Deploying on the Kubernetes cluster

IBM® Product Master services are deployed on the Kubernetes cluster by using operators.

Proceed as follows for volume creation when deploying on the local cluster.

1. Create directories for volumes with required directory structure and proper permissions on every node on Kubernetes cluster by using the following command.

   mkdir <parent directory>
   cd <parent directory>
   mkdir appsrv
   mkdir ftsindlog
   mkdir ftspimlog
   mkdir gds
   mkdir ml
   mkdir mongodb
   mkdir mongodblog
   mkdir mq-data
   mkdir newui
   mkdir sch
   mkdir wfl
   mkdir dam
   chmod +777 <parent directory> -R
   e.g. mkdir -p /mnt/ipm12/
   cd /mnt/ipm12/
   mkdir appsrv
   mkdir ftsindlog
   mkdir ftspimlog
   mkdir gds
   mkdir ml
   mkdir mongodb
   mkdir mongodblog
   mkdir mq-data
   mkdir newui
   mkdir sch
   mkdir wfl
   mkdir dam
   chmod +777 /mnt/ipm12/ -R
   

   Note: You need to share the local directory for the DAM volume /dam among cluster nodes by using the Network File System (NFS) service.
2. Create volumes by using the following command.

   kubectl apply -f volumes.yaml

3. View the created volumes by using the following command.

   kubectl get pv

4. Create namespace by using the following command.

   kubectl create ns ipm

5. Modify the operator.yml file to update operator registry, image, and version (to point to the local registry). Do not modify other files.
   1. Update the line image: <local_registry_name>/ipm-operator:12.0.2 with the local registry
6. Deploy the operator by using the following command.

   kubectl apply -f ipm.psl.com_ipms_crd.yaml
   kubectl apply -f role_binding.yaml        
   kubectl apply -f role.yaml                
   kubectl apply -f service_account.yaml
   kubectl apply -f operator.yaml
   

   • The custom resource ipm-12.0.2_cr.yml file contains application deployment specification.
   • While editing the CR, replace xxxxx with wanted value and replica count as required.
7. Deploy the Product Master, by using the following command.

   kubectl apply -f  ipm-12.0.2_cr.yml

8. View all resources by using the following command.

   kubectl get all -n ipm

9. View specific resources by using the following command.

   kubectl get <pods/deploy/svc/pvc/cm/pv> -n ipm

   Example

   kubectl get pods -n ipm

10. Check logs for a specific pod by using the following command.

    kubectl logs -f <pod name> -n ipm

11. To uninstall by using the following command.

    kubectl delete -f ipm-12.0.2_cr.yml 
    kubectl delete -f operator.yaml             
    kubectl delete -f role_binding.yaml         
    kubectl delete -f role.yaml                 
    kubectl delete -f service_account.yaml 
    kubectl delete -f volumes.yaml 
    kubectl delete -f ipm.psl.com_ipms_crd.yaml 
    kubectl delete ns ipm
