Introduction Git is a version control system that allows developers to keep track of changes made to a codebase over time. Git tags are labels assigned to specific points in the history of a repository. They serve as markers that identify important milestones such as releases, versions, or checkpoints in the development process. Git tags are different from branches in that they are not meant to be updated or changed once they have been created. They provide an easy way to reference specific commits without having to remember the exact hash value associated with each commit. Why Delete ... Read More

Introduction Kubernetes is a popular open-source container orchestration tool that automates the deployment, scaling, and management of containerized applications. One of the essential features of Kubernetes is its ability to partition cluster resources using namespaces. Namespaces provide a way to segment the cluster into virtual sub-clusters, making it easier to manage and organize applications. Explanation of Kubernetes Namespaces Namespaces in Kubernetes act as virtual clusters that allow multiple teams or users to share a physical cluster without interfering with each other's workloads. By default, Kubernetes creates a namespace called "default, " where all deployed resources go unless a specific ... Read More

Introduction Git is a version control system that helps developers to manage changes and collaborate on projects efficiently. Git branches provide a way to work on different parts of the same project concurrently without interfering with each other's code. Branches serve as separate instances of a project, with their commit histories and codebases. This means that multiple developers can work on the same file at the same time without affecting each other's work. It also allows for testing new features before integrating them into the main project, enabling developers to experiment with new ideas without affecting the stability of ... Read More

Introduction When it comes to website security, HTTPS is an essential component. HTTPS, or Hypertext Transfer Protocol Secure, is a protocol that encrypts data being transmitted between a website and its visitors. The encryption ensures that any sensitive information shared on the site, such as login credentials or payment details, cannot be intercepted by third-party users. Without HTTPS, websites are vulnerable to attacks like man-in-the-middle attacks and phishing scams. These types of attacks can lead to significant data breaches and result in a loss of user trust. In addition to providing security benefits, HTTPS also has SEO benefits ... Read More
