Following https://lowtek.ca/roo/2025/nixos-docker-with-macvlan-ipv4/ & https://fictionbecomesfact.com/notes/pihole-container-setup/ (#nixos version) I have a pihole container running that from other PCs on my LAN I can:
Ping to it
Ping from it
Observe in the pihole WUI that it is issuing DNS replies
TShark on the #podman host sees #dns queries but no responses
What more can I do? I assume it is something about #macvlan, but ping is happy. So I'm very confused. #AskFedi
NixOS + Docker with MacVLAN (IPv4) – Roo's View

🔥 Cách Cấu Hình IPv6 Giữa UDM Và IP Übergang DNS 🌐

Tắt ukserver, IPv6 trên Comcast easy với GUI. Đaminton ở fe08 (dựa trên MAC) cho Adguard & Node Proxy. Đặt MAC statum hoặc IP4 statum → IPv6 DNS ổn định. Luôn dùng même sau chuyển ISP/mirror.

Stell dir vor, du hast zwei Spielzeuge: Pihole und NextCloud. Beide wollen auf dem gleichen Platz spielen. Das ist wie wenn zwei Kinder auf demselben Stuhl sitzen wollen.

Jetzt kommt Macvlan wie eine Zauberfee und sagt: "Ich habe eine Idee! Wir geben NextCloud einen eigenen, besonderen Stuhl!"

So machen wir das:
Wir basteln einen neuen, magischen Stuhl für NextCloud.
Wir sagen NextCloud, dass es auf diesem neuen Stuhl sitzen soll.
Wir geben NextCloud eine besondere Nummer (wie eine Hausnummer), damit es seinen Stuhl immer findet.
Jetzt kann NextCloud auf seinem eigenen Stuhl sitzen, und Pihole bleibt auf seinem alten Platz.

I found out that I couldn't create a #macvlan using #WiFi. Then I found that my #Unifi Ethernet switches don't really support #Vlans. I'm able to create secondary networks but I can't seem to get my macvlans to connect to the outside. But hey I was at least able to finally create a mcvlan to work. #Finally!
I get it! #docker can do what I want. I just can't do it! I'm knowledgeable enough to understand that I can set up #macvlan networks so I can run my containers on their own IP addresses, but I'm not smart enough to actually implement it. I need a PhD appearently. No matter how detailed the "how to" is, I literally type exactly the text characters, I will always assume that an error is coming. I can Google it and fix it, another one is the result! How the frick is this supposed to help me?

Not even 9am and I've got my #macvlan #docker setup sorted

Some #containers now on their own #VLAN that doesn't have access to the #LTE backup in #Unifi so they can't chew through my limited backup bandwidth if it kicks in

Neat

I foresee a weekend poking around with #macvlan's in #Docker
My #Pihole uses now a custom #docker #bridge network besides the #macvlan #network. The bridge is accessible by the host and Pi-hole. This is nice.

I can't access the #docker host from my images running in a #macvlan #network. This is by design but I found this quite old article to workaround: https://blog.oddbit.com/post/2018-03-12-using-docker-macvlan-networks/

I'll report!

Using Docker macvlan networks

A question that crops up regularly on #docker is “How do I attach a container directly to my local network?” One possible answer to that question is the macvlan network type, which lets you create “clones” of a physical interface on your host and use that to attach containers directly to your local network. For the most part it works great, but it does come with some minor caveats and limitations. I would like to explore those here.
