Deployment Procedure
Review the Prerequisites before you start the deployment. The steps to deploy the web application services are:
Update db-stack.yml File
By default, the Kafka database service is configured to be used within the Docker network. To allow connections on the private IP of the instance, update the db-stack.yml file to set the Kafka advertised listener on the database server so that the web application server can access Kafka.
To update the db-stack.yml file, do the following:
- Run the following command on the database server to open the - db-stack.ymlfile in edit mode:- vi /apps/cyware/conf/db-stack.yml 
- Delete the following line: - - KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://broker1:29092,PLAINTEXT_HOST://broker1:9092 
- Uncomment the following lines: - - KAFKA_ADVERTISED_LISTENERS=PLAINTEXT://broker1:29092,EXTERNAL_HOST://<PRIVATE IP of machine>:9092 - KAFKA_LISTENER_SECURITY_PROTOCOL_MAP=PLAINTEXT:PLAINTEXT,EXTERNAL_HOST:PLAINTEXT 
- In - KAFKA_ADVERTISED_LISTENERS, replace- <PRIVATE IP of machine>with the private IP address of the database server for the- EXTERNAL_HOSTvalue.
- Save and exit. 
After updating the db-stack.yml file, run the following commands to restart the database stack and apply the updates:
cd /apps/cyware/conf docker stack deploy -c db-stack.yml db
Update vars.yml File
The vars.yml file includes variables, such as base path, database passwords, and endpoints, that are needed for the Intel Exchange application and database services.
Before you Start
Ensure that you have configured static IP addresses for the database and web application servers.
Steps
To update the vars.yml file, do the following:
- Run the following command on the web application server to open the - vars.ymlfile in edit mode:- vi /home/centos/ctix-installer/vars/ctix/vars.yml 
- Update the respective values, such as base and log paths, database URLs and passwords, and more. 
- Save and exit. 
Deploy Intel Exchange Application Stack
To deploy the web application services, go to the /home/centos/ directory and run the following command on the web application server:
bash app.sh
Note
The app.sh script takes some time to run. Do not interrupt while the script is running.
