Configuring Helm Charts

Configuring Services

Copy the drive.json and runtime_environment.json files, which are extracted, available inside the drive/etc folder to the helm chart folder, and update the config paramaters before deploying the helm charts

In the drive.json file, update the ip address value with 127.0.0.1 (replace <VM IP address>) as shown below.

"kafkaServer": {
                        "ip": "<VM IP address>",
                        "port": 9092
                    },
                    "zooKeeperServer": {
                        "ip": "<VM IP address>",
                        …
		   "name": "bootstrapServers",
                        "stringListValue": {
                            "values": [
                                "<VM IP address>:9092"
                            ]
                        }
		    {
                    "name": "databaseServerIp",
                    "stringValue": "<VM IP address>"
                  },

In the tomcat configuration section, update the host name as shown below:

"tomcatConfiguration": {
            "hostname": "acme-tomcat",
            "httpConfiguration": {
                "httpBoundOnlyToLocalhost": false
            },
            "httpsEnabled": false,
            "port": 8081,
            "shutdownPort": 8010,
            "usingSelfSignedCertificate": false
}

Also, update the runningMode as ScaledDistributed.

"runningMode": "ScaledDistributed",
"solution": {           
…

In the interface_application.env file, update the VM IP Address.

export DRIVE_DB_IP_ADDRESS="<VM IP address>"
export NAMESERVICE_SERVER_IP="<VM IP address>"
export EXTERNAL_KAFKA_BROKERS="<VM IP address>:9092"…

Similarly for the runtime_environment.json file, update the network values as shown below:

"network": {
        "interface": "eth0",
        "ipV6Available": false,
        "usingIpV4": true
    },

Tagging Docker Images

Contact with the HCL support team to get the images for tomcat (HCL_Detect_x.x.x_Docker_Tomcat_Image.zip) and feed (HCL_Detect_x.x.x_Docker_Feed_Image.zip). Unzip both the images, and tag the images with required name. After tagging the images, update the image references in the values.yaml. For more information of tagging docker images, refer https://docs.docker.com/reference/cli/docker/image/tag/.

docker load –input HCL_Detect_Feed_12.1.8_Docker.tar
docker tag <imageid> <gcr repo tag>
docker push <gcr repo tag>

After performing the loading and tagging of docker images, in the values.yaml file, update the volumeName with the pvc name like shown below.

pvc:
  volumeName: ced-pvc

In the values.yaml file of helm charts, update the timezonevalue wrt. the timezone of the VM, where services like fastpast, pinpoint, nameserver, are deployed. For example, update the "timezonevalue:" as "EST5EDT" to set the US Eastern Timezone.

Deploying Detect Services

Using the below Helm command, install the Detect services on the OpenShift cluster.

helm install detect .

As a result, the output will be as shown below.
