Network related comminucation from KVM to Docker

I have somewhat of a weird problem with connecting to docker services from within a VM on KVM.  As an example, take the madsonic docker, I have a script that exports playlists from madsonic to kodi via the following command:

 

curl -u user:pass http://192.168.1.87:4040/playlistSettings.view?exportPlaylists

 

I keep on getting:

 

curl: (56) Recv failure: Connection reset by peer

 

Although telnetting to the madsonic docker seems to works fine. IP is set statically via /etc/network/interfaces in the VM.

 

The bridge is setup as follows:

root@Tower:~# brctl show
bridge name	bridge id		STP enabled	interfaces
docker0		8000.06b0e2381974	no		veth200632c
in0		8000.00110a152564	yes		eth1
						    vnet0

05:06.0 Ethernet controller: Intel Corporation 82546EB Gigabit Ethernet Controller (Copper) (rev 03)

The bridge is created on boot in the go file with:

 

brctl addbr in0
brctl stp in0 on
brctl addif in0 eth1
ifconfig eth1 up
ifconfig in0 up

 

Must be a routing problem with the bridge or something as I don't see eth1 in the routing table:

 

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
default         pfsense.localdo 0.0.0.0         UG    1      0        0 eth0
loopback        *               255.0.0.0       U     0      0        0 lo
172.17.0.0      *               255.255.0.0     U     0      0        0 docker0
192.168.1.0     *               255.255.255.0   U     0      0        0 eth0
192.168.122.0   *               255.255.255.0   U     0      0        0 virbr0

 

EDIT: I added the following route which seems to do the trick:

 

route add -net 192.168.1.0 netmask 255.255.255.0 dev in0

 

Wasn't aware I needed to do this, I'm assuming I'm going about this correct no?
