Configuringipv6fordockercontainerdoesnotwork

on

The docker container is running on a system which is ipv6 enabled. When the docker container executes ping -6 2001:4860:4860::8888 100% of the packets are lost. ping 8.8.8.8 works fine.

I added this to daemon.json:

{
"ipv6": true,
"fixed-cidr-v6": "2003:e1:bbe7:500:8000::/65"
}

This is the assigned ipv6 address from the container:

2003:e1:bbe7:500:8000:242:ac11:2/65

While this is the main os ipv6 address:

2003:e1:bbe7:500:b237:dea4:d9e4:e05f

Added the ip to docker0 interface:

4: docker0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default 
    link/ether 02:42:3c:d3:aa:fc brd ff:ff:ff:ff:ff:ff
    inet 172.17.0.1/16 brd 172.17.255.255 scope global docker0
       valid_lft forever preferred_lft forever
    inet6 2003:e1:bbe7:500:8000::1/65 scope global 
       valid_lft forever preferred_lft forever

What I tried so far:

  • successfully accessed the google dns from a ipv6 enabled VM (thats why I'd guess its a docker related issue, not firewall related)
