This series of tutorials deals with networking standalone containers which
connect to `macvlan` networks. In this type of network, the Docker host accepts
requests for multiple MAC addresses at its IP address, and routes those requests
to the appropriate container. For other networking topics, see the
[overview](/manuals/engine/network/_index.md).
## Goal
The goal of these tutorials is to set up a bridged `macvlan` network and attach
a container to it, then set up an 802.1Q trunked `macvlan` network and attach a
container to it.
## Prerequisites
- Most cloud providers block `macvlan` networking. You may need physical access
to your networking equipment.
- The `macvlan` networking driver only works on Linux hosts, and is not supported
on Docker Desktop or Docker Engine on Windows.
- You need at least version 3.9 of the Linux kernel, and version 4.0 or higher
is recommended.
- The examples assume your ethernet interface is `eth0`. If your device has a
different name, use that instead.
- The `macvlan` driver is not supported in rootless mode.
## Bridge example
In the simple bridge example, your traffic flows through `eth0` and Docker
routes traffic to your container using its MAC address. To network devices
on your network, your container appears to be physically attached to the network.
1. Create a `macvlan` network called `my-macvlan-net`. Modify the `subnet`, `gateway`,
and `parent` values to values that make sense in your environment.
```console
$ docker network create -d macvlan \
--subnet=172.16.86.0/24 \
--gateway=172.16.86.1 \
-o parent=eth0 \
my-macvlan-net
```
You can use `docker network ls` and `docker network inspect my-macvlan-net`
commands to verify that the network exists and is a `macvlan` network.
2. Start an `alpine` container and attach it to the `my-macvlan-net` network. The
`-dit` flags start the container in the background but allow you to attach
to it. The `--rm` flag means the container is removed when it is stopped.
```console
$ docker run --rm -dit \
--network my-macvlan-net \
--name my-macvlan-alpine \
alpine:latest \
ash
```
3. Inspect the `my-macvlan-alpine` container and notice the `MacAddress` key
within the `Networks` key:
```console
$ docker container inspect my-macvlan-alpine

4. Check out how the container sees its own network interfaces by running a
couple of `docker exec` commands.
```console
$ docker exec my-macvlan-alpine ip addr show eth0
9: eth0@tunl0: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue state UP
link/ether 02:42:ac:10:56:02 brd ff:ff:ff:ff:ff:ff
inet 172.16.86.2/24 brd 172.16.86.255 scope global eth0
valid_lft forever preferred_lft forever
```
```console
$ docker exec my-macvlan-alpine ip route
default via 172.16.86.1 dev eth0
172.16.86.0/24 dev eth0 scope link src 172.16.86.2
```
5. Stop the container (Docker removes it because of the `--rm` flag), and remove
the network.
```console
$ docker container stop my-macvlan-alpine
$ docker network rm my-macvlan-net
```
## 802.1Q trunked bridge example
In the 802.1Q trunked bridge example, your traffic flows through a sub-interface
of `eth0` (called `eth0.10`) and Docker routes traffic to your container using
its MAC address. To network devices on your network, your container appears to
be physically attached to the network.
1. Create a `macvlan` network called `my-8021q-macvlan-net`. Modify the
`subnet`, `gateway`, and `parent` values to values that make sense in your
environment.
```console
$ docker network create -d macvlan \
--subnet=172.16.86.0/24 \
--gateway=172.16.86.1 \
-o parent=eth0.10 \
my-8021q-macvlan-net
```
You can use `docker network ls` and `docker network inspect my-8021q-macvlan-net`
commands to verify that the network exists, is a `macvlan` network, and
has parent `eth0.10`. You can use `ip addr show` on the Docker host to
verify that the interface `eth0.10` exists and has a separate IP address
2. Start an `alpine` container and attach it to the `my-8021q-macvlan-net`
network. The `-dit` flags start the container in the background but allow
you to attach to it. The `--rm` flag means the container is removed when it
is stopped.
```console
$ docker run --rm -itd \
--network my-8021q-macvlan-net \
--name my-second-macvlan-alpine \
alpine:latest \
ash
```
3. Inspect the `my-second-macvlan-alpine` container and notice the `MacAddress`
key within the `Networks` key:
```console
$ docker container inspect my-second-macvlan-alpine

couple of `docker exec` commands.
```console
$ docker exec my-second-macvlan-alpine ip addr show eth0
11: eth0@if10: <BROADCAST,MULTICAST,UP,LOWER_UP,M-DOWN> mtu 1500 qdisc noqueue state UP
link/ether 02:42:ac:10:56:02 brd ff:ff:ff:ff:ff:ff

default via 172.16.86.1 dev eth0
172.16.86.0/24 dev eth0 scope link src 172.16.86.2
```
5. Stop the container (Docker removes it because of the `--rm` flag), and remove
the network.
```console
$ docker container stop my-second-macvlan-alpine
$ docker network rm my-8021q-macvlan-net
```
