VLAN subnet is not available as docker custom networks

[Surfparadise]

I enabled VLAN in network configuration, but the vlan custom network in docker is not present.

 

I configured the 254 vlan on my router, and seems to works.

If I ping 192.168.254.1 from a client in my network it's reply, but If I try to ping it from my unraid terminal, it is not reachable.

 

Anyone can help me? Thanks

 

 

 

 

 

 

 

No problem on VMs:

Make sure you also have the vlan enabled on the settings > docker page.
First define vlan in settings > network settings

Then go to settings > docker
Stop the docker service
add the vlan

start the docker service

Now you should see it when you're adding containers.

Might have to make sure to click the little "advanced" tab in the top right, don't remember if you need to be in advanced or not.

Seems to be ok:

Only differences from mine, I define my gateway.  I have "preserve user defined networks" set to yes.

Also, use ipvlan, and do not use macvlan.  macvlan is considered buggy right now and new versions default to ipvlan.

I found this in the unraid logs:

 

Apr 13 14:05:34 Unraid root: Error response from daemon: failed to allocate secondary ip address (server:192.168.254.0): Address already in use

My Network settings for my vlans look like this:


FYI, I don't have any routes defined in my routing table for my vlans.

 

I manually define IP addresses for each container I put on my vlans, I don't use DHCP.

Hello, I had the same problem. I solved it this way:

Unraid IP 192.168.1.20/16, GW 192.168.0.1 metric 1

VLAN IP 10.0.0.20/24, GW 10.0.0.1 metric 2

I am having this same problem where the VLANs are not showing up. The following VLANs do not show up in the list for the individual docker container.

Got it to work by setting the IPv4 Address Assignment for VLANs under Settings page to be None
