Containerized versions of Open vSwitch built originally for use by
Kelda. Despite their original intent, there is nothing
Kelda specific about them, thus they should be generally useful.
The keldaio/ovs container can run
ovn-controller. It chooses which flavor to boot based on a command line
argument (examples below).
The containers have several initialization requirements that make running them
slightly different than typical docker containers. The most important
of which is the necessity that all containers run on the host's network stack.
For example, the proper way to boot
ovsdb-server, the simplest of the
containers, is as follows:
docker run -itd --net=host --name=ovsdb-server keldaio/ovs ovsdb-server
All of the other flavors require several volumes containing the OVS database,
logs, and configuration files. These must be mounted from a running
ovsdb-server container as follows:
docker run -itd --net=host --volumes-from=ovsdb-server keldaio/ovs ovn-northd docker run -itd --net=host --volumes-from=ovsdb-server keldaio/ovs ovn-controller
Finally, Open vSwitch needs to interact with the OVS kernel module in the host,
and therefore must be run in privileged mode.
docker run -itd --net=host --volumes-from=ovsdb-server --privileged keldaio/ovs ovs-vswitchd
