Quick Setup (AWS)

Installation guide for quick deployment of DIGIT via GitHub Actions in AWS. (This setup is strictly for setting up dev and test environments)

Known Issues:

  1. ap-south-1 is hardcoded in terraform script. It will be moved to input.yaml shortly.

  2. Secrets should be encrypted using SOPS. Currently private repo will be required to restrict access to sensitive information


This guide provides step-by-step instructions for installing DIGIT using GitHub Actions within an AWS environment.


  • AWS account with adminstrative privilege

  • Github account


Create IAM User and generate Access Key & Secret Key

  • Skip this step if you already have access and secret key

  1. Create an IAM User with adminstrative privilege in yout AWS account

  2. Generate ACCESS_KEY and SECRET_KEY for the IAM user.

// Access Keys will look something like below


Configure GitHub Repository

  1. Fork the DIGIT-DevOps Repository into your account on GitHub (Uncheck Copy the master branch only while forking) see the below image where to find fork in Github.

  1. Enable github workflow by clicking on I understand my workflow, go ahead and enable them

  1. Navigate to the repository settings, under the security section go to Secrets and Variables, click on actions and add the following repository secrets one by one by clicking on New repository secret:

The following secrets needs to be added:










Once all four secrets are added it will look like below:

  • Clone the forked DIGIT-DevOps repository (using git clone command) and open the repo in the code editor or optionally you can use github web editor by replacting github.com with github.dev.

  • Switch the branch from master to DIGIT-2.9LTS using the below command.

git checkout DIGIT-2.9LTS

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

Store the generated private key and public key in separate files on your local.

The private key will look like:

-----BEGIN RSA PRIVATE KEY----- MIIEpAIBAAKCAQEAue4+1*********************K7mGXRIv6enEP4lN/y9i287wsNBpg+IDGjIV************************************************************************************ +zrt79wBgG5vlGMoT1hysRDpxNNlDdimE6G8OHaCj6e5cwhXrMt1swKFUwVsZaFx UMv1xVFU/OsrJ8v8***************************************************************** **********************Sd74a4d2h28pIEHNbrlvAVn7Zt9IDC kgske+VBY+X0D2en1l8bt3Vdnn5xgcDQsPmp6GdoRfE2luJ6lAe+mdkCgYEA0wUj tUHRH9sI3X86wZVREt*************************************************************** **********************************poTy6hNQr9IT2TsBckuN/qqockBR/j+iRap7lec3tJM vdmMVP0Ed7GjBiSBVeHeHVg+Dt6+AqayWqU0hPkCgYB6o+bof7XnnsmBjvLVFO15 LlDiIZQFBtr7CriRDD2Nx************************************************************* ************************************TCaHk8CGmA+TXSKM9q7cTtMb6ythUQhZrpq 0EEY5TgQKBgQ*************************************************************8/PD+mT 5jFvon5Q== -----END RSA PRIVATE KEY-----

And the public key will look like:

Configure Infrastructure Parameters:

  1. In your editor go to DIGIT-DevOps/infra-as-code/terraform/sample-aws.

  2. Open input.yaml and enter details such as domain_name, cluster_name, bucket_name, db_name and add public_ssh_key generated in the above step. (Fill in the inputs as per the regex mentioned in the comments.) Following variables needs to be set in input.yaml



Name of the EKS cluster. The Cluster name can have only lowercase alphanumeric characters and hyphens


The name of the ssh key. Can contain any alphanumeric character


The public ssh key generated in section above (Generate SSH Key Pair)


Name of the database. The name that you enter should contain only alphanumeric characters


Username of the root user. DB user name must contain only alphanumeric characters


The domain url for the UI


Name to be given to S3 bucket which will be created in terraform. This bucket will store the terraform state.

Configure Application Secrets

  1. Go to deploy-as-code/charts/environments.

  2. Open env-secrets.yaml.

  3. Enter db_password and ssh_private_key (in git-sync section). (please make sure that the indentation is same as the sample value given for ssh_private_key)

  4. Add the public key to your GitHub account.

Trigger Installation

After entering all the details, push these changes to the remote GitHub repository (in the same DIGIT-2.9LTS branch). Open the Actions tab in your GitHub account to view the workflow. You should see that the workflow has started, and the pipelines are completed successfully.

This indicates that your setup is correctly configured, and your application is ready to be deployed. Monitor the output of the workflow for any errors or success messages to ensure everything is functioning as expected.

KubeConfig Setup

For guidance on setting up your AWS CLI, please follow the instructions provided in Installation Guide - Production Setup on AWS. Additionally, ensure your AWS CLI is correctly configured by referring to the official AWS documentation on Configuring the AWS CLI - AWS Command Line Interface. Confirm your AWS credentials are correctly set by executing:

If not create the profile using:

aws configure --profile <profile_name>

Run the below command to export AWS Credentials

export AWS_PROFILE=<profile_name>

Proceed only after verifying the correct configuration of your credentials. For any uncertainties on how to set up the credentials, consult the AWS documentation for detailed instructions. To check if credentials are properly set run the command:

aws configure list --profile <profile_name>

Run the following command to get kubernetes configuration:

# Run the below command and give the respective region-code and the cluster name
aws eks --region <aws-region> update-kubeconfig --name <cluster_name>

Verify that you can connect to the cluster by running the following command.

kubectl config use-context <cluster_name>

kubectl get nodes 

kubectl get pods -A

Once the deployment is done get the CNAME of the nginx-ingress-controller:

kubectl get svc ingress-nginx-controller -n backbone -o jsonpath='{.status.loadBalancer.ingress[0].hostname}'

The output of this will be the something like this:


Add the CNAME to your domain provider against your domain name.

Post Deployment

Login to the employee dashboard with the username and password provided in env-secrets.yaml file using the domain name provided in input.yaml.

Cleanup & 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:

  1. Navigate to Actions.

  2. Click DIGIT-Install workflow.

  3. Select Run workflow.

  4. 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.

Note: For DIGIT configurations created using the master branch.

If DIGIT is installed from a branch other than the main one, ensure that the branch name is correctly specified in the workflow file. For instance, if the installation is done from the digit-install branch, the following snippet should be updated to reflect that.

name: DIGIT-Install workflow
# Workflow branch creating cluster against the input.yaml file  
      - master
      - digit-install
        description: 'Type "destroy" to run the terraform_infra_destruction job.'
        required: true
        default: ''
