mistral/contrib/devstack

1. Follow Devstack documentation to setup a host for Devstack. Then clone Devstack source code:

   $ git clone https://github.com/openstack-dev/devstack

2. Clone Mistral source code:

   $ git clone https://github.com/openstack/mistral

3. Copy Mistral integration scripts to Devstack:

   $ cp mistral/contrib/devstack/lib/mistral ${DEVSTACK_DIR}/lib
   $ cp mistral/contrib/devstack/extras.d/70-mistral.sh ${DEVSTACK_DIR}/extras.d/

4. Create/modify a localrc file as input to devstack:

   $ cd devstack
   $ touch localrc

5. The Mistral service is not enabled by default, so it must be enabled in localrc before running stack.sh. This example of localrc file shows all of the settings required for Mistral:

   # Enable Mistral
   enable_service mistral

6. Deploy your OpenStack Cloud with Mistral:

   $ ./stack.sh

Note:

1. All needed keystone endpoints for Mistral will be automatically created during installation.
2. Python-mistralclient will be also cloned and installed automatically.
