Configure the overlay bundle¶
The deployment will make use of the
openstack-base bundle, which represents
the core of a Charmed OpenStack cloud. A separate overlay bundle is used to
tailor the configuration (possibly overriding settings in the bundle) so that
the deploy will work within a given environment.
Although it is possible to edit the bundle file itself, it is best practice to keep it pristine and to use an overlay instead.
Download overlay file
overlay-mymaas.yaml and save it in the
Replace the variables in the file with the some of the values that were collected in the previous step.
Once you’ve edited and saved the file, proceed to the Prepare Juju page.
The overlay file will require further adjustments as per the below scenarios.
$CONSTRAINTS with a null value (nothing) if constraints are not
Each principal charm will need to be informed of a network space, via the
bindings charm parameter, if a network space is configured within MAAS for
the cloud’s subnet.
OVN Chassis data port and hardware addresses¶
Comment out the
data-port variable if hardware addresses are being used to
designate the OVN Chassis interfaces:
#data-port: &data-port br-ex:$OVN_DATA_PORT
bridge-interface-mappings should then be configured in this
bridge-interface-mappings: >- br-ex:52:54:00:03:01:01 br-ex:52:54:00:03:01:02 br-ex:52:54:00:03:01:03
Use your own MAC addresses but preserve the
