    scaling up neutron-gateway charm(?)

    Hi all,
    I am sorry if this question sound silly, but I am so curious.
    I already deployed openstack queen using juju on to 10 machines. I used openstack base bundle as initial configuration and modified it for HA purpose
    Machine configuration as follow:
    3 machines as storage (ceph backed)
    3 machines as compute
    3 machines as controller and configured as HA clustered
    1 machine as network node. Neutron-API and Neutron-gateway deployed into it.
    If I want to configure this network node as HA clustered, Should I scale up neutron-gateway app or no? There is no text in it's reference about scaling-up. One more thing there is no vip config in this charm.
    Thank you

    Any news here? I have the same question. Here is a info: https://jujucharms.com/openstack-base/

    Neutron Gateway, Nova Compute and Ceph services are designed to be horizontally scalable.

    To horizontally scale Neutron Gateway:

    juju add-unit neutron-gateway # Add one more unit
    juju add-unit -n2 neutron-gateway # Add 2 more unitsa
    Maybe this is all to do for scaling neutron-gateway charm as ha-cluster... but I do not know if there is anything else to consider.

    thank you for your response. you are right that is all to do to scale neutron-gateway horizontally and seems nothing else. I already did those thing and tested by shutting down one of neutron-gateway and seems cluster still works well.

    sounds good... did you use the ha-cluster charm https://jujucharms.com/hacluster/ ? Or only a new neutron-gateway charm?
    Have you configured other things in the neutron-gateway charm like interfaces or ip?

    I used only neutron-gateway charm, that's all, nothing fancy to be setup

    oh forgot one thing, I deployed neutron-gateway charm directly on to root machine and config as follow:
    juju config neutron-gateway bridge-mappings='physnet1:br-ex'
    juju config neutron-gateway data-port=br-ex:eno2
    juju config neutron-gateway ha-bindiface=eno1

    of course interface name have to follow yours
