Hello,

I am working to install Zun on a OpenStack instance, so I'm required to set up Docker with kuryr-libnetwork.

I see that there are three possible approaches:

• Running it inside a service container, using the Docker Engine on the compute nodes (https://opendev.org/openstack/kuryr-libnetwork#getting-it-running-with-a-service-container)
• Installing it directly on the compute nodes (https://opendev.org/openstack/kuryr-libnetwork#getting-it-running-with-a-service-container)
• Installing it as a Docker plugin (https://opendev.org/openstack/kuryr-libnetwork#getting-it-running-with-a-service-container)

Does anyone know the advantages/disadvantages of the three approaches? I've tried to find a comparison, but the OpenStack docs only include a procedure to install it on a Ubuntu Compute Node (https://docs.openstack.org/kuryr-libnetwork/latest/install/compute-install-ubuntu.html)

Best regards

Francesco Di Nucci
