Odo push fails on 3.11 cluster having docker version (18.06.0-ce) running on travis xenial distro

/kind bug

What versions of software are you using?

Operating System:
All supported

Output of odo version:
master

How did you run odo exactly?

Running tests jobs on travis CI

Actual behavior

Hitting error https://travis-ci.com/github/openshift/odo/jobs/324857465#L582 and some more different errors in the test running on openshift 3.11 with xenial distro of travis CI.

I am suspecting oc cluster up is having compatibility issue with the default docker available on xenial distro causing error like i mentioned above.

Expected behavior

Tests associated with openshift should also run on xenial distro of travis CI.

Any logs, error output, etc?

Xenial distro of travis CI is required to run latest kubernetes cluster. On the other hand we can use older version of minikube but odo push throws error in version of minikube, which has been elaborated in issue : #2928 .

However there are some other consequences also of using older version of minikube like lag of latest feature implementation and I am suspecting this could be one of the reason that odo push is not working as expected on older version of minikube. IMO we should move towards latest version minikube and hence xenial distro of travis CI could be one of the solution.

Currently we are running our test on travis CI with trusty distro, ubuntu version 14.04. And running the latest minikube needs systemd which was added in ubuntu 16.04, therefore we need to bump the ubuntu version to 16.04+ using xenial distro of travis CI.

So, i think we need to think for docker version on xenial distro of travis CI. The default docker version available in Xenial has incompatibility issue with 3.11 cluster i guess. Also i will try same app deployment using oc just to confirm the incompatibility issue.

Default docker version on Xenial distro

Will check with other docker version on Xenial distro. If it works then will stick to that version.

@prietyc123 you might need to configure docker daemon to allow unsecured registry on 172.30.1.1:5000

Ahh... Thanks for the tips. I will try it out for sure 👍

In ubuntu xenial configuring docker daemon /etc/docker/daemon.json with insecure registry "insecure-registries": ["172.30.0.0\/16"] worked fine for oc cluster up
