the basic syntax of deployment.YAML and Kubernetes structure

Question

Accepted Answer

Deployment.yaml is used to define Kubernetes deployments and their properties.

Deployment.yaml is a Kubernetes manifest file that defines the desired state of a deployment.
It includes properties such as the number of replicas, the container image to use, and the ports to expose.
The structure of a deployment.yaml file includes metadata, spec, and status sections.
The metadata section includes information such as the name and labels of the deployment.
The spec section includes the desired state of the deployment, including the number of replicas and the container image to use.
The status section includes information about the current state of the deployment.
Kubernetes structure includes nodes, pods, services, and deployments.
Nodes are the physical or virtual machines that run Kubernetes.
Pods are the smallest deployable units in Kubernetes and can contain one or more containers.
Services provide a way to expose pods to the network.
Deployments manage the deployment and scaling of pods.
Kubernetes uses a declarative approach to configuration management, meaning that the desired state is defined in configuration files like deployment.yaml.
