Introduction Helm is a well-known Kubernetes package manager and an open-source tool used to streamline the installation, upgrading, and management of Kubernetes applications. With Helm, users can create version-controlled application releases that are easy to reproduce and manage. The tool simplifies deployment by allowing developers to package their applications as charts that can be easily deployed on any Kubernetes cluster. Keeping track of changes made to releases is paramount in ensuring a smooth and efficient deployment process. That's where Helm logs come into play. Logging release changes with Helm helps you understand what has changed between releases, identify ... Read More

Introduction SSH, short for Secure Shell, is an encryption protocol that provides a secure connection between two computers over an insecure network, such as the internet. It allows users to remotely and securely access and control another computer or server. SSH works by encrypting all data sent between the two computers, including any usernames and passwords used to log in. In order to establish a secure SSH connection between two computers or servers, SSH keys are necessary. An SSH key is a pair of cryptographic keys - one public and one private. The private key is kept on ... Read More
Introduction In today's digital age, cybersecurity is a top priority for businesses and organizations. Data breaches and cyber attacks can result in significant financial losses and damage to reputation. Kubernetes is a popular container orchestration system used by many organizations to manage their containerized applications. However, with the increase in the number of containers, securing them has become a significant challenge. A self-signed certificate provides a simple and cost-effective way to establish secure communication between different components of Kubernetes, including the API server, etcd, and kubelets. Generating a Self-Signed Certificate for Kubernetes A Step-by-Step Guide to Generating a ... Read More
Introduction In today's digital age, website security has become an extremely important aspect for businesses to consider. Cybercrime is on the rise and attackers are constantly finding new ways to exploit vulnerabilities in online systems. One of the main ways to protect websites from cyber threats is by implementing SSL/TLS certificates, which help encrypt data transmitted between a user's browser and a web server. A Certificate Signing Request (CSR) is an essential component of obtaining an SSL/TLS certificate. It contains information about the domain name and organization requesting the certificate, as well as other details required for verification purposes. ... Read More
Introduction A Certificate Signing Request (CSR) is a document that contains information about the entity requesting an SSL/TLS certificate. The CSR includes the public key and relevant identifying information about the entity, such as its name and location. This information is used by a certificate authority (CA) to verify that the entity requesting the certificate is who they claim to be. The CSR is an essential part of the process of obtaining an SSL/TLS certificate because it allows for verification of your identity and ownership of your domain. Without a valid CSR, you cannot obtain an SSL/TLS certificate, which ... Read More
Introduction In today's world, where most of the communication and data transfer happens over networks and the internet, security has become a crucial issue. An unsecured network can allow malicious users to intercept, modify, or steal sensitive data. To ensure secure communication over a network, encryption plays an essential role. Secure Shell (SSH) is an encrypted protocol that allows you to access a remote system securely. It provides secure communication between two untrusted hosts over an insecure network. SSH keys are the authentication credentials used by SSH for secure communication between systems. They provide a more secure way ... Read More
Introduction In today's digital age, secure communication is a top priority for individuals and businesses alike. When sensitive data is transmitted over the internet, it is important that it remains confidential and protected from unauthorized access. This is where SSH keys come in. SSH keys are a type of authentication method used to establish a secure connection between two networked devices. They are cryptographic keys that enable secure data transmission through encryption. Unlike traditional username/password authentication methods, SSH keys are much more secure. Passwords can be guessed or hacked, but SSH key pairs are nearly impossible to break. ... Read More

In this article we are going to understand about the rsync command in Linux that deals with remote file synchronization.This article will provide practical examples on how to use rsync with the most commonly used options. Remote Synchronization or rsync is a powerful command line utility tool that takes care of synchronizing the files and directories between two machines remotely as well locally.While synchronizing the files one machine will act as the host and the next one as the destination. Linux system administrators are the most that make use of this command. You can use rsync command, to copy and ... Read More
