Alfredo Moralejo c4c6958622 Use centos8 deps repo for RHEL8 nodes
CentOS8 deps should be compatible with RHEL and provide latest versions
of deps compared to the old rhel8 one. Let's switch to use it to install
openvswitch too.

Configures a VXLAN virtual network overlay through an openvswitch network bridge between a 'switch' node and 'peer' nodes.

This allows members of the bridge to communicate with each other through the virtual network.

By default, this role will:

  • Install and start openvswitch
  • Set up a br-infra bridge on all nodes
  • Set up the connectivity between the switch and the peer with a virtual port
  • Set up an ip address on the bridge interface:
172.24.4.1/23 # switch node
172.41.4.2/23 # first peer
172.41.4.3/23 # second peer
...

Role requirements

This role requires and expects two groups to be set up in the Ansible host inventory in order to work:

  • switch (the node acting as the switch)
  • peers (nodes connected to the virtual switch ports)
