Overriding OpenStack Services Config

If you need to override any settings for any of the OpenStack services or add in additional configuration snippets, you can do so by defining additional mounts in your deploy repo.

For example if you wanted to add the following into neutron-server:

[mysection]
somevalue = 1

Firstly you would create either a Secret or a ConfigMap and ensure that it is being loaded by ${DEPLOY_NAME}/manifest/neutron/kustomize.yaml

Then you would edit ${DEPLOY_NAME}/helm-configs/neutron.yaml and add something like:

pod:
  mounts:
    neutron_server:
      neutron_server:
        volumeMounts:
          - mountPath: /etc/neutron/neutron.conf.d/myfile.conf  # file which will be loaded
            name: mysection  # volume name from below
            subPath: myfile.conf  # key in the Secret or ConfigMap from the volume below
            readOnly: true
        volumes:
          - name: mysection # volume name above
            secret:
              secretName: mysecret  # name of secret
