scripts/oc-cluster-up.sh not working on centos7 and ubuntu 18.04

Hello together,
I am currently trying to get the aerogear environment set up with oc cluster up. I tried the installer now in different ways. First approach like described in the README on this site with the master branch and also the way for the old 2.0.0 release like described here:

https://docs.aerogear.org/aerogear/Native/getting-started-installing.html

Unfortunately without success yet. I like to focus an the master branch in the following. Here is the output of the installer when used on a fresh centos minimal install. I also included ansible and net-tools packages.
I always see the same behavior "Wait for IDM DB pod to be ready" times out. When I look into the namespace mobile-developer-services, I see that the keycloak pod was successfully deployed and that sso-postgresql failed.

Can anyone provide directions here what I am doing wrong or how I can work around the issue?

```
