More context

Trending Docker discussions focus on practical deployment and networking: running Docker on Proxmox/VMs, setting up reliable container networking (including macvlan), and troubleshooting networking/proxy issues. There’s also active interest in orchestration approaches like connecting Docker Swarm clusters with Kubernetes.

How to approach running a background command at a repeated interval?

Without Docker involved, I'd quite happily use systemd-timers tbh... but to my surprise there doesn't appear to be any well-established standalone alternative program for running a command at a recurring interval? (unles…

NEW: Proxmox in a Docker container

I created a Docker container of Proxmox VE. This makes it extremely easy to install Proxmox on existing systems, and to play around with it before deciding on dedicating a whole machine to it. The performance should be i…

Common questions on Docker, surfaced from across the indexed web.

What is Docker macvlan used for?

Docker macvlan gives containers their own MAC address and IP address on your physical network, eliminating the need for NAT or port mapping. It’s most useful when a container needs to appear as a real device on a specific subnet — common for Wake-on-LAN tools, network scanners, and IoT management containers that need to be on a dedicated VLAN.

Docker Macvlan on a VLAN: Give Containers Their Own IP - WunderTech
Can a Docker macvlan container communicate with the host?

Not by default. Macvlan isolates the container from the host at the network level, so the container can talk to other devices on the VLAN but not the machine it’s running on. To work around this, you can create a macvlan interface on the host side as well (sometimes called a shim interface), which gives the host an IP on the macvlan network.

What’s the difference between macvlan and bridge networking in Docker?

With bridge networking, containers share the host’s IP and use NAT to reach the outside world. With macvlan, each container gets its own IP directly on your physical network — no NAT, no port forwarding. Macvlan behaves more like adding a new device to your network, while bridge networking behaves more like a software router sitting between the container and your LAN.

Why is my macvlan container unreachable even though Docker shows it running?

The most likely cause is a VLAN tagging gap somewhere in the chain. Check that: (1) the VLAN subinterface on the host is up (ip link show), (2) the Docker macvlan network is using the subinterface as parent — not the raw physical interface, (3) the upstream switch port is configured as a trunk that allows your VLAN, and (4) the IP you assigned isn’t conflicting with another device on that VLAN.
