Ubuntu support

Does this works on Ubuntu?

I'm getting this error:

[openshift/dind] Step 8/17 : RUN dnf -y update && dnf -y install docker glibc-langpack-en iptables openssh-clients openssh-server tcpdump [openshift/dind] ---> Running in a43e799706b8 [openshift/dind] Error: Failed to synchronize cache for repo 'updates' [openshift/dind] The command '/bin/sh -c dnf -y update && dnf -y install docker glibc-langpack-en iptables openssh-clients openssh-server tcpdump' returned a non-zero code: 1 [ERROR] hack/dind-cluster.sh:800: return "${result}" exited with status 1. /root//go/src/github.com/openshift/origin/run.sh: line 6: /root/go/src/github.com/openshift/origin/dind-openshift.rc: No such file or directory

Thank you

Should work on Ubuntu. It seems a network issue happened during the initial build of the images. If you retry, do you get the same error?

I tried the network at work and home and same issue :(

Could you send your docker info output please?

[gustavocoding]

I guess there is something wrong in your env that prevents docker build to download from the internet. You can try with a test, create a simple Dockerfile:

FROM fedora:27

RUN dnf -y update && dnf -y install\
 docker\
 glibc-langpack-en\
 iptables\
 openssh-clients\
 openssh-server\
 tcpdump

and then

docker build -t sample .

This is my docker info.:

Let me try your test... thanks!

Your sample didn't work but I think I've found the issue:

I need to pass --network host to the build command otherwise the containers have no connectivity.

But I do not know why I need to do this, may be an Ubuntu issue. Do you have any ideas?

I will continue investigating tomorrow.

Thank you very much.

It seems Ubuntu has DNS issues with docker. So one workaround would be to add 8.8.8.8 to the /etc/docker/daemon.json in the end of the array:

{
  "dns": ["...", "8.8.8.8"]
}

and restart docker.

Also, could you try with the latest image? There was a change where startup is faster as the dependant images are pre-built

I've just tested with Ubuntu 18.04.1 LTS, docker version 18.06.1-ce, build e68fc7a and both the oc-cluster-up and the test above works without changing any DNS.

Apparently Docker-CE can handle correctly the fact that ubuntu uses dnsmaq, where /etc/resolv.conf has only a local DNS and the real nameserver is located in /run/systemd/resolve/resolv.conf.

Please make sure to use the docker version above and open a new issue if the problem persists.
