This blog post provides an overview of various topics related to Red Hat OpenShift on IBM Cloud in a virtual private cloud environment I created. I have organized this overview into three main topics.

New Open-Source Multi-Cloud Asset to build SaaS
When software is provided as a managed service (SaaS), using a multi-tenant approach helps minimise costs for the deployments and operations of each tenant. In order to leverage these advantages, applications need to be designed so that they can be deployed to support multiple tenants, while maintaining isolation for security reasons. At the same time, common deployment and operation models are required so that new SaaS versions can be deployed to existing tenants, or to onboard new tenants, in a reliable and efficient way.
An alternative way for last blog post called “Use a Ngnix load balancer on a VSI to access an application on OpenShift in VPC”¶
alancer on the Virtual Service Instance (VSI) from the last blog post titled Use a Ngnix load balancer on a VSI to access an application on OpenShift in VPC.
Open the door for root users in Red Hat OpenShift (example StatefulSet)¶
This "blog post"/"cheat sheet" is about "Open the door for root users in OpenShift (example StatefulSet)". The topic is in context of two blog posts I wrote called Run a PostgreSQL container as a non-root user in OpenShift and Open the door for root users in Red Hat OpenShift¶.
Open the door for root users in Red Hat OpenShift (example Deployment)¶
This "blog post"/"cheat sheet" is about "Open the door for root users in OpenShift". The topic is in context of an older blog post I wrote called Run a PostgreSQL container as a non-root user in OpenShift. Let's look for the opposite perspective this blog post.
Automated creation of a Red Hat OpenShift cluster on IBM Cloud using the existing CLIs and plugins
This blog post is about automating the creation of a Red Hat OpenShift cluster on IBM Cloud in a Virtual Private Cloud. I used bash scripting with the IBM Cloud CLI and and the associated IBM Cloud CLI plugins vpc-infrastructure and kubernetes-service. I also use jq to handle json output.
Create an edge route for an example application on a Red Hat OpenShift Cluster on IBM Cloud
the content, with some small modifications, to my existing example application. It's the same application I used in this blog post Using the internal OpenShift container registry to deploy an application.
Start with CICD using the Cloud Native Toolkit from the IBM Garage
Today's blog post is about the awesome IBM Garage Cloud Native Toolkit to support continuous integration and continuous delivery (CICD).
How to configure the IBM Cloud Operator for an existing Cloudant service?
That example shows how to bind an existing Cloudant service instance in IBM Cloud to an application running in Red Hat OpenShift.
Write your first simple Kubernetes Operator
Even a student with minimal knowledge of Kubernetes should be able to install a highly complex container-based application on top of Kubernetes or OpenShift. Eliminate the manual interaction effort as much as possible to deploy, run, and maintain your containerized application on Kubernetes or OpenShift with your Operator implementation.
