Manifests

Updated Apr 07, 2022 ·

Overview​

A Manifest defines the properties and configurations of Kubernetes resources. It uses the spec (specification) to describe resource-specific attributes.

How Manifests Work​

  1. Use <code>kubectl create</code> to create resources from the manifest.
  2. kubectl sends the manifest to the Kubernetes API server.
  3. The API server performs the following actions:
    • Selects a node with available resources
    • Schedules the Pod on the selected node
    • The node pulls the Pod's container image
    • The node starts the Pod's containers

Sample Manifest​

Here’s an example manifest for creating a basic NGINX Pod:

apiVersion: v1 
kind: Pod
metadata:
    name: pod-nginx
spec:
    containers:
    - name: container-nginx-1
      image: nginx:latest

Key Manifest Properties:

  • apiVersion: The API version (usually v1).
  • kind: The resource type being created (e.g., Pod).
  • metadata: Information about the resource.
  • spec: Configuration details for the resource.
