Steps To Start

Localhost

1. Open the project on Ecllipse/ VS Code
2. Launch Eureka Discovery Server
3. Launch Database Server
4. Launch Gateway Server
5. Launch All other Services

Docker

1. Go to root of the project
2. Run Docker-compose up to Run the server
3. Run the Client Separately
4. Make sure Client Project running normally or in docker has correct server URL

Kubernetes (Local)

1. Go to k8s Directory
2. Run kubectl apply -f .
3. Check the Zuul service port number
4. Update Application URL by setting it as zuul nodeport url
5. Run client Code

Kubernetes Google Gloud

1. Install Google Cloud SDK on PC
2. Launch Docker Desktop on PC (Make sure Kubernetes is on)
3. Create a new Cluster with 4 CPU and 8GB
4. Set Kubernetes Context to Google Cloud Cluster
5. Go to K8s Directory
6. Run kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v0.40.2/deploy/static/provider/cloud/deploy.yaml

7. Code Deployment

8. Go to Kubernetes Depoyment Code directory
9. Run kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v0.40.2/deploy/static/provider/cloud/deploy.yaml
10. Run kubernetes apply -f .
11. Check Google Cloud Console -> Services
    1. Look for a load balancer service
    2. Copy the Extenal Load Balancer URL
    3. Run it in Browser
    4. Wait for Sometime for services to start (15 min atleast)
12. Go to services -> Create Ingress (This step requires a NodePort service - Take a note if modifying K8s)
    1. Create Ingress
    2. Specify Path as default
    3. Specify Service as zuul-srv
    4. Create
13. Run the Client with External Load balancer IP

TODO - CORS Observations (Need Help)

• Auth Service

1. Route must hvae Cross origin annotation independent of everything lese it will surely give erro
2. Registreation routes will still give error with origins annotation(Needs cors().and() in Security fofx to fix it)

• Client

1. Cors Interceptor with allow origin header breaks CORS

• Zuul

1. cors().and() breaks JWT Code (Prevents any Request from even hitting JWT filter or auth entry point)
2. CORS filter Bean causes Error for Cross-Origin header missing
3. adding res.addHeader("Authntication") in JWT Filter fixes code temporailiy in Chrome Only

• Zuul Properties

1. SensitiveHeaders must be set blank (Cant be removed)
2. Ignored Header causes Origin Error

Update [Fixed]

• To Run Client and server in localhost, use extension moesif cors chrome extension
• To Deploy in a remote device append https://cors-anywhere.herokuapp.com/ before http://
• Make sure localhost client has port number in gateway url i.e localhost:9000
