𝐹𝓇𝑒𝑒𝓆𝓊𝑒𝓃𝒸𝒾𝑒𝓈 – HTTP Headers and CSP

Project deployed at 𝒽𝓉𝓉𝓅𝓈://𝒻𝓇𝑒𝑒𝓆𝓊𝑒𝓃𝒸𝒾𝑒𝓈.𝓃𝑒𝓉𝓁𝒾𝒻𝓎.𝒶𝓅𝓅

This document outlines the active HTTP security headers and Content Security Policy (CSP) directives implemented for 𝐹𝓇𝑒𝑒𝓆𝓊𝑒𝓃𝒸𝒾𝑒𝓈. These mechanisms enforce strict transport security, framing protections, cross-origin isolation, dynamic script restrictions, and browser permissions lockdown, providing strong client-side hardening aligned with modern web security best practices.

Modern Helm Charts: Gateway API, TLS Certificates, and CI/CD Automation

Helm is the de-facto package manager for Kubernetes, enabling developers to define, install, and manage applications across Kubernetes clusters. This document outlines best practices and standards for custom Helm chart architecture, focusing on applications using the Gateway API and incorporating TLS certificates with cert-manager.

Note: This guide may not always reflect the most current versions of the Gateway API, cert-manager, or other dependencies. Always review the latest official documentation for updates.

1. Directory Structure

The Git command fsck, short for "file system check," is used to verify the integrity of a Git repository and identify any issues with the stored objects. It is particularly helpful for debugging, recovering lost objects, and analyzing the repository's state at a low level.

What `git fsck` Does

Checks Object Integrity: Ensures that all objects (blobs, trees, commits, etc.) in the repository are valid and match their SHA-1 hashes.
Identifies Unreachable Objects: Finds objects in the repository that are not reachable from any references (like branches, tags, or HEAD). These objects include:
- Dangling commits
- Dangling blobs
- Dangling trees
Detects Corruption: Reports if any objects are corrupted or missing.

What is a Dangling Blob?

In Git, a blob (binary large object) represents the content of a file. A dangling blob refers to a blob object that exists in the repository but is not referenced by any commit, tree, or other reachable objects. This typically occurs when a file is added to the staging area (index) but never committed, or when a commit that references the blob is removed or becomes unreachable.

Causes of Dangling Blobs

Staging Without Committing: Adding a file to the staging area using git add but not committing it can create a blob that isn't referenced by any commit. If the staged changes are later removed or overwritten without a commit, the blob remains in the repository without any references.
Amending Commits: When you amend a commit using git commit --amend, Git creates a new commit object and the previous commit becomes dangling if it's no longer referenced. The blobs associated with the original commit may also become dangling if not referenced elsewhere.

Git Stash Command Guide

Basic Commands

1. Save Changes to Stash

Temporarily save uncommitted changes.

git stash

General Kubernetes Commands

Check cluster information:
```
kubectl cluster-info
kubectl get nodes
```
List all resources in the current namespace:
```
kubectl get all
```

1. User Enters a Domain

The user types a URL (e.g., example.com) into the browser’s address bar.

2. DNS Resolves the Domain

The browser sends a request to a DNS server to translate the domain name into an IP address.
If the domain uses a Content Delivery Network (CDN), the DNS server may return the IP address of the nearest CDN server to optimize performance.

This guide explores HTML `<input>` element types with accessibility best practices. Each type includes WCAG enhancements like proper labeling and error handling, along with ARIA attributes to improve compatibility with assistive technologies. Following these practices helps create a more inclusive and accessible user experience for everyone.
