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

Access the OpenShift Web Console and login

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

Step 2: Deploy MySQL Database

Under the selected project, select +Add > Database and select MySQL, then Instantiate Template.

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


Step 3: Deploy Joget Certified Container Image

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.

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 > Container Image and click on 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


Once the secret has been created, select the Image Name option and key in registry.connect.redhat.com/joget/joget-dx7-eap7. Key in the desired Application Name and Name.


Image Name

registry.connect.redhat.com/joget/joget-dx7-eap7

Name

joget-dx7-eap7


Step 4: Configure Persistent Storage

The next step is to add persistent storage to the container for storing configuration files and persistent file uploads.  Under Topology, select the Deployment. Select Add Storage under the Actions menu.

In the Add Storage page under Persistent Volume Claim, select Create new claim and fill in desired values then Save.



Name

joget-dx7-eap7-claim

Access Mode

Shared Access (RWX)

Size

10GB (or as required)

Mount Path/home/jboss/wflow



Step 5: Configure for Clustering and Licensing

Using the OpenShift command line interface (CLI), run the following commands to enable clustering and licensing.


export PROJECT_NAME=demo # modify this to suit your project name
export APP_NAME=joget-dx7-eap7 # modify this to suit your app name

echo === configure jboss clustering ===
oc set env deployment/${APP_NAME} JGROUPS_PING_PROTOCOL=openshift.DNS_PING -e OPENSHIFT_DNS_PING_SERVICE_NAME=${APP_NAME}-ping -e OPENSHIFT_DNS_PING_SERVICE_PORT=8888 -e CACHE_NAME=http-session-cache
oc expose deployment/${APP_NAME} --port=8888 --name=${APP_NAME}-ping --cluster-ip=None

echo === assign cluster role view permission for the project service account (to read deployment info for licensing) ===
oc create clusterrolebinding default-view --clusterrole=view --serviceaccount=$PROJECT_NAME:default --namespace=$PROJECT_NAME



Once the pods in the deployment have finished starting up, access the Deployment under Topology to see the running pods. You will also see a Route created for it, so click on the Location URL to access Joget.



Deploy Joget using the OpenShift CLI

The following is a Linux script to accomplish a similar Joget platform deployment using the  OpenShift command line interface (CLI). 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

#!/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-dx7-eap7
export IMAGE_TAG=latest
export APP_NAME=joget-dx7-eap7
export DB_APP_NAME=jogetdb
export STORAGE_NAME=joget-data
export MYSQL_DATABASE=jwdb
export MYSQL_USER=joget
export MYSQL_PASSWORD=joget

echo === deploy Joget on OpenShift ===
echo PROJECT_NAME: $PROJECT_NAME
echo REGISTRY_SERVER: $REGISTRY_SERVER
echo REGISTRY_USERNAME: $REGISTRY_USERNAME
echo REGISTRY_EMAIL: $REGISTRY_EMAIL
echo IMAGE_NAMESPACE: $IMAGE_NAMESPACE

echo MYSQL_DATABASE: $MYSQL_DATABASE
echo MYSQL_USER: $MYSQL_USER

echo === create project ===

echo === deploy MySQL ===
oc new-app openshift/mysql:8.0 --name $DB_APP_NAME -e MYSQL_USER=$MYSQL_USER -e MYSQL_PASSWORD=$MYSQL_PASSWORD -e MYSQL_DATABASE=$MYSQL_DATABASE
 
echo === create and bind secret to pull Joget image ===
oc create secret docker-registry $REGISTRY_SERVER --docker-server=$REGISTRY_SERVER --docker-username=$REGISTRY_USERNAME --docker-password=$REGISTRY_PASSWORD --docker-email=$REGISTRY_EMAIL
oc secrets link default $REGISTRY_SERVER --for=pull
 
echo === assign cluster role view permission for the project service account to read deployment info for licensing ===
oc create clusterrolebinding default-view --clusterrole=view --serviceaccount=$PROJECT_NAME:default --namespace=$PROJECT_NAME
 
echo === create joget deployment, service and persistent volume claim ===

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


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

 

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
