00:00 - What is a Kubernetes Service and When Do We Need It?
What is a Kubernetes service and when do we need it? What are the different kinds of Kubernetes services components that we have? We will discuss and I will try to give a general overview of the services. We will have a short demo, as well.
Starting from the pod, as we know that the pod is the basic component, the basic unit of Kubernetes. The pod has its own IP address. But the issue with the pod is that whenever it’s failed or is destroyed, it gets a new IP. It’s very difficult for the client or for the team to manage the new IPs. In this regard, Kubernetes provides us with a solution with the services. What advantage the services component gives us is that it provides a stable IP, and load balancing capacity. The client does not need to remember the IP addresses of the pods. In the case that it wants to use the services, it just needs to remember one single IP.
