This article is provided as a technical guide to set up Joget DX 8 with PostgreSQL database on Kubernetes. The following steps were implemented on Ubuntu 22.04, please modify the commands to suit your environment.


Deploy PostgreSQL on K8s using Helm

# deploy postgresql using Helm
helm install postgres oci://registry-1.docker.io/bitnamicharts/postgresql
helm list
helm get notes postgres

# wait for postgresql to startup
kubectl wait \
  --for=condition=ready pod \
  --selector=app.kubernetes.io/name=postgresql \
  --timeout=180s

Create PostgreSQL Database

# check for postgresql password
export POSTGRES_PASSWORD=$(kubectl get secret --namespace default postgres-postgresql -o jsonpath="{.data.postgresql-password}" | base64 --decode)

# run psql
kubectl run postgres-postgresql-client --rm --tty -i --restart='Never' --namespace default --image docker.io/bitnami/postgresql:16.3.0-debian-12-r4 --env="PGPASSWORD=$POSTGRES_PASSWORD" \
      --command -- psql --host postgres-postgresql -U postgres -d postgres -p 5432

$ CREATE DATABASE jwdb;
$ \quit

Import Joget DB SQL

Obtain the pgsql file from Configure for PostgreSQL.

# import sql
cat jwdb-postgres.sql | kubectl exec -i postgres-postgresql-0 -- env PGPASSWORD=$POSTGRES_PASSWORD psql -U postgres -d jwdb

Deploy Joget

Follow the instructions in Joget on Kubernetes.

Configure Joget Datasource for PostgreSQL

# ssh into tomcat pod and create datasource files
kubectl exec --stdin --tty deployments/joget-dx8-tomcat9 -- /bin/bash

$ cat <<EOF > /opt/joget/wflow/app_datasource-postgresql.properties
workflowUser=postgres
workflowPassword=REPLACE_POSTGRES_PASSWORD_HERE
workflowDriver=org.postgresql.Driver
workflowUrl=jdbc\:postgresql\://postgres-postgresql/jwdb
EOF

$ cat <<EOF > /opt/joget/wflow/app_datasource.properties
currentProfile=postgresql
EOF

$ exit

Restart Joget

# restart pods

kubectl scale --replicas=0 deployment/joget-dx8-tomcat9

kubectl scale --replicas=1 deployment/joget-dx8-tomcat9

# view logs

kubectl logs -f deployment/joget-dx8-tomcat9
