Teredo Network For Containers

You might develop your service as a container and you might to give a Teredo Network access to your Container service. You can use this container to giving Teredo Network access to your container or your host network.

To start teredo service for host network.

docker run -it --rm --privileged --network host ghcr.io/ahmetozer/docker-teredo

If you want to give a teredo network for your container, you can run below command.

# Please change container_name variable to your container id or name.
container_name="net-tools-service"

docker run -it --rm --privileged -v /proc/$(docker inspect -f '{{.State.Pid}}' $container_name)/ns/net:/var/run/netns/container ghcr.io/ahmetozer/docker-teredo

Starting teredo service at system startup, you can replace --rm arg with --restart always.
Note: This is only available for host network, because after restarting container pid are changed.

docker run -it --restart always --privileged --network host ghcr.io/ahmetozer/docker-teredo

After restarting your server or container for automate find pid and setting teredo, set container name as variable and bind proc and docker socket to container.

docker run -it --rm --privileged -e container_name=net-tools-service -v /proc/:/proc2/ -v /var/run/docker.sock:/var/run/docker.sock --name teredo ghcr.io/ahmetozer/docker-teredo

You might to remove default IPv6 access and only give Teredo access, set delro environment variable to yes. delro (Delete Default Route) function is has a backup mechanism. When the teredo container closes well, system reload old IPv6 routes to first container.
With multiple table support for this software,you can serve any service with real IPv6 addresses, your IPv6 address is also accessible while teredo running but default IPv6 request which is created by inside the container is use teredo interface to go outside. This system is not break BGP and RPKI rules. NOTE: I disabled delro in host to prevent any user mistake to delete default route on main network (Outside of container). (You might break containers IPv6 network.)

docker run -it --rm --privileged -e container_name=net-tools-service -e delro=yes -v /proc/:/proc2/ -v /var/run/docker.sock:/var/run/docker.sock --name teredo ghcr.io/ahmetozer/docker-teredo
