EXTRA OPTIONS¶
Any options after ’-’ will be passed on to the binary run by command with the exception of start_northd, which can have options specified in ovn-northd-db-params.conf. Any extra_args passed to start_northd will be passed to the ovsdb-servers if --ovn-manage-ovsdb=yes
CONFIGURATION FILES¶
Following are the optional configuration files. If present, it should be located in the etc dir
ovnnb-active.conf¶
If present, this file should hold the url to connect to the active Northbound DB server
tcp:x.x.x.x:6641
ovnsb-active.conf¶
If present, this file should hold the url to connect to the active Southbound DB server
tcp:x.x.x.x:6642
ovn-northd-db-params.conf¶
If present, start_northd will not start the DB server even if --ovn-manage-ovsdb=yes. This file should hold the database url parameters to be passed to ovn-northd.
--ovnnb-db=tcp:x.x.x.x:6641 --ovnsb-db=tcp:x.x.x.x:6642
ic-nb-active.conf¶
If present, this file should hold the url to connect to the active Interconnection Northbound DB server
tcp:x.x.x.x:6645
ic-sb-active.conf¶
If present, this file should hold the url to connect to the active Interconnection Southbound DB server
tcp:x.x.x.x:6646
ovn-ic-db-params.conf¶
If present, this file should hold the database url parameters to be passed to ovn-ic.

RUNNING OVN DB SERVERS WITHOUT DETACHING¶
# ovn-ctl run_nb_ovsdb
This command runs the OVN nb ovsdb-server without passing the detach option, making it to block until ovsdb-server exits. This command will be useful for starting the OVN nb ovsdb-server in a container.
# ovn-ctl run_sb_ovsdb
This command runs the OVN sb ovsdb-server without passing the detach option, making it to block until ovsdb-server exits. This command will be useful for starting the OVN sb ovsdb-server in a container.
# ovn-ctl run_ic_nb_ovsdb
This command runs the OVN IC-NB ovsdb-server without passing the detach option, making it to block until ovsdb-server exits. This command will be useful for starting the OVN IC-NB ovsdb-server in a container.
# ovn-ctl run_ic_sb_ovsdb
This command runs the OVN IC-SB ovsdb-server without passing the detach option, making it to block until ovsdb-server exits. This command will be useful for starting the OVN IC-SB ovsdb-server in a container.
EXAMPLE USAGE¶
Run ovn-controller on a host already running OVS¶
# ovn-ctl start_controller
Run ovn-northd on a host already running OVS¶
# ovn-ctl start_northd
All-in-one OVS+OVN for testing¶
# ovs-ctl start --system-id="random"
# ovn-ctl start_northd
# ovn-ctl start_controller
Promote and demote ovsdb servers¶
# ovn-ctl promote_ovnnb
# ovn-ctl promote_ovnsb
# ovn-ctl --db-nb-sync-from-addr=x.x.x.x --db-nb-sync-from-port=6641 --db-nb-probe-interval-to-active=60000 demote_ovnnb
# ovn-ctl --db-sb-sync-from-addr=x.x.x.x --db-sb-sync-from-port=6642 --db-sb-probe-interval-to-active=60000 demote_ovnsb
Creating a clustered db on 3 nodes with IPs x.x.x.x, y.y.y.y and z.z.z.z¶
