SIM-FE-URL:port change in .env is not reflected without rebuilding Docker image

[YeagerAI-Bulat]

Describe the bug

When changing the frontend URL:port in the .env file of the genlayer-simulator repository and restarting all Docker containers, the URL:port change is not applied. The configuration seems to be baked into the Docker image at build time. Deleting the frontend image and rebuilding it reflects the new URL:port, but this is not an efficient workflow.

To Reproduce

• Clone the genlayer-simulator repository.
• Build and start the Docker containers using docker compose up -d.
• Change the VITE_WS_SERVER_URL or VITE_JSON_RPC_SERVER_URL values in the .env file.
• Restart the containers using docker compose down && docker compose up -d command.
• Access the frontend application and notice that it's still running on the old URL/port.

Expected behavior

Changing the VITE_WS_SERVER_URL or VITE_JSON_RPC_SERVER_URL values in the .env file and restarting the containers should update the frontend to run on the new URL:port without needing to rebuild the Docker image. JSON-RPC container supports this without any issues.

Actual behavior

The frontend continues to run on the old URL:port unless the Docker image is deleted and rebuilt.

Suggested Solution

Implement dynamic configuration for the frontend URL:port so that it reads the VITE_WS_SERVER_URL or VITE_JSON_RPC_SERVER_URL values from the .env file at runtime instead of build time. This could involve:

• Adjusting the frontend application's startup script to read the URL:port configuration when the container starts.

Additional context

This enhancement would streamline development and deployment processes by eliminating the need to rebuild the Docker image for port changes.
