In the application project folder, open the build properties file (e.g. buildDemo.properties) and enable docker build as follows:
Code Block
language text
BUILD_DOCKER_IMAGE = Y
Perform this step if you are using Oracle database only. In the build properties file (e.g. buildDemo.properties), uncomment the following property:
Code Block
language text
DB = oracle

Open the ../\Docker_Dependencies/\Dockerfile file and update as follows:

Ensure to change the contents of Dockerfile according to your application name and work folder in the indicated places:
