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.

) is an application hosting platform by Red Hat (www.redhat.com) that makes it easy to run container-based web applications in the cloud. As an open source no-code/low-code platform to easily visually build enterprise web apps for cloud coders and mobile, Joget Workflow (www.joget.org) is a good complement for OpenShift.

Info

OpenShift Online has a free monthly plan that allows you to host up to 3 web applications in the cloud for free. As such, you can run a basic Joget Workflow deployment without any cost!

This article describes the steps required to deploy Joget Workflow on OpenShift Online using an Ubuntu Linux client. Just follow the steps below and you can get a running Joget Workflow installation very quickly. You can also manage OpenShift using other OS platforms (e.g. Windows, OSX, etc) by adapting the commands accordingly.

Step 1: Signup for OpenShift

Sign up for free at https://www.openshift.com/app/account/new and follow the instructions

Step 2: Install Prerequisites i.e. Git, Ruby and OpenShift Client Tools

Run the following commands in your Ubuntu client to install the prerequisite tools to manage OpenShift applications:

Code Block
languagebash
# install git and ruby
echo === Install Git and Ruby ===
sudo apt-get install git ruby

# install openshift client tools
echo === Install OpenShift Client Tools ===
sudo gem install rhc

# run openshift setup
echo === Run OpenShift Setup ===
rhc setup

Step 3: Create OpenShift App and Deploy Joget Workflow

Run the following script in your Ubuntu client to create an OpenShift application and install Joget Workflow v5 Enterprise Edition:

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

Access the OpenShift Web Console and login

Image Added

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

Image Added

Step 2: Deploy MySQL Database

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

Image Added

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

 

Namespace

openshift

Database Service Name

jogetdb

MySQL Connection Username

joget

MySQL Connection Password

joget

MySQL Database Name

jwdb

 

Image Added

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 is required.

Info

If you do not have an account, you can acquire one by registering for one of the following options:

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.

 

 

Secret Name

registry.connect.redhat.com

Authentication Type

Image Registry Credentials

Image Registry Server Address

registry.connect.redhat.com

Username

Red Hat account username

Password

Red Hat account password

Email

Red Hat account email

Link secret to a service account

Yes

Service Account

default

 

Image Added

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.

 

 

Image Added

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.

Image Added

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

 

Name

joget-data

Access Mode

Shared Access (RWX)

Size

1GB (or as required)

 

Image Added

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

 

 

Mount Path

/opt/joget/wflow

 

Image Added

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.

Image Added

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

 

Path

/jw

 

Image Added

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:

 

PROJECT_NAME

The desired project name

REGISTRY_USERNAME

Red Hat account username

REGISTRY_PASSWORD

Red Hat account password

REGISTRY_EMAIL

Red Hat account email

Code Block
languagebash
#!/bin/sh

Step 4: Access Joget Workflow installation

Deployment may take some time so be patient, check the OpenShift app logs using:

Code Block
languagebash
rhc tail -a $APP_NAME
> pvc.yaml
apiVersion: "v1"
kind: "PersistentVolumeClaim"
metadata:
name: "$STORAGE_NAME"
spec:
accessModes:
  - "ReadWriteMany"
resources:
  requests:
    storage: "1Gi"
EOF
oc create -f pvc.yaml
rm pvc.yaml

echo === mount storage ===
oc set volume dc/$APP_NAME --add --type=persistentVolumeClaim --claim-name=$STORAGE_NAME --mount-path=/opt/joget/wflow

echo === expose service route for external excess ===
oc expose svc $APP_NAME --path=/jw
oc annotate route $APP_NAME --overwrite haproxy.router.openshift.io/timeout=60s
oc get route
echo URL: http://$(oc get route $APP_NAME --template='{{ .spec.host }}')/jw


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.

 

Database Host

jogetdb

Database Port

3306

Database Name

jwdb

Database User

joget

Database Password

joget

 

Image Added

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

Warning

NOTE: If you encounter a 504 Gateway Timeout during the database setup, it is caused by the database initialization taking longer than the default OpenShift Route timeout. You can actually ignore the error and wait a couple of minutes before accessing the Application URL from the Overview page again.

You can also increase the route timeout using the OpenShift CLI i.e.

oc annotate route $APP_NAME --overwrite haproxy.router.openshift.io/timeout=60s
