Mistral Configuration Guide

Mistral configuration is needed for getting it work correctly either with real OpenStack environment or without OpenStack environment.

NOTE: The most of the following operations should performed in mistral directory.

Generate mistral.conf (if it does not already exist):

oslo-config-generator --config-file tools/config/config-generator.mistral.conf --output-file etc/mistral.conf

Edit file etc/mistral.conf.

If you are not using OpenStack, skip this item. Provide valid keystone auth properties:

[keystone_authtoken]
auth_uri = http://<Keystone-host>:5000/v3
identity_uri = http://<Keystone-host:35357/
auth_version = v3
admin_user = <user>
admin_password = <password>
admin_tenant_name = <tenant>

If you don't use OpenStack, provide auth_enable = False in config file:
```
[pecan]
auth_enable = False
```

If you are not using OpenStack, skip this item. Register Mistral service and Mistral endpoints on Keystone:

$ MISTRAL_URL="http://[host]:[port]/v2"
$ keystone service-create --name mistral --type workflowv2
$ keystone endpoint-create --service_id mistral --publicurl $MISTRAL_URL --adminurl $MISTRAL_URL --internalurl $MISTRAL_URL

Configure transport properties in the corresponding config section: for RabbitMQ it is oslo_messaging_rabbit:
```
[oslo_messaging_rabbit]
rabbit_userid = <user_id>
rabbit_password = <password>
rabbit_host = <host>
```

NOTE: Make sure that backend transport configuration is correct. Example for RabbitMQ:
[DEFAULT]
rpc_backend = rabbit

Configure database. SQLite can't be used in production. Use MySQL or PostgreSQL instead. Here are the steps how to connect MySQL DB to Mistral:

Make sure you have installed mysql-server package on your Database machine (it can be your Mistral machine as well).

Install MySQL driver for python:
pip install mysql-python
Create the database and grant privileges:
mysql -u root -p

CREATE DATABASE mistral;
USE mistral
GRANT ALL ON mistral.* TO 'root':<password>@<database-host>;
Configure connection in Mistral config:
[database]
connection = mysql://<user>:<password>@<database-host>:3306/mistral
NOTE: If PostgreSQL is used, configure connection item as below:
connection = postgresql://<user>:<password>@<database-host>:5432/mistral

If you are not using OpenStack, skip this item. Update mistral/actions/openstack/mapping.json file which contains all allowed OpenStack actions, according to the specific client versions of OpenStack projects in your deployment. Please find more detailed information in tools/get_action_list.py script.
Configure Task affinity feature if needed. It is needed for distinguishing either single task executor or one task executor from group of task executors:
```
[executor]
host = my_favorite_executor
```

Then, this executor can be referred in DSL by:
...Workflow YAML...
my_task:
  ...
  target: my_favorite_executor
...Workflow YAML...

After that try to run mistral engine and see it is running without any error:
```
mistral-server --config-file <path-to-config> --server engine
```
