Ziel

pihole und unbound in jeweils einem eigenen Container, um mögliche Port Konflikte zu vermeinden.
Es wird macvlan verwendet

Was gegen diese Lösung mit den macvlan spricht: https://blog.oddbit.com/post/2018-03-12-using-docker-macvlan-networks/

Netzwerk einrichtung MACVLAN

Erstelle unter „Networks“ ein neues Netzwerk:

• Name: mypiholevlan
• Driver: macvlan
• Parent network: eth0 (den richtigen Adapter auswählen, mit dem das VLan verknüpft sein soll)
• Subnet: „192.168.130.0/24“
• Gateway: „192.168.130.1“ (Im Regelfall der Router)
• IP range: „192.168.130.12/30 # 192.168.130.12 and 192.168.130.13“ (Kann frei bleiben, sofern man die IP-Adressen selbst und ohne DHCP verteilet.
  Alternativ reserviert man ein paar IP-Adressen, die von Docker verwendet werden dürfen und nicht per DHCP genutzt werden.)
