OpenShift Production Platform

Production OpenShift cluster implemented on VMware vCenter in a disconnected environment.

01

Context

A production OpenShift environment was implemented on VMware vCenter within a disconnected environment.

02

Role

Architecture was provided by the designated Architect. My responsibility was the end-to-end implementation of the environment based on that design.

This involved VM creation, bastion-based SSH access, bootstrap sequencing, cluster node integration, and ensuring production readiness.

Implementation

01

Virtual Machine Provisioning

Created the virtual machines required for the cluster.

02

Bastion Access

Established SSH access through the bastion environment.

03

Bootstrap

Executed the OpenShift bootstrap process.

04

Master Integration

Added the Master nodes to the cluster.

05

Worker Integration

Added the Worker nodes.

06

Production

Validated the resulting environment and brought the cluster into Production.

05

Challenge: Disconnected Environment

The project required implementation in an environment without normal external connectivity.

06

Resolution

Resolved through extensive technical documentation research, investigation, troubleshooting, and validation.

07

Outcome

Successfully brought the OpenShift environment into Production and established an operational 3-Master / 3-Worker cluster.

Engineering Lessons

01

Production implementation requires translating architecture into an operational environment.

02

Infrastructure implementation involves more than provisioning resources; access, sequencing, validation, and integration matter.

03

Disconnected environments increase the importance of documentation, investigation, and validation.

04

Clear separation between architecture ownership and implementation ownership is important.

05

A production platform should be presented through evidence and operational responsibility rather than unsupported expertise claims.
