Red Hat OpenShift is a container application platform that brings Docker and Kubernetes to the enterprise. As a cloud native computing platform, OpenShift allows teams to automate the build, deployment, and management of applications. They can focus on developing apps without worrying about the underlying infrastructure, whether on physical/virtual servers, or on public/ private/hybrid cloud environments.

 As an open source no-code/low-code platform to visually build enterprise web apps for coders and non-coders, Joget is an ideal complement to OpenShift to fill the gap. The Joget platform is now available as a Red Hat Certified Container, so it is trusted, secure and commercially supported on OpenShift. This article describes the steps in deploying the certified Joget container image running with the MySQL database.

    

Deploy Joget using the OpenShift Web Console

Step 1: Create OpenShift Project

Create a project using the Create Project button and key in the desired Name, Display Name and Description.

Step 2: Deploy MySQL Database

Under the selected project, select Add to Project > Browse Catalog and select the MySQL image.

Key in the appropriate settings and click on Create e.g.

Step 3: Deploy Joget Platform

To access the Red Hat Container Catalog, a valid username and password that is used to log in to the Red Hat Customer Portal are required.

Under the selected project, select Add to Project > Deploy Image and click on the create an image pull secret link. In the ensuing popup, key in the Red Hat login details for the registry.

Once the secret has been created, select Add to Project > Deploy Image, select the Image Name option and key in registry.connect.redhat.com/joget/joget-v6-enterprise. Click on the small search icon to load the image details from the registry, key in the desired Name then click Deploy.

Step 4: Add Persistent Storage

The next step is to add persistent storage to the container for storing configuration files and persistent file uploads.  Under Applications > Deployments, select the application, then the Configuration tab. Scroll down to the Volumes section and click on the Add Storage link.

In the Add storage page, click on the small create storage link. Create the new storage with the desired values e.g.

Back in the Add Storage page, select the newly created storage, set the Mount Path to /opt/joget/wflow, then Add.

Step 5: Create Service Route for External Access

At this point, the service is not accessible from an external web browser so you will need to create a route, which exposes a service at a host name.

Click on Applications > Services and select joget-v6-enterprise.

Select Actions > Create Route, set the Path to /jw and click on Create.

Return to the Overview and click on the URL next to the application name to launch the Joget platform.

Deploy Joget using the OpenShift CLI

For those more inclined to use a non-graphical command line interface, it is actually faster to use the OpenShift command line interface (CLI) to deploy the Joget platform.

The following is a Linux script to accomplish a similar Joget platform deployment. Before running this script, install the CLI and login. Change the environment variables in the script accordingly, at least the four values below:

#!/bin/sh

export PROJECT_NAME=joget-openshift
export REGISTRY_USERNAME=email@domain
export REGISTRY_PASSWORD=password
export REGISTRY_EMAIL=email@domain
export REGISTRY_SERVER=registry.connect.redhat.com
export IMAGE_NAMESPACE=joget
export IMAGE_NAME=joget-v6-enterprise
export IMAGE_TAG=latest
export APP_NAME=joget-v6-enterprise
export DB_APP_NAME=joget-mysql
export STORAGE_NAME=joget-data
export MYSQL_DATABASE=jwdb
export MYSQL_USER=joget
export MYSQL_PASSWORD=joget

Setup Database

The first time the Joget platform is accessed, the Database Setup page will be displayed. Configure the database settings using the values defined when deploying the MySQL database previously e.g.

Upon successful configuration, the Joget App Center will be loaded.
