Binding BusinessWorks Application to Monitoring Application on Kubernetes

You can bind TIBCO BusinessWorks Container edition application.

1. Tag the application docker image by running the following command:

   docker tag <application_image_name> your_docker_container_registry/<your_project_name>/<application_image_name>
   
   

2. Push your application image to the Docker Container Registry.
   For example: To push your application docker image on Google Cloud Registry, run the following command:

   gcloud docker -- push gcr.io/<your_project_name>/<application_image_name>
   
   

3. Confirm that the image is present in the Docker Container Registry.
4. Create the manifest.yml file and update the application image name. Ensure that the image name follows the following format:

   <your_docker_container_registry>/<your_gcloud_project_name>/<image_name>
   
   

   To configure monitoring application with external database, add the following two environment variables to the manifest file and port 80 with monitoring URL.

   • BW_APP_MONITORING_CONFIG
   • BW_JAVA_OPTS

   The below is a sample of the manifest.yml file:

   apiVersion: v1
   kind: Service
   metadata:
     name: <BW_APP_IMAGE_NAME>
     labels:
       app: <BW_APP_IMAGE_NAME>
   spec:
     type: LoadBalancer
     ports:
     - port: 80
       targetPort: 8080
     selector:
       app: <monitoring_image>
   ---
   apiVersion: v1
   kind: ReplicationController
   metadata:
     name: <BW_APP_IMAGE_NAME>
   spec: 
     replicas: 1
     selector:
       app: <BW_APP_IMAGE_NAME>
     template:
       metadata:
         name: <BW_APP_IMAGE_NAME>
         labels:
           app: <BW_APP_IMAGE_NAMEe>
       spec:
         containers:
           - name: <BW_APP_IMAGE_NAME>
           image: gcr.io/<PROJECT_ID>/<BW_APP_IMAGE_NAME>
           resources:
             limits:
                memory: 512Mi
             requests:
                memory: 512Mi
           imagePullPolicy: Always
           env:
           - name: BW_PROFILE
             value:default
           - name: BW_LOGLEVEL
             value: DEBUG
           - name: BW_APP_MONITORING_CONFIG
             value: '{"url":"http://<MONITORING_IP>:80"}'
           ports:
             - containerPort: 8080

   Note: To bind your TIBCO BusinessWorks™ Container Edition application to monitoring running on HTTPS server, add the pertaining URL in the BW_APP_MONITORIN_CONFIG property
5. To create the monitoring service and replication controller, run the following command:

   kubectl create -f manifest.yml
   
   

6. To verify that the application has started successfully, run the following command:

   kubectl logs pod-name
   

7. To get the external IP of running monitoring service, run the following command:

   kubectl get svc

   Access the monitoring dashboard in the browser by using the external IP.
