# This system unit is used to manage OVN DB daemons.
# It supports all '_ovsdb'-ending commands in
# /usr/share/ovn/scripts/ovn-ctl script. Consult it for additional info.
#
# Each OVN DB systemd unit instance name %i (a part after '@' symbol) must match
# with appropriate ovn-ctl subcommand, which starts and ends with 'start_' and
# '_ovsdb' respectively.
# User must provide appropriate environment variable 'ovn_$i_opts' either in
# /etc/sysconfig/ovn, in /etc/sysconfig/ovn-%i or in
# /etc/systemd/system/ovn-db@%i.service.d/local.conf file.
#
# For example, to configure ovn-db@sb daemon, which runs ovsdb-server with
# OVN_Southbound database schema, you should define variable 'ovn_sb_opts' in
# /etc/systemd/system/ovn-db@sb.service.d/local.conf:
#
#   [System]
#   Environment="ovn_sb_opts=--db-sb-sock=/usr/local/var/run/ovn/ovnsb_db.sock"
#
# Alternatively, you may specify environment variable in the /etc/sysconfig/ovn-sb file:
#
#   ovn_sb_opts="--db-sb-sock=/usr/local/var/run/ovn/ovnsb_db.sock"
