Running multiple transmission containers with different VPNs on same host

[Troubadoure]

Is it possible to run multiple containers using different VPN connections on the same host?

I've tried to do it but had no joy. I think they're using the same tun device and as such the VPN conflicts with each other. Would this be something that is possible or not at all?

i could without problems run multiple vpn on host, i had to because i can't get it working to use more than 51 containers through one vpn.

just change the port for every vpn you create (example down)
and then run your container with
--net=container:vpn1 and the other one with --net=container:vpn2

sudo docker run --cap-add=NET_ADMIN --device=/dev/net/tun -ti \
              --name vpn1 \
              --sysctl net.ipv6.conf.all.disable_ipv6=0  \
              -e OPENVPN_PROVIDER=yourprovidor \
              -e OPENVPN_CONFIG=country \
              -e OPENVPN_USERNAME=username \
              -e OPENVPN_PASSWORD=password \
              -e OPENVPN_OPTS="--inactive 3600 --ping 10 --ping-exit 60" \
              -e LOCAL_NETWORK=10.0.0.0/24 \
              -e WEBPROXY_ENABLED=true \
              -e ENABLE_UFW=true \
              --log-driver json-file \
              --log-opt max-size=10m \
              -p 9091:9091 \
              -e UFW_EXTRA_PORTS=5800 \
              -p 5800:5800 \
              --restart=always \
              haugene/transmission-openvpn

sudo docker run --cap-add=NET_ADMIN --device=/dev/net/tun -ti \
              --name vpn2 \
              --sysctl net.ipv6.conf.all.disable_ipv6=0  \
              -e OPENVPN_PROVIDER=yourprovidor2 \
              -e OPENVPN_CONFIG=country2 \
              -e OPENVPN_USERNAME=username2 \
              -e OPENVPN_PASSWORD=password2 \
              -e OPENVPN_OPTS="--inactive 3600 --ping 10 --ping-exit 60" \
              -e LOCAL_NETWORK=10.0.0.0/24 \

              -e ENABLE_UFW=true \
              --log-driver json-file \
              --log-opt max-size=10m \
              -p 9092:9091 \
              -e UFW_EXTRA_PORTS=5800 \
              -p 5800:5800 \
              --restart=always \

Merged a feature to the dev branch that creates the TUN device automatically inside the container so it doesn't need to be mounted from the host. Then at least it should be no problem. It seems to be working really well so it will become the new default behaviour and released to master soon.

Closing this.
