Not sure which Red Hat OpenShift subscription offering is right for you? It can be a little overwhelming with so many options available, but we're here to tidy things up. This episode we’re joined by Tushar Katarki, Product Manager for OpenShift, to explore the differences between OpenShift subscription levels. 

Whether self-managed, fully managed, on-premises, on private cloud, public cloud, or edge deployment - all editions of Red Hat OpenShift offer a consistent user experience for developers and operations across every footprint. RHOPP, RHOCP, RHOKE, and RHOSD? All the acronyms you've come to know and love will be broken down into simple language.

As always, please see the list below for additional links to specific topics, questions, and supporting materials for the episode!

Supporting links for today:

  • Just a friendly reminder to keep an eye on RHSB-2021-004 and be sure to update your cluster appropriately to mitigate!
  • We’ve talked about the install process and how to troubleshoot a few separate times, but I recently discovered there is a GitHub page, maintained by engineering, on the topic. This is another set of suggestions, beyond what’s in the docs, for how to figure out what went wrong during installation.
  • A few weeks back we talked about mounting /var to a different partition or disk when deploying RHCOS. There are some distinct advantages to doing this, not the least of which is being able to have a dedicated disk for container storage, but there are also some things to be on the lookout for too.
  • Another item we’ve talked about before (but I apparently did not catlog in a blog post) is the sizing of the cluster network and service network, which are configured at install time and used for Pods and Services. This segment of the show discusses how to determine the appropriate size of those subnets for your cluster.
