:alt: Latest Version
Mistral is a workflow service. Most business processes consist of multiple
distinct interconnected steps that need to be executed in a particular
order in a distributed environment. A user can describe such a process as a set
of tasks and their transitions. After that, it is possible to upload such a
description to Mistral, which will take care of state management, correct
execution order, parallelism, synchronization and high availability.
Mistral also provides flexible task scheduling so that it can run a process
according to a specified schedule (for example, every Sunday at 4.00pm) instead
of running it immediately. In Mistral terminology such a set of tasks and
relations between them is called a workflow.
Mistral client
==============
Python client for Mistral REST API. Includes python library for Mistral API and
Command Line Interface (CLI) library.
Installation
------------
First of all, clone the repo and go to the repo directory::
$ git clone git://git.openstack.org/openstack/python-mistralclient.git
$ cd python-mistralclient
Then just run::
$ pip install -e .
or::
$ pip install -r requirements.txt
$ python setup.py install
Running Mistral client
----------------------
If Mistral authentication is enabled, provide the information about OpenStack
auth to environment variables. Type::
$ export OS_AUTH_URL=http://<Keystone_host>:5000/v2.0
$ export OS_USERNAME=admin
$ export OS_TENANT_NAME=tenant
$ export OS_PASSWORD=secret
$ export OS_MISTRAL_URL=http://<Mistral host>:8989/v2 (optional, by
default URL=http://localhost:8989/v2)
and in the case that you are authenticating against keystone over https:
$ export OS_CACERT=<path_to_ca_cert>
.. note:: In client, we can use both Keystone auth versions - v2.0 and v3. But
server supports only v3.*
To make sure Mistral client works, type::
$ mistral workbook-list
You can see the list of available commands typing::
$ mistral --help
