Containerized-ovs-forwarder

This repository builds a container image for ovs forwarder. Also it implement two ovs modules:

• The containerovsdb which connect to ovs container and create bridges and vdpa ports.
• The ovsdb which connect to ovs on the host

The ovs modules were taken from openstack/os-vif.

Build ovs-forwarder container image

Go to build directory

$ cd build/

Specify the MLNX_OFED_VERSION and run the build command

$ MLNX_OFED_VERSION=50218 /bin/bash build.sh

Now the ovs-docker image created successfully

Build OVS container

Once the image is ready, you can create the container by running container_create script:
Pass the required arguements to container_create,

--port <port_number> OVS manager port default to 6000

--pci_args <pci_address> <vfs_range> A pci address of dpdk interface and range of vfs

In case of bonding or you have more than one NIC for dpdk, reuse the --pci_args

--pmd-cpu-mask <mask> A core bitmask that sets which cores are used by OVS-DPDK for datapath packet processing

$ MLNX_OFED_VERSION=50218 /bin/bash container_create.sh --pci_args 0000:02:00.0 0-3 --port 6000 

Now the ovs-forwarder created successfully

Start OVS container

Then start the contaier by running:

$ docker start ovs-forwarder:$MLNX_OFED_VERSION

Use ovs_modules

You can use the python/example.py script in order to use ovs modules
The script creates netdev bridge and vdpa port on the container, and also create a bridge and plug representor port on the host
Before using the ovs modules make sure that the requirements in requirements.txt are installed

$ cd python
$ python example.py
