Initially the idea was to have for each cell export information
for the additional cell to deploy. The name of the new cell
is provided to the export command to create the export file
name, if not specified via --output-file.
Since the exported information is not in all cases specific to
the new cell and can be shared with multiple cells, it does
not make sense to have the new cell name as a required parameter.
Lets remove the name parameter is it is right now that the
export information file name is generic to be used for multiple
cells.

|
|
* 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 information file {output_file}
|
|
- other specific parameter files for the cell\n
