Docker MACVLAN issues

[validide]

Hi,

I am trying to setup Home Assistant in Docker and spinning-up the container fails due to the macvlan setup with "operation not supported".

Code: Select all

Error response from daemon: failed to create the macvlan port: operation not supported

System info:
Terra Master T6-423

Code: Select all

The docker macvlan configuration is:

Code: Select all

docker network create --config-only --subnet=192.168.0.0/24 --gateway=192.168.0.1 -o parent=eth0 --ip-range 192.168.0.232/29 macvlan_local_cfg
docker network create -d macvlan --config-from macvlan_local_cfg macvlan_network

I saw other post saying the problem was fixed by running the following but in my case this fails

Code: Select all

ip link add macvlan0 link eth0 type macvlan mode bridge
ip addr add 192.168.0.232/29 dev macvlan0
ip link set macvlan0 up

I get an error after the first command:

Code: Select all

ip link add macvlan0 link eth0 type macvlan mode bridge

RTNETLINK answers: Operation not supported

Did anyone run into similar issues of has any suggestion on what might cause the error?

Thanks!

Hello,
I think the error you are encountering with the "Operation not supported" message when trying to create a macvlan interface in Docker on your Terra Master T6-423 NAS is likely due to the kernel configuration on the NAS not supporting macvlan in bridge mode. If macvlan is not feasible, you can create a bridge network in Docker and connect your containers to this bridge. This might not provide the same level of isolation as macvlan but could be a workaround.

I have same issue on TOS6, did you manage to find a solution?
