Mistral Client Library
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.

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>
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
