My first OpensShift (OpenShift Sample Architecture)

The My first OpenShift is a OpenShift sample architecture. This provides a set of manifest files for deploying microservices to OpenShift cluster with devops tools. You can deploy with only few steps with init.sh script.

⚠️ NOTICE: Most of this sample architecture and documents are still a work in progress.

Requirements

• OpenShift >= 4.x
• oc client >= 4.x

Quick Start

• Clone or download this repository
• Go inside of directory, cd my-first-openshift
• Run this command ./init.sh

Overview

This is an overview of the sample architecture.

Key tech stacks are:

Application / Middleware layer

Component	Stack	Deployment
Front end	React	-
Load balancer	-	OpenShift resource
Backend / Batch / Worker	Go / Node.js	k8s Deployment
RDB	Postgres	Crunchy PostgreSQL Operator
Document DB	MongoDB	MongoDB Enterprise Kubernetes
Object Storage	MinIO	MinIO Hybrid Cloud Object Storage
Queueing	Kafka	AMQ Streams
Workflow	Airflow	-

DevOps

Component	Stack	Deployment
Service mesh	Istio	Red Hat OpenShift Service Mesh
Tracing	Jaeger	Red Hat OpenShift distributed tracing platform
Monitoring	Prometheus / Grafana	-
Logging	Elasticsearch / Fluentd / Kibana	-
CI	Tekton	RedHat OpenShift Pipelines
CD	ArgoCD	Red Hat OpenShift GitOps

Resources

OpenShift and kubernetes resources are deployed as follows.
