the same process, perform the following command in a shell:

tox -evenv -- python mistral/cmd/launch.py --server api,engine --config-file path_to_config

The --server command line option can be a comma delimited list. The valid options are "all" (by default if not specified) or any combination of "api", "engine", and "executor". It's important to note that the "fake" transport for the rpc_backend defined in the config file should only be used if "all" the Mistral servers are launched on the same process. Otherwise, messages do not get delivered if the Mistral servers are launched on different processes because the "fake" transport is using an in process queue.

Debugging

To debug using a local engine and executor without dependencies such as RabbitMQ, create etc/mistral.conf with the following settings:

[DEFAULT]
rpc_backend = fake

[pecan]
auth_enable = False

and run in pdb, PyDev or PyCharm:

mistral/cmd/launch.py --server all --config-file etc/mistral.conf --use-debugger

Running examples

To run the examples find them in mistral-extra repository (https://github.com/stackforge/mistral-extra) and follow the instructions on each example.

Tests

Information about automated tests for Mistral can be found here: https://wiki.openstack.org/wiki/Mistral/Testing
