Eclipse fog05 with ETSI OSM Orchestrator

Edit on GitHub

Eclipse fog05 is compatible with ETSI OSM, and can be used as a VIM by this one. Current interoperability is limited to simple NS using LXD containers as VNFs.

Let’s suppose we have a multi node fog05 deployment and we want to connect this deployment to OSM to instantiate VNFs.

First let’s add the VIM account to OSM

osm vim-create --name fos --auth_url <zenoh server ip>:7447 --account_type fos --tenant osm --user dummy --password dummy --config '{hypervisor: LXD}'

Following paramater can be added

arch cpu architecture used when creating the VDUs for this VIM account eg. x86_64, aarch64, default is x86_64.
hypervisor hypervisor supported by this VIM account, can be one of: LXD, KVM, BARE, DOCKER, ROS2, at least one node of the system as to be able to manage the selected hypervisor, currently only LXD is supported within the OSM connector.

Images need to be already present at the VIM.

Example NS

Here you can find and example of network service that can be instantiated to the Eclipse fog05 VIM using OSM. The network service is composed by a single VNF based on an Alpine Linux LXD image.

VLAN Configuration (optional)

If you want your fog05 installation to be able to use VLANs for virtual networks instead of overlay VxLANs you need to change the configuration on all nodes. You need to update the configuration file /etc/fos/plugins/linuxbridge/linuxbridge_plugin.json.

 "version": 1,
