Running an Application with Shared All Storage

• For the shared all persistence, configure a database server and define a storage for its database. For example, you can use a MySQL server for database connections. To implement the database, you can use the mysql container from the Docker hub. Provide the database connection details in the cache and inference agent configuration files. Define a Storage Class respective to cloud provider for storage class provisioner to provision storage (persistent volume claim) for the MySQL database.

• For this deployment, the sample YAML files are available at BE_HOME->cloud->kubernetes->cloud_name->cache->shared-all.

1. Create the Kubernetes object specification (.yaml) files based on your deployment requirement.

   For details about describing a Kubernetes object in a YAML file, see Kubernetes documentation.

• For AWS cluster deploy the files

  kubectl create -f db-configmap.yaml
  

• For PKS cluster deploy the files

  kubectl create -f db-configmap.yaml
  

• For Azure cluster deploy the files

  • azure db

  kubectl create -f db-configmapdocker.yaml
  

  • azure mysqldockerimage

  kubectl create -f db-configmapmysql.yaml
  kubectl create -f mysql.yaml
  kubectl create -f mysql-service.yaml
  

• For OpenShift deploy the files

  kubectl create -f db-configmap.yaml
  kubectl create -f mysql.yaml
  kubectl create -f mysql-service.yaml
  kubectl create -f persistent-volume-and-claim.yaml
  

• For minikube deploy the files

  kubectl create -f db-configmap.yaml
  kubectl create -f mysql-service.yaml
  kubectl create -f persistent-volume.yaml
  kubectl create -f Statefulsets-mysql.yaml
  

• For example, create the following Kubernetes objects by using the sample YAML files mentioned in Sample Kubernetes YAML Files for Applications with Shared All Persistence.

  
  
  
  kubectl create -f bediscoverynode.yaml
  
  kubectl create -f bediscovery-service.yaml
  
  kubectl create -f becacheagent.yaml
  
  kubectl create -f beinferenceagent.yaml
  
  kubectl create -f befdservice.yaml
  

2. (Optional) If required, you can check logs of TIBCO BusinessEvents pod.

   Syntax:

   kubectl logs <pod>
   

   For example, use the kubectl get command to get the list of pods and then use the kubectl logs command to view logs of becacheagent.

   kubectl get pods
   
   kubectl logs becacheagent-86d75d5fbc-z9gqt
   

3. Get the external IP of your application, which you can use to connect to the cluster.

   Syntax

   kubectl get services <external_service_name>
   

   For example,

   kubectl get services befdservice
