Docker takes care of the networking aspects so that the containers can communicate with other containers and also with the Docker Host. Seems like it keeps "looping over" Requesting Address from the new subnet. But service doesn't seem to spawn any containers. Then simply enable and start the systemd service and you're good to go.I am using 17.05 for my manager and worker nodes and am trying to create a new ingress network with custom subnet and then creating swarm service. mount=type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock \ The service I'm running in the example is the Docker Swarm visualizer. The systemd unit is as follows ( ĮxecStart=/usr/bin/socat -ly TCP6-LISTEN:$Īnd the env file just contains two lines which give it the ports, for example ( /etc/nf): SOURCEPORT=8080 The bind there is optional, but handy if you want to limit access. Let's say your actual service wants to listen on port 8080, so instead make it listen on 8081 and socat IPv6 connections from 8080 to 8081. It is recommended that you use separate overlay networks for each application or group of applications which will work together.
If you create swarm services and do not specify a network, they are connected to the ingress network. I created a small systemd service that starts after rvice so it ought to be fairly resilient. The dockergwbridge connects the ingress network to the Docker host’s network interface so that traffic can flow to and from swarm managers and workers. So the workaround I came up with is socat. I tried creating different types of ingress networks, modifying the docker_gwbridge and whatnot, but IPv6 support is just bad. I have exactly the same situation, and so far I have not come up with an actual solution, but rather a simple workaround. I get same error when I do not specify any ip addresses. I am not sure even when I specified my own overlay network in the docker compose its falling back to ingress network. var/run/docker.sock:/var/run/docker.sockīut when I start my swarm services I get error in /var/log/docker.log as, time="T12:09:19.693307864+05:30" level=error msg="fatal task error" error="Invalid address 2002:ac0b::2: It does not belong to any of this network's subnets" module=node/agent/taskmanager node.id=luqw5to6dike43h88h25xj7tg service.id=tfttw36jqmsq3ew6wzn61gyku task.id=7jo89apxj585pdtacmr2d7jpe I configured my container to use the overlay network ipv6_overlay with predefined ip addresses, /mnt/share/sunils/repos/github/ec2-sample-docker $ cat docker-compose.yml ".overlay.vxlanid_list": "4106,4107"Īlso created new overlay network ipv6_overlay that I would be using from my containers, ~ $ docker network inspect ipv6_overlay I am not able to reach the service over ipv6 on localhost, I have to use curl -4 instead of curl While investigation I found out that the docker ingress network does not have ipv6 enabled, so I created removed older one and created new ingress network with ipv6 address ~ $ docker network inspect ingress I am trying to figure out issue with my docker network setup, ( docker containers give out blank ipv6 address)
