• AWS_REGION: ap-south-1

Changes to be made in the Repository

• Navigate to kubernetes-1.27 branch
• Enable GitHub Actions
• Open the GitHub Actions workflow file.
• Specify the branch name you wish to enable GitHub Actions for.
• Configure Infrastructure-as-Code
• Navigate to infra-as-code/terraform/sample-aws.
• Open input.yaml and enter details such as domain_name, cluster_name, bucket_name, and db_name.
• Configure Application Secrets
• Navigate to config-as-code/environments.
• Open egov-demo-secrets.yaml.
• Enter db_password and ssh_private_key. Add the public_key to your GitHub account.
• Generate SSH Key Pair
• Choose one of the following methods to generate an SSH key pair: Method a: Use an online website (Note: This is not recommended for production setups, only for demo purposes): https://8gwifi.org/sshfunctions.jsp Method b: Use OpenSSL commands: openssl genpkey -algorithm RSA -out private_key.pem openssl rsa -pubout -in private_key.pem -out public_key.pem

Finalize Installation

• After entering all the details, push these changes to the remote GitHub repository. Open the Actions tab in your GitHub account to view the workflow. You should see that the workflow has started, and the pipelines are completing successfully.

Create Superuser

• Connect to the kubernetes cluster, from your local machine using (aws eks update-kubeconfig --region ap-south-1 --name $CLUSTER_NAME) and run below command
• kubectl port-forward svc/egov-user -n egov 8080:8080

And in another window, run the below curl:

curl --location 'http://localhost:8080/user/users/_createnovalidate'
--header 'Content-Type: application/json'
--data-raw '{ "requestInfo": { "apiId": "Rainmaker", "ver": ".01", "ts": null, "action": "_update", "did": "1", "key": "", "msgId": "20170310130900|en_IN", "authToken": "51e00caf-3218-4f15-ba70-a45f7d40abc1" }, "user": { "userName": "<>", "name": "Admin User", "gender": null, "mobileNumber": "9898989898", "type": "EMPLOYEE", "active": true, "password": "<>", "roles": [ { "name": "Super User", "code": "SUPERUSER", "tenantId": "mz" } ], "emailId": "[email protected]", "tenantId": "mz" } }'

Cleanup and Uninstallation of DIGIT Infrastructure

As you wrap up your work with DIGIT, ensuring a smooth and error-free cleanup of the resources is crucial. Regular monitoring of the GitHub Actions workflow's output is essential during the destruction process. Watch out for any error messages or signs of issues. A successful job completion will be confirmed by a success message in the GitHub Actions window, indicating that the infrastructure has been effectively destroyed. When you're ready to remove DIGIT and clean up the resources it created, proceed with executing the terraform_infra_destruction job. This action is designed to dismantle all setup resources, clearing the environment neatly. We hope your experience with DIGIT was positive and that this guide makes the uninstallation process straightforward.

How to Run the Terraform Infrastructure Destruction Job

• To initiate the destruction of a Terraform-managed infrastructure, follow these steps:
• Navigate to Actions.
• Click DIGIT-Install workflow.
• Select Run workflow.
• When prompted, type "destroy". This action starts the terraform_infra_destruction job.
• You can observe the progress of the destruction job in the actions window.
