1. Follow Devstack documentation to setup a host for Devstack. Then clone
|
||||
Devstack source code.
|
||||
|
||||
2. Copy Mistral integration scripts to Devstack::
|
||||
|
||||
$ cp lib/mistral ${DEVSTACK_DIR}/lib
|
||||
$ cp extras.d/70-mistral.sh ${DEVSTACK_DIR}/extras.d
|
||||
|
||||
3. Create a ``localrc`` file as input to devstack.
|
||||
|
||||
4. The Mistral service is not enabled by default, so it must be
|
||||
enabled in ``localrc`` before running ``stack.sh``. This example ``localrc``
|
||||
file shows all of the settings required for Mistral::
|
||||
|
||||
# Enable Mistral
|
||||
enable_service mistral
|
||||
|
||||
5. Deploy your OpenStack Cloud with Mistral::
|
||||
|
||||
$ ./stack.sh
