Kubernetes Deployment

Manual Deployment

To manually deploy the application to a Kubernetes cluster, follow these steps:

2. Deploy the application using Helm: helm upgrade --install interview-task -n <namespace> -f interview_task/values.yaml ./interview_task

Environment Variables

Configure the following environment variables for both local development and Kubernetes deployments:

Variable	Description	Example
PORT	Port for the webserver (as a string)	":3000"
DATABASE_NAME	Name of the database	"my_database"
DATABASE_USER	Username for the database	"db_user"
DATABASE_PASSWORD	Password for the database user	"password123"
DATABASE_ADDRESS	Address for the database connection	"tcp(127.0.0.1:3306)"

Notes:

• Ensure that the secret.yaml file contains the appropriate database credentials and other sensitive information before deploying to Kubernetes.
• Modify the <namespace> placeholder with the actual namespace where you want to deploy the application.
