Manifests

This repository contains Kubernetes configurations for deployment of all Sympoll's apps and infrastructure. These configurations are tailored for deployment in Minikube.

Prerequisites

• Minikube installed
• Kubectl installed
• Helm (optional, for managing Ingress controllers)

Getting Started

Start Minikube

1. Start Minikube with the desired Kubernetes version:

   minikube start --kubernetes-version=v1.26.0

2. Enable the Ingress addon:

   minikube addons enable ingress

3. Start the Minikube tunnel to expose the Ingress service:

   minikube tunnel

   Leave this terminal open while using Ingress, as it needs to keep running to maintain the tunnel.

Deploy the Application

1. Apply the Kubernetes configurations:

   kubectl apply -f frontend-and-poll-managment/

2. Verify that all pods are running:

   kubectl get pods

3. Check the status of the services:

   kubectl get services

4. Ensure the Ingress resource is created:

   kubectl get ingress

Accessing the Application

1. To access the frontend, you can use Minikube’s IP and the service port:

   minikube service frontend --url

2. Alternatively, if using Ingress, open a browser and navigate to http://localhost to see the frontend.

Useful Commands

• Get Minikube IP:

  minikube ip

• Check logs of a specific pod:

  kubectl logs <pod-name>

• Execute a command inside a container:

  kubectl exec -it <pod-name> -- /bin/sh

• Delete all resources:

  kubectl delete -f frontend-and-poll-managment/

• Update the deployment:

  kubectl rollout restart deployment <deployment-name>

• View detailed events for debugging:

  kubectl get events

Notes

• Ensure your ConfigMap for initializing PostgreSQL is correctly referenced in your PostgreSQL deployment.
• Verify that your Ingress controller is correctly routing traffic to the services.

Troubleshooting

• Pods not starting: Check the logs using kubectl logs <pod-name> and kubectl describe pod <pod-name> for more details.
• Service not accessible: Ensure that the service is correctly configured and that the Ingress controller is properly set up.

Feel free to adjust configurations according to your needs.
