I am going to deploy keystone ha base on openstack-base-70,but failed

hi.

I am going to deploy keystone ha base on openstack-base-70,fellow < Infrastructure high availability> with vip.

juju deploy -n 3 --to lxd:0,lxd:1,lxd:2 --config vip=10.0.7.12 keystoneLocated charm 
Located charm "cs:keystone-319".
Deploying charm "cs:keystone-319".
ERROR cannot add application "keystone": application already exists

so I change to fellow commands:

        juju add-unit --to lxd:1 keystone
        juju add-unit --to lxd:2 keystone
        juju deploy --config cluster_count=3 hacluster keystone-hacluster
        juju add-relation keystone-hacluster:ha keystone:ha
        juju set keystone vip=10.0.7.12 

    ERROR juju: "set" is not a juju command. See "juju --help".

    Did you mean:
            scp

so ,how can I set vip?

    juju add-unit --to lxd:1 keystone
    juju add-unit --to lxd:2 keystone
    juju config keystone vip=10.0.7.12 
    juju deploy --config cluster_count=3 hacluster keystone-hacluster
    juju add-relation keystone-hacluster:ha keystone:ha
