Introduction

Ortec Finance conducts a research towards High Performance Cloud Computing. This repository contains prototypes of synchronous and asynchronous cloud applications.

Prerequisites

Cluster related:

1. RedHat Openshift 4.X
2. KEDA operator for Openshift.
3. Red Hat Integration - AMQ Broker for RHEL 8 (Multiarch) operator Openshift.
4. Serverless operator for Openshift.
5. KEDA instance in "keda" namespace.
6. KNativeServing instance in "knative-serving" namespace.

Local machine:

1. oc cli tool
2. kustomize
3. Docker / Podman

Keep base as an abstraction of the deployment. All the changes for your deployment can be done via Kustomize.

Deploy

1. Navigate to the ../{PrototypeName}/gitops/overlays/{develop or main}/
2. Open kustomization.yaml
3. Replace the indicated values with your URL/Namespace etc.
4. Save.
5. oc apply -k .

Build

If you want to modify the code an build your own image

1. Navigate to the ../{PrototypeName}/{ProjectName}
2. docker build -rm -t {IMAGE_NAME:IMAGE_TAG}
3. docker push {IMAGE_NAME}
4. Navigate to the ../{PrototypeName}/gitops/overlays/{develop or main}/kustomize.yaml
5. Change images/newName to {IMAGE_NAME}
6. Change images/newTag to {IMAGE_TAG}
7. Save.
8. oc apply -k .
