Mistral Client / CLI Guide

Mistralclient installation

To install python-mistralclient, it is required to have pip (in most cases). Make sure that pip is installed. Then type:

pip install python-mistralclient

Or, if it is needed to install python-mistralclient from master branch, type:

pip install git+https://github.com/openstack/python-mistralclient.git

After python-mistralclient is installed you will see command mistral in your environment.

Configure authentication against Keystone

If Keystone is used for authentication in Mistral, then the environment should have auth variables:

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 when 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.

You can see the list of available commands by typing:
