Deploying a monitoring application on Kubernetes

You can deploy an monitoring application on kubernetes with an external database.

Before you begin

Ensure that you have configured the database for application monitoring.
Ensure that you have created the TIBCO BusinessWorks™ Container Edition base docker image. For more information about creating base docker image, see Creating TIBCO BusinessWorks Container Edition base docker image in the Application Development guide.
Ensure that you have created the TIBCO BusinessWorks™ Container Edition application docker image. For more information about building application docker image, see Building the application docker image in the Sample guide.

Procedure

Tag the application docker image by running the following command:

docker tag <application_name>your_docker_container_registry/<your_project_name>/<application_name>

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_name>
```
Confirm that the image is present in the Docker Container Registry.
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.
To create the monitoring service and replication controller, run the following command:
```
kubectl create -f manifest.yml
```
To verify that the application has started successfully, run the following command:
```
kubectl logs pod-name
```
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.
