Introduction

Docker images package applications and their dependencies into a portable format. For example, you can save a Docker image as a file for backup, storage, or transfer between different environments.

Docker provides the docker save command to create a TAR archive from a Docker image. As a result, you can store the TAR file for future use.

In this guide, we will explain how to save a Docker image as a TAR file and verify the generated archive.

Prerequisites

Before you begin, make sure you have the following:

- Docker is installed on the server.

- The Docker service is running.

- You have the required permissions to run Docker commands.

- The Docker image that you want to save is available on the server.

- Make sure you have enough disk space to create the TAR file.

Introduction

SSL/TLS is used to secure communication between a website and its visitors. When SSL/TLS is configured, the website can be accessed using HTTPS instead of HTTP.

On a Linux server, SSL/TLS configuration generally involves installing the required SSL certificate, configuring the web server, redirecting HTTP traffic to HTTPS, and verifying the certificate and TLS connection.

This guide explains some commonly used Linux commands to check SSL certificates, test HTTPS connectivity, and verify the web server configuration.

Prerequisites

Before working with SSL/TLS on a Linux server, make sure you have:

- Root or sudo access to the server.

- SSH access to the Linux server.

- A working website and domain name.

- Apache or Nginx installed.

- An SSL/TLS certificate and private key.

- Basic knowledge of Linux commands.

Implementation

Step 1: Check the Web Server

First, identify whether Apache or Nginx is running on the server.

Introduction

A well-designed backup strategy is a fundamental component of business continuity, data protection, and disaster recovery for AWS workloads.

Simply creating backups does not guarantee that an organization can recover successfully from data loss, infrastructure failure, accidental deletion, security incidents, or regional disruptions. An effective strategy must define what is protected, how frequently backups are taken, how long they are retained, where backup copies are stored, how they are secured, and how recovery is validated.

AWS provides multiple services and capabilities that can be combined to establish a structured backup and recovery framework for production environments.

This article outlines key considerations for designing a secure, reliable, and business-focused AWS backup strategy.

Introduction

Moving an application to an AWS production environment requires more than deploying compute, databases, and networking components. Production workloads should be protected against unauthorized access, accidental configuration changes, data exposure, network attacks, and operational security incidents.

AWS recommends applying security across multiple layers, including identity and access management, detection, infrastructure protection, data protection, incident response, and application security. The AWS Well-Architected Security Pillar also emphasizes least privilege, traceability, defense in depth, encryption, automation, and preparation for security events.

This AWS production security checklist provides a practical set of controls to review before and after moving a workload to production.

Note: Security requirements vary based on the application, data classification, compliance requirements, and AWS services being used.

Introduction

Running workloads on Kubernetes in production introduces a different set of risks than running them in development or staging. Missing resource limits, misconfigured probes, weak RBAC policies, and absent backup strategies can all lead to outages, security incidents, or unpredictable scaling behavior once real traffic hits the cluster.

A structured readiness review helps confirm that a cluster and its workloads meet baseline requirements for reliability, security, and observability before they carry production traffic.

This checklist covers practical areas that can be reviewed to bring a Kubernetes cluster and its workloads to production readiness.

Architecture Overview

The diagram below shows how the areas in this checklist map onto a typical production Kubernetes setup: traffic enters through an ingress/load balancer, the cluster splits into a control plane and worker nodes, and the nodes depend on supporting services for images, secrets, observability, and storage.

Managing SSL certificates manually in Kubernetes can be time-consuming and error-prone. Using cert-manager with Cloudflare DNS-01 Challenge, you can automatically issue and renew Let's Encrypt certificates for your applications.

This guide covers:

- Installing cert-manager

- Creating a Cloudflare API Token

- Configuring Kubernetes Secret

- Creating a ClusterIssuer

- Issuing SSL certificates automatically

- Using specific Cloudflare Zones

Prerequisites

Before starting, ensure you have:

- Kubernetes Cluster

- kubectl configured

- NGINX Ingress Controller installed

- Domain managed by Cloudflare

- cert-manager installed

Verify cert-manager:

kubectl get pods -n cert-manager

All pods should be in Running state.

Step 1: Create a Cloudflare API Token

Cloudflare recommends using API Tokens instead of the Global API Key because they provide granular permissions and improved security.

Metabase does not provide an official option to permanently delete user accounts. When a user is deactivated, Metabase marks the account as inactive and prevents the user from logging in, while preserving the user's questions, dashboards, models, and other content.

In some administrative or data-retention scenarios, you may need to permanently remove a deactivated user and their associated records from the Metabase application database.

Important: Take a complete backup of the Metabase application database before making any changes.

Prerequisites

Before proceeding, ensure that you have:

- Root or administrative access to the Metabase application database.

- Access to the Metabase application database.

- A valid database backup.

- The email address or user ID of the deactivated user.

- Basic knowledge of SQL.

- The Metabase service stopped before making direct database modifications.

Introduction

Managing cloud costs is an important part of running workloads on AWS, especially for startups and growing businesses. As infrastructure expands, unused resources, oversized instances, unnecessary storage, and unexpected data-transfer charges can gradually increase the monthly AWS bill.

A regular cost review helps identify unnecessary spending while ensuring that applications continue to meet their performance, availability, and security requirements.

This checklist covers practical areas that can be reviewed to optimize AWS infrastructure costs without compromising business requirements.

Prerequisites

Before starting an AWS cost optimization review, ensure that you have:

- Access to the AWS account or required billing permissions.

- Access to AWS Cost Explorer.
