Building and Configuring DES

This section explains the steps to build and configure DES.

To build and configure DES,

1. Execute the following steps to download the DES images,
   1. Download the image archives.

      

   2. Connect to the podman machine through ssh and run the loading command.

      sudo podman load --input [archive names]

      Sample load commands:

      sudo podman load --input des-event-processor-latest.tar

      sudo podman load --input des-config-installer-latest.tar

      sudo podman load --input des-event-cleanup-latest.tar

      sudo podman load --input des-event-pull-adapter-latest.tar

      sudo podman load --input des-event-router-latest.tar

      sudo podman load --input des-grafana-latest.tar

      sudo podman load --input des-prometheus-latest.tar

      sudo podman load --input des-demo-webapp-kafka-latest.tar

      sudo podman load --input cp-schema-registry.tar

      sudo podman load --input cp-kafka.tar

      sudo podman load --input des-tool-latest.tar

      sudo podman load --input cp-zookeeper.tar

   3. Run the below command to list the images loaded.

      Sudo podman images

      

2. Execute the commands to tag the DES images as show below.

   Docker image command tag [IMAGE ID] [repository]/[image name]:[TAG]

   Repository, image name, and TAG should be the version of the DES pack (for example, 21.0.6)

   Sample commands:

   sudo podman image tag localhost/des-event-processor:latest repository/des-event-processor:latest

   sudo podman image tag localhost/des-config-installer:latest repository/des-config-installer:latest

   sudo podman image tag localhost/des-event-cleanup:latest repository/des-event-cleanup:latest

   sudo podman image tag localhost/des-event-pull-adapter:latest repositoryu/des-event-pull-adapter:latest

   sudo podman image tag localhost/des-event-router:latest repository/des-event-router:latest

   sudo podman image tag localhost/des-tool:latest repository/des-tool:latest

   sudo podman image tag localhost/confluentinc/cp-kafka:latest repository/confluentinc/cp-kafka:latest

   sudo podman image tag localhost/confluentinc/cp-schema-registry:latest repository/confluentinc/cp-schema-registry:latest

   sudo podman image tag localhost/confluentinc/cp-zookeeper:latest repository/confluentinc/cp-zookeeper:latest

3. Execute the commands to delete the old images from the local system.

   podman rmi [repository]/[image name]:[TAG]

   Sample commands:

   sudo podman rmi localhost/des-event-processor:latest

   sudo podman rmi localhost/des-config-installer:latest

   sudo podman rmi localhost/des-event-cleanup:latest

   sudo podman rmi localhost/des-event-pull-adapter:latest

   sudo podman rmi localhost/des-event-router:latest

   sudo podman rmi localhost/des-grafana:latest

   sudo podman rmi localhost/des-tool:latest

   sudo podman rmi localhost/confluentinc/cp-kafka:latest

   sudo podman rmi localhost/confluentinc/cp-schema-registry:latest

   sudo podman rmi localhost/confluentinc/cp-zookeeper:latest

4. Connect to the podman machine through ssh and run the commands to push the DES images.

   podman image push [repository]/[image name]:[TAG]

   NOTE: Repository, image name, and TAG should be the version of the DES pack (for example, 21.0.6).

   Sample commands:

   sudo podman image push repository/des-event-processor:latest --tls-verify=false

   sudo podman image push repository/des-config-installer:latest --tls-verify=false

   sudo podman image push repository/des-event-cleanup:latest --tls-verify=false

   sudo podman image push repository/des-event-pull-adapter:latest --tls-verify=false

   sudo podman image push repository/des-event-router:latest --tls-verify=false

   sudo podman image push repository/des-grafana:latest --tls-verify=false

   sudo podman image push repository/des-prometheus:latest --tls-verify=false

   sudo podman image push repository/des-demo-webapp-kafka:latest --tls-verify=false

   sudo podman image push repository/des-tool:latest --tls-verify=false

   sudo podman image push repository/confluentinc/cp-kafka:latest --tls-verify=false

   sudo podman image push repository/confluentinc/cp-schema-registry:latest --tls-verify=false

   sudo podman image push repository/confluentinc/cp-zookeeper:latest --tls-verify=false

5. Prepare the helm charts for deployment by downloading the DES chart from the distribution pack provided (des-docker\src\helm\kafka\)

   

6. Configure the DES chart by changing the fields in /helm/des/values.yaml according to the images.
7. Set the registry as shown in the below screen shot.

   

8. Configure the blank fields in the file as shown below.
   • schema_ip
   • kafka_ip
   • t24_host_ip
   • stream_host_ip

     

9. Set the DB properties as shown in the below screen shot.

   

10. In the values.yaml file, uncomment the rows as shown in the below screen shot.

    

11. In the des-config.yaml file, uncomment the rows as shown in the below screen shot.

    

12. In the des-pull-adapter.yaml file, uncomment the rows as shown in the below screen shot.
