    it's me or docker dns doesn't work?

     

    if I have 2 containers and i want to have access to one of the containers from the other using the docker name, it's not working. neither from the host, is like docker DNS is not enabled...

    tried in a clean installation and happens.. so is this intended?... any way to enable it?
    Thanks!

    Nobody else has reported this so I think it is most likely you.

     

    My dockers can talk to each other.

     

    I guess after you post diagnostics we will know which 6.8 you are running.

    HI @trurl thanks for your help,

    I'm running 6.8.2 on 2 diferents machines, I also testing 6.9-beta25

    I tried to run clean installation in a VM to test this and always is happening on all the machines.

    please try this to check that its not working on default unraid installation.

    docker run -itd  --name busybox01 -h busybox01 busybox
    docker run -itd  --name busybox02 -h busybox02 busybox
    docker exec -it busybox01 ping -c 2 busybox02

     

    if we use default unraid bridge same..

    docker run -itd  --network=bridge --name busybox01 -h busybox01 busybox
    docker run -itd  --network=bridge --name busybox02 -h busybox02 busybox
    docker exec -it busybox01 ping -c 2 busybox02

     

    but if we use created one by us...

    docker network create -d bridge mybridge01
    docker run -itd --network=mybridge01 --name busybox01 -h busybox01 busybox
    docker run -itd --network=mybridge01 --name busybox02 -h busybox02 busybox
    docker exec -it busybox01 ping -c 2 busybox02

    then it works
