Solution Pods optional

Summary: This article provides a hands-on lab for understanding Kubernetes pods, including creation, inspection, and configuration using YAML.

Key Notes

In this lesson, you’ll explore a hands-on lab that deepens your understanding of Kubernetes pods. We’ll start by checking existing pods, create new ones with various images, inspect pod details, and adjust a pod configuration using YAML.
1. Verify Existing Pods
First, examine the current pods running in your Kubernetes cluster by executing:
You might see an output similar to this:
This command checks pods in the default namespace. In future lessons, we’ll dive deeper into namespaces and how they manage resources.
1. Creating a Pod with the Nginx Image
To create a new pod using the Nginx image, use the following command:
—image=nginx
The pod creation is confirmed in the output:
pod/nginx
After creating the pod, run the command again to see all current pods:
You might see a list similar to this:
0/1
Here, several pods have been created and will be examined further.
1. Inspecting Pod Details
This command outputs extensive information such as start time, node assignment, labels, and container details. In the section under “Containers,” you should see an entry like:
Containers:
busybox:
Container ID: containerd://b05cd692af1f3b433883f9a8ece19ec2e8c4fcf861aa97ae6a82857ed6037a6d
Image: busybox
Determine Node Placement
To see which nodes are hosting your pods, run:
Sample output:
