Anyone know what the cause of this is?

In syslog ...
 
'
rc.docker: Error response from daemon: Pool overlaps with other one on this address space'

 
Seen it a few times recently.

Check at Settings -> Docker -> upper right switch to advanced view

What Networks are set?

Seems like one is overlapping maybe a Subnet typo or using a Subnet like the standard 172 Network.

I only have Maria and nextcloud dockers installed as preconfigured.

Sounds good, and what networks did you configure? Did you run at some point 'docker network create'? As I mentioned before this will setup a network using the 172 as the first octet for the Network Subnet.

They are using 172.17.0.2 & 3 respectively. No command line input at all. In bridge mode.

Do they only use 172.17.0.2? Or is it set like:

172.17.0.2:80 192.168.1.2:80

You can have a look in the Docker Tab.

But as I mentioned before please have a look at the advanced docker settings if there are more than one network set within the same Subnet, there is your Problem.

Where are the advanced docker settings? Can't see them under advanced view on the dockers page itself? And yes, there is a :xxx.xxx.xxx. type entry alongside.

Ok ... i've found them and my br2/br3 look like this

 

IPv4 custom network on interface br2:  Subnet: 192.168.2.0/24 Gateway: DHCP pool: not set
IPv4 custom network on interface br3:  Subnet: 192.168.2.0/24 Gateway: DHCP pool: not set
 
Subnet: 192.168.1.0/24 Gateway: 192.168.1.1 DHCP pool: not set
 
Could this be the cause and nothing to do with the existing dockers?

Exactly. Just remove one of the Cables, if possible, and try again. Or stop all containers go into the docker settings and remove one of them by deselect them.

So ... there's a conflict somewhere? What needs to change? Do I need a new address for br3? None of these have a cable attachment or any dockers using the range yet.
