Autoscale and ConfigMap, secret

Introduction

Went through Kubernetes concepts and operations, including scaling deployments, autoscaling based on CPU usage, working with ConfigMaps, creating secrets, and managing volumes and PersistentVolumeClaims (PVCs).

Prerequisite

• A working Kubernetes cluster.
• kubectl command-line tool configured to communicate with cluster.

Use Case

Understanding and mastering these Kubernetes concepts and operations is vital for successfully configuring and managing applications within a Kubernetes environment.

Research

• Using Local Path Provisioner: Learn how to set up local path provisioning for storage in Kubernetes.
• Configure a Pod to Use a PersistentVolume for Storage: Dive into configuring pods to use PersistentVolumes for storage needs.

Try It Yourself

By actively practicing, you'll gain hands-on experience and a deeper understanding of these essential Kubernetes concepts.

1. Scaling Deployments: Use the kubectl scale command to scale a deployment, adjusting the number of pod replicas as needed.

2. Autoscaling Based on CPU Usage: Implement autoscaling for a deployment, ensuring it dynamically adjusts the number of replicas based on CPU utilization.

3. Working with ConfigMaps: Create a ConfigMap, add it to your deployment, and observe how environment variables from the ConfigMap become available within the pod.

4. Creating Secrets: Create a secret, retrieve its values, and decode them as necessary to securely manage sensitive information within your Kubernetes applications.

5. Managing Volumes and PVCs: Create PersistentVolumes and matching PersistentVolumeClaims, and configure them in your application pods to efficiently manage storage.
