===========\n
|
|
* Create roles file for cell stack, e.g.:
|
|
openstack overcloud roles generate --roles-path \\
|
|
/usr/share/openstack-tripleo-heat-templates/roles \\
|
|
-o cell_roles_data.yaml Compute CellController
|
|
* Create new flavor used to tag the cell controller
|
|
* Tag cell controller nodes into the new flavor
|
|
* Create cell parameter file as explained in bellow doc link
|
|
* Deploy the cell and make sure to add the following information
|
|
to the deploy command:
|
|
- additional environment files used for overcloud stack
|
|
- --stack <cellname>
|
|
- cell role file created
|
|
- the exported cell input information file {output_file}
|
|
- other specific parameter files for the cell\n
