Getting Started with the Falco Project: A Beginner's Guide

In the ever-evolving landscape of DevOps and cloud-native applications, security remains a top priority. As organizations increasingly adopt containerized environments, the need for robust security tools becomes paramount. Enter Falco, an open-source project originally created by Sysdig, designed to monitor and detect anomalous activity in your applications and infrastructure. In this article, we’ll explore the basics of using the Falco project to enhance your security posture. What is Falco? Falco is a cloud-native runtime security tool that detects unexpected behavior in your applications.

Using Zot Registry: A Comprehensive Guide for DevOps Engineers

In the rapidly evolving world of DevOps, containerization has become a cornerstone of modern software development and deployment practices. As organizations increasingly adopt container technologies, the need for efficient and secure container registries has grown. Zot Registry, an open-source OCI-compliant container registry, offers a compelling solution for managing container images. In this article, we’ll explore the features, benefits, and setup of Zot Registry, and how it can be integrated into your DevOps workflow.

Setting Up a Self-Hosted Docker Image Registry

In the world of containerization, Docker has become a cornerstone technology, enabling developers to package applications and their dependencies into a standardized unit called a container. While Docker Hub serves as a popular public registry for storing and sharing Docker images, there are scenarios where a self-hosted Docker image registry becomes essential. This article will guide you through setting up your own Docker image registry, providing greater control, security, and privacy over your container images.

Writing Data from Prometheus to Thanos

In the world of cloud-native applications, monitoring and observability are crucial for maintaining the health and performance of your systems. Prometheus has become a go-to solution for monitoring due to its powerful querying capabilities and ease of use. However, as organizations scale, they often encounter challenges with Prometheus’s storage limitations. This is where Thanos comes into play, extending Prometheus’s capabilities by providing long-term storage, high availability, and global querying across multiple Prometheus instances.

Writing Data from Prometheus to Cortex

Prometheus has become a cornerstone in the world of monitoring and observability, offering a powerful and flexible platform for collecting and querying metrics. However, as organizations scale, they often encounter limitations with Prometheus’s local storage, such as retention constraints and high availability challenges. This is where Cortex comes into play. Cortex is an open-source, horizontally scalable, and highly available multi-tenant long-term storage for Prometheus. In this article, we’ll explore how to write data from Prometheus to Cortex, enabling you to leverage the strengths of both systems.

Deploying a RabbitMQ Cluster with Three Nodes on Kubernetes

Deploying a RabbitMQ cluster in a Kubernetes environment can significantly enhance the resilience and scalability of message-driven applications. In this article, we will walk you through the steps to deploy a RabbitMQ cluster composed of three nodes on Kubernetes using open-source tools. Prerequisites Before we begin, ensure you have the following prerequisites set up: A Kubernetes cluster (Minikube, GKE, EKS, AKS, etc.) kubectl command-line tool installed and configured to interact with your cluster.

Light Alternatives for Kubernetes as a Container Orchestrator

Kubernetes has established itself as the de facto standard for container orchestration, providing a robust platform for managing containerized applications in production. However, it can be overly complex and resource-intensive for certain use cases, particularly for small applications, development purposes, or lightweight workloads. In this article, we will explore some light alternatives to Kubernetes that can serve as effective container orchestrators. 1. Docker Compose Overview Docker Compose is a simple tool used for defining and running multi-container Docker applications.
