How do I achieve a NodePort scenario in my machine-Kubernetes?

I want to test 2 things:
If pod-pod communication works? (Yes)
If external user can communicate with pods?(Yes) But how? (Using nodeport)

How do I achieve this?

Hello,

Achieving a NodePort scenario in Kubernetes can be done by following these steps:

1. Create a service for your pod: First, you need to create a service for your pod using the "NodePort" type. This can be done by including the "type: NodePort" field in your service definition.

2. Specify the NodePort: In the service definition, you can also specify the NodePort that you want to use for external access. This port must be within the range of 30000-32767.

3. Allow traffic through the firewall: If you are using a firewall on your machine, you will need to allow traffic on the NodePort that you specified in the previous step.

4. Accessing the service: Once the service is created, you can access it externally by using the IP address of your node and the NodePort that you specified. For example, if your node's IP address is 192.168.1.100 and your NodePort is 30000, you can access the service at 192.168.1.100:30000.

With this setup, you can test pod-pod communication by accessing the service from within your cluster. You can also test external user communication by accessing the service from outside the cluster using the NodePort.

I hope this helps! Let me know if you have any further questions.
