Read the first 6 YAML Configuration flashcards as text

  1. What format are Kubernetes manifest files typically written in?

    Answer: YAML

    Kubernetes uses YAML (YAML Ain't Markup Language) for manifest files that define resources like Pods, Services, and Deployments.

  2. What are the four required fields in a Kubernetes manifest?

    Answer: apiVersion, kind, metadata, spec

    Every Kubernetes manifest requires apiVersion (API group), kind (resource type), metadata (name and labels), and spec (desired state).

  3. What does 'kubectl apply -f' do?

    Answer: Creates or updates resources defined in a file

    kubectl apply -f applies the configuration from a YAML file, creating the resource if it doesn't exist or updating it if it does.

  4. What is a Kubernetes label?

    Answer: A key-value pair attached to resources for identification and selection

    Labels are key-value pairs attached to Kubernetes objects that can be used to organize, select, and filter resources.

  5. What is a Kubernetes namespace?

    Answer: A virtual cluster partition for organizing resources

    Namespaces provide virtual cluster partitioning, allowing teams or projects to share a cluster while isolating their resources.

  6. What is the purpose of resource limits in a Pod spec?

    Answer: To cap the maximum CPU and memory a container can use

    Resource limits define the maximum amount of CPU and memory a container can consume, preventing any single container from monopolizing cluster resources.
