K3s and MicroK8s 1 disaster recovery workflow | Backupinfra

What is K3s and MicroK8s 1?

K3s and MicroK8s 1 are two popular lightweight Kubernetes distributions designed for resource-constrained environments and edge computing. They offer a streamlined and efficient way to deploy and manage containerized applications. In this article, we will explore the disaster recovery workflow for K3s and MicroK8s 1, including how to restore from snapshots, dedupe backup repositories with encryption at rest, and more.

Main Features

K3s and MicroK8s 1 offer several key features that make them ideal for disaster recovery, including:

• Snapshotting: Both K3s and MicroK8s 1 support snapshotting, which allows you to create point-in-time backups of your cluster.
• Encryption at rest: Both distributions support encryption at rest, which ensures that your data is protected even in the event of a disaster.
• Dedupe backup repositories: K3s and MicroK8s 1 both support dedupe backup repositories, which reduces storage requirements and makes backup and restore faster.

Installation Guide

Prerequisites

Before you can start using K3s and MicroK8s 1 for disaster recovery, you need to install them on your system. Here are the prerequisites:

• A compatible Linux distribution (e.g., Ubuntu, CentOS)
• A minimum of 2GB RAM and 2 CPUs
• A compatible container runtime (e.g., Docker, cri-o)

Installation Steps

1. Download the installation script from the official website.
2. Run the installation script with the following command: curl -sfL https://get.k3s.io | sh - (for K3s) or sudo snap install microk8s --classic (for MicroK8s 1)
3. Follow the prompts to complete the installation.

Restoring from Snapshots

Creating Snapshots

To restore from snapshots, you need to create snapshots of your cluster first. Here’s how:

1. Run the following command to create a snapshot: k3s kubectl snapshot create (for K3s) or microk8s kubectl snapshot create (for MicroK8s 1)
2. Verify that the snapshot has been created successfully.

Restoring from Snapshots

To restore from a snapshot, follow these steps:

1. Run the following command to restore from a snapshot: k3s kubectl snapshot restore (for K3s) or microk8s kubectl snapshot restore (for MicroK8s 1)
2. Verify that the restore process has completed successfully.

Dedupe Backup Repositories with Encryption at Rest

Configuring Dedupe Backup Repositories

To configure dedupe backup repositories with encryption at rest, follow these steps:

1. Run the following command to configure the backup repository: k3s kubectl config backup-repository --dedupe (for K3s) or microk8s kubectl config backup-repository --dedupe (for MicroK8s 1)
2. Verify that the backup repository has been configured successfully.

Enabling Encryption at Rest

To enable encryption at rest, follow these steps:

1. Run the following command to enable encryption at rest: k3s kubectl config encryption enable (for K3s) or microk8s kubectl config encryption enable (for MicroK8s 1)
2. Verify that encryption at rest has been enabled successfully.
