Note:<\/strong> Pod YAML <\/strong>also Deployment, Service, ReplicaSet, and others follow the below four top-level fields, these are the top-level or root-level properties.<\/p>\n\n\n\n

apiVersion:
kind:
metadata:

spec: <\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

apiVersion:<\/strong> this version depends on what we are trying to create we must use the right API version. Such as POD for version will be v1<\/strong>, service<\/strong> for version will be v1<\/strong>, ReplicaSet<\/strong> for version will be apps\/v1<\/strong>, and Deploymen<\/strong>t for apps\/v1<\/strong><\/p>\n\n\n\n

Kind: <\/strong>This refers to the type of object we are trying to create which in this case happens, such as kind can be a Pod, Deployment, Service, or ReplicaSet. <\/p>\n\n\n\n

Metadata:<\/strong> The metadata is data about the object like its name, labels, etc. Under the metadata, everything is intended to the right a little bit and so under the things are children of metadata. <\/p>\n\n\n\n

Spec:<\/strong> This describes the desired state of the pod <\/p>\n\n\n\n
