Customer of openshift/kubernetes which uses NFS as there persistent volume type want sometimes to change the mount options.

A lot of enterprise companies have there own CA and PKI . The main issue on a own Cloud Infrastructure like kubernetes and openshift is to distribute the CA on every machine.

You will find here some all day work tips for OpenShift Cluster this tips works also for the origin version.

As you can read in my blog post about syslog in a container world it isn’t easy to run a syslogger in a none privileged Container which is the default setup on openshift.

I describe here how you can setup a syslog receiver for the openshift router which is possible since the version 3.3 via Router Environment Variables.

The main reason why this blog post exist is that OpenShift V3 and Kubernetes is very close binded to port 8443. This could be changed in the future.

UPDATE: Since OpenShift Enterprise 3.4 are both ports openshift_master_api_port and openshift_master_console_port documented Configuring Master API and Console Ports.

I used several times a dedicated haproxy pod to provide access to the OpenShift v3 Web console and api on port 443 (https).

This concept could also be used for different services in the PaaS which are able to talk via SNI.
