We installed all the prereqs. Than took the internetaccess away from our master
+ node and we started the playbook. It crashes here.

Can someone tell us what we're doing wrong?

Onderwerp: Re: Which openshift instances need a public IP
The short answer is that you don't need public IP addresses. You can have
everything running with private IPs.

Thanks for your reply. Just the main goal we want to obtain is to keep our
traffic from pod to pod (using routes, router, dns-wildcard) internal. So
performing al this stuf on a private IP. Is that possible?
I just checked this blog:
http://dustymabe.com/2016/12/07/installing-an-openshift-origin-cluster-on-fedora-25-atomic-host-part-1/#comment-42901
He is using public ip's + private ip's. Are the privates useful in this case?
We're able to use both and use and we can setup our own dns server but we don't
want that our routes are going outside of our cluster. In public and than going
back in the cluster.
So main goal: translations of routes through router should stay in the private
network.
Is that possible?
Thanks

Onderwerp: Re: Which openshift instances need a public IP
Hi Den,
you may need internet connectivity. Public IPs is not a requirement for that
(confer proxy and NAT). Another option is to install OpenShift disconnected.
See:
https://docs.openshift.com/container-platform/3.3/install_config/install/disconnected_install.html.
Disconnected Installation - Installing a Cluster
...<https://docs.openshift.com/container-platform/3.3/install_config/install/disconnected_install.html>
docs.openshift.com<http://docs.openshift.com>
An OpenShift Container Platform disconnected installation differs from a
regular installation in two primary ways:
Also, editing etc/hosts is not enough. You will require a proper DNS server
(dnsmasq for instance) as the containers don't use /etc/hosts of the host for
name resolution.
Regards,
Fr?d?ric

Hi,
We have our own Registry (like dockerhub) from where we can pull images. (the
registry is in the same private network 192.168.25.x).
Now we're trying to install OpenShift (very basic: 1 master + 1 node) on
192.168.25.1 and 192.168.25.2.
We have experience with those installs but than we used public ip's.
We have SSH acces from our master to our node.
But: prereqs: you need ansible on the master, git, docker on master and node,
...
- So initially we need public ip's on our servers to install those
prerequisitions?
- Do we need a public IP on every instance when we want to run the playbook?
(it failed for resolving something to check ik yum-utils were installed).
- Is this a good solution?: (public IP and private on master and node). Install
prereqs and execute playbook. So we have a cluster. After that deleting the
public network and reexecuting the playbook with only private ip's (or only a
public ip on the master). Will this work?
So as you can see we can use some input in using the setup.
We want that the traffic between our nodes goes internally. So we probably need
our own DNS server for hosts, routing, wildcards. (initially we try to cover
this in /etc/hosts).
If someone has experience with the setup of OpenShift where the communication
over routes (through the router) happends internally (so no public wildcard).
Please share some knowledge :).
