OK thanks, perhaps Girish can comment, I thinking that the steps are
|# Create OVN namespace, service accounts, ovnkube-db headless service,
configmap, and policies kubectl create -f
$HOME/work/src/github.com/ovn-org/ovn-kubernetes/dist/yaml/ovn-setup.yaml
# Run ovnkube-db deployment. kubectl apply -f
$HOME/work/src/github.com/ovn-org/ovn-kubernetes/dist/yaml/||ovnkube-db-raft.yaml # Run ovnkube-master deployment. kubectl create -f
$HOME/work/src/github.com/ovn-org/ovn-kubernetes/dist/yaml/ovnkube-master.yaml
# Run ovnkube daemonset for nodes kubectl create -f
$HOME/work/src/github.com/ovn-org/ovn-kubernetes/dist/yaml/ovnkube-node.yaml|

I don't see any ovn-northd.log log, I only see those when I'm running
OVN outside the k8s cluster.
Before I start the Satefulset on my k8 nodes I run:
ovn-ctl stop_northd
ovn-ctl stop_ovsdb
rm -rf /usr/etc/ovn/*.db
The only logs I see are ovn-controller.log (I'm running ovn controller
on the K8 nodes) ovsdb-server-nb.log ovsdb-server-sb.log
These logs look normal
ovn-northd is the daemon that translates OVN_Northbound DB records to
OVN_Southbound DB records (including logical flows). If your deployment
doesn't start ovn-northd SB won't get populated.
Well I use the ovnkube-db-raft.yaml and ovn-setup.yaml as per the
documentation, and they call
ovndb-raft-functions.sh and start the OVN procs as:
run_as_ovs_user_if_needed \
${OVNCTL_PATH} run_${db}_ovsdb --no-monitor \
--db-${db}-cluster-local-addr=[${ovn_db_host}] \
--db-${db}-cluster-local-port=${raft_port} \
--db-${db}-cluster-local-proto=${transport} \
${db_ssl_opts} \
--ovn-${db}-log="${ovn_loglevel_db}" &
This seems to be starting the NB/SB DBs only.
Are you saying that there is more to do?? as in invoke run-ovn-northd()
Yes, something has to start ovn-northd.
in ovnkube.sh which is called
from the ovnkube-master.yaml file? I see that
https://github.com/ovn-org/ovn-kubernetes says
Apply OVN DaemonSet and Deployment yamls.

But makes no mention of ovnkube-db-raft.yaml ?? so is the above is the
correct procedure?
what then is ovnkube-db-raft.yaml for?
I'm not sure about the ovnkube specifics, I'll let someone from the
ovn-k8s team comment about this. But as mentioned above, something needs
to start ovn-northd otherwise the SB won't get populated.

Note I don't want to replace flannel with OVN as the CNI, I just want to
run OVN central in a k8
StatefulSet, that use flannel as the CNI.
Is it documented anywhere how I can do this? I would have thought that
ovnkube-db-raft.yaml
was the way to go, and that it would start all that is needed??
Do I need to run all of the above yamls too, or just a subset? and will
they interfere with ovnkube-db-raft.yaml
and/or flannel? Do I need to just drop ovnkube-db-raft.yaml???
Can someone provide the exact yamls I need to do this please
Thanks
Brendan.
