docker-compose.yml

# This docker-compose file was provided by @Heinicke in the official Discord
# channel (Shinykey#4602), so all credit goes to them.
# This is not a functional example since your VLAN environment and interface
# names will probably be unique to you. Perform an `ip addr show` to see your
# options, and then just modify this config like this:
#
# driver_opts:
#    parent: <interface name>.<vlan number>
#
# In the current setup the parent network interface (enp5s0) has a single
# connection to the switch which is a trunk with VLAN 10, 20, 30 and 40, all of
# which will be correctly forwarded to the DHCP service.
# The upstream switch will then only need to be set up to properly forward
# the correct VLANs on this trunk.
