Example Frontend/Backend deployment

Creates a DeploymentConfig, Service, and ImageStream for a frontend and backend application. Sets up a PostgresDB. And Puts the services behind an OAuth proxy using Keycloak as a security realm.

Also sets up a Tekton pipeline

Prerequisites:

• Local Installation of Helm 3
• Openshift 4 cluster
• Openshift Pipelines

Note: You will also need to update the global.cluster.baseDomain inside of our values.yaml file to be the domain name of your Kubernetes cluster. _{This can be found using your openshift console url. I.E. if your console url is https://console-openshift-console.apps.cluster-99df.99df.sandbox1911.opentlc.com/ than your domain name would be `apps.cluster-99df.99df.sandbox1911.opentlc.com}

Application Architecture

Today we will be deploying a basic “Todo List” application consisting of the following:

• React Frontend
• SpringBoot Backend
• Postgres Database
• oAuth 2 proxy
• Keycloak Security Realm

All of the Kubernetes resources will be created using Helm 3, and the application containers will be built and deployed with a basic Openshift Pipeline setup.

Install the Helm Chart

Update Helm Dependencies

helm dependency update

Run Helm Install

First validate that the global.cluster.basedomain inside of the

helm install <RELEASE_NAME> .

Update Helm Chart to newer version

Update appVersion in the Chart.yaml file

helm upgrade <RELEASE_NAME> .
