Deployment of TIBCO Order Management on Kubernetes

You can containerize the TIBCO Order Management application in Docker and then deploy it on the Kubernetes cluster. To containerize the application, you must build and run the Docker images by using the bundled Dockerfile. The deployment uses Kubernetes concepts such as, deployment, pod, kubectl, kubernetes service. For more details, see Kubernetes Documentation.

Building Docker Images

Preparation for the deployment starts with building Docker images using the Dockerfiles. The $OM_HOME/docker directory contains subdirectories with the ready-to-use Dockerfile and other scripts required to build the images. Detailed instructions on how to use the Docker file and build the image are provided in the respective Docker file and the Readme located at the same location. See the "Docker" section in the TIBCO® Order Management Administration guide for more details.

Deployment on Kubernetes

After creating the Docker files you must push them in the Docker registry so that they can be accessed by Kubernetes deployment. Kubernetes scripts are available at the $OM_HOME/kubernetes directory.

Example

The following example includes a snippet of the kubernetes-deploy-run-catalog-service.yml file:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: catalog-service
  labels:
    app: catalog-service
spec:
    replicas: 1
    selector:
        matchLabels:
            app: catalog-service
    template:
        metadata:
            name: catalog-service
            labels:
                app: catalog-service
        spec:
            containers:
            - name: catalog-service
              image: tibco/catalog-service:5.1.0
              ports:
              - containerPort: 9092
---
apiVersion: v1
kind: Service
metadata:
  name: catalog-service-service
spec:
    selector:
        app: catalog-service
    ports:
        - port: 9092
          targetPort: 9092
          nodePort: 30004
    type: LoadBalancer

Procedure

Run the following command on worker node (in master-worker kubernetes cluster setup) to create TIBCO Order Management Catalog deployment and service:

CMD>kubectl apply -f D:/Folder_Path/kubernetes-deploy-run-catalog-service.yml

The deployment.apps/catalog-service and service/catalog-service-service folders are created.
To check the container status, run the following commands:

- kubectl get all

- kubectl get pods

Note: The Running status indicates that a container is running without any issues.
To check logs inside the container, run the following command: CMD>kubectl exec -it Podname -- bash

Example:kubectl exec -it catalog-service-755fb5f69c-jch2s -- bash

When the catalog pod is up and running, users can access the Swagger-UI by accessing endpoints exposed for the service.

Example:http://EXTERNAL-IP:9092/swagger-ui.html
To delete deployment and service, run the following command:

CMD> kubectl delete -f D:/Folder_Path /kubernetes-deploy-run-catalog-service.yml

The deployment.apps "catalog-service" and service "catalog-service-service" folders are deleted.

Note: Similar steps are applicable for all services.
