This is a simple Node.js application using the Express framework, Docker and Kubernetes. It provides basic health-check routes and retrieves system information such as IP addresses and hostname.

• Health check endpoint to verify the status of the application.
• System information endpoint that returns the namespace, hostname, IP address, and a timestamp.
• Logging with morgan to monitor HTTP requests.
• Uses os module to retrieve network interface details.

• Node.js (v12.x or higher)
• npm (v6.x or higher)

1. Clone this repository.

   git clone <repository_url>

2. Navigate to the project directory.

   cd <project_directory>

3. Install the dependencies.

   npm install

The application can use the following environment variables:

• PORT: Port on which the server will listen (default is 9500).
• MY_POD_NAMESPACE: The namespace for the pod (defaults to docker).
• MY_POD_NAME: The hostname of the pod (defaults to system hostname).
• MY_POD_IP: The IP address of the pod (defaults to the machine's network interface addresses).

1. To start the server, run the following command:

   node index.js

2. The application will be running on the port specified by the PORT environment variable (or 9500 by default).

This endpoint returns the health status of the server.

Response:

{
  "status": "ok",
  "message": "we are up and running 😘"
}

This endpoint returns system information such as the namespace, hostname, IP addresses, and a timestamp.

Response:

{
  "status": "ok",
  "namespace": "docker",
  "hostname": "<hostname>",
  "ip": [
    { "eth0": "192.168.1.100" }
  ],
  "timestamp": 1684567890123
}

The server uses the morgan library for request logging. Logs are printed in the console in the "dev" format.
