-----END RSA PRIVATE KEY-----
Generate SSH key pairs (Use either method (a) or method (b)) to update the private key.
a. Using the online website (not recommended for production setup. To be only used for demo setups): https://8gwifi.org/sshfunctions.jsp
b. Using OpenSSL :
openssl genpkey -algorithm RSA -out private_key.pem openssl rsa -pubout -in private_key.pem -out public_key.pem
Add the public key to your GitHub account (reference: https://www.youtube.com/watch?v=9C7_jBn9XJ0&ab_channel=AOSNote )
Change to the deployer directory
cd ../..
cd deploy-as-code/deployer
go run standalone_installer.go
Run the below command to deploy nginx-ingress
kubectl apply -f ../../config-as-code/helm/charts/backbone-services/azure-nginx/ingress.yaml
Check the pods once all services are deployed successfully
Run the below command to get the load balancer id
kubectl get svc -A | grep ingress
Copy the load balancer id and add it to your domain provider against your domain name.
