Observing Drone Statistics using Prometheus & Grafana

Using metrics exported by Drone Server, statistics like builds run, build status, etc., can be monitored and visualized with Prometheus & Grafana.

BIND9 DNS Server Setup in Docker

Implement a complete domain name resolution system for your Docker Containers using BIND 9 with this blog.

Deploying a Docker Registry with GUI

Set up a Docker Registry with a GUI interface to enhance your self-hosted Docker Registry experience.

Services and Tasks in Docker Swarm

Services, tasks and rollbacks are essential concepts closely linked to Docker Swarm and Docker Stack. Get a detailed understanding of them with the help of this article!

Deploying Applications with Docker Swarm

Learn the steps for deploying a simple application on Docker Swarm along with its uses, advantages, and disadvantages.

Drone Server and Runner Setup on Linux

Learn to set up Drone CI/CD servers and Drone Runners on a VPS, and also learn about the different components that make up a CI/CD definition YAML file.

Live Reload in Running Docker Containers

Using Docker for use cases which involve constant updates is tricky, as the container needs to be rebuilt repeatedly. The concept of Hot Reload is useful in Docker to update files inside containers while they run. Learn to implement it in this article!

CI/CD on Kubernetes with Argo

ArgoCD is a Kubernetes native CD tool capable of managing deployments for applications on Kubernetes. It's a declarative, GitOps-based CD tool that automates the entire deployment process.

Automating Infrastructure Provision on AWS with Terraform

Terraform converts code into infrastructure, simply known as an IaC (Infrastructure as Code). It can be used to deploy and destroy infrastructure on different cloud platforms.

Creating the Kubernetes Control Plane

Get guidance on setting up the Kubernetes Control Plane, also known as the cluster brain, with the help of this blog.

Generating Kubernetes Configuration Files for Authentication

Learn to set up kubeconfig files for authenticating and performing operations in the Kubernetes cluster with the help of this blog.

ETCD Server Setup for a Kubernetes Cluster

In this blog, we will work on setting up an etcd database in our Kubernetes cluster. etcd stores the state of all the components available in our cluster.

AWS Automation with Python and Boto3

Python's Boto3 Library can be used to automate infrastructure provisioning in AWS. Using Boto3 infrastructure, automation can be performed efficiently saving developers time and required effort.

TLS Certificates Management for a Kubernetes Cluster

In this blog, we will work on provisioning the Certificate Authority and setup TLS certificates for the different Kubernetes components.

Installing the Components required for a Kubernetes Cluster

Learn to build a Kubernetes cluster from scratch on a Linux machine using the available tools.

Patching Resources in Kubernetes

In Kubernetes, the Patch sub-command can be used to change the attributes of a resource deployed in a cluster. We'll learn about the different types of patch strategies and implement them in this article.

Log Rotation in Docker

Logs are essential telemetry data used to debug applications. Logs provide us with a better look into the health of our application, so container logs must be properly managed.

Scheduling in Kubernetes

One of the core features of Kubernetes is Pod scheduling, where Pods with different priorities can be placed on Nodes depending on the available resources. This guarantees cluster and node uptime and prevents mission-critical Pods from eviction.

Optimising Container Images Using Multi-Stage Docker Builds

Multi-stage builds in docker help us to streamline application deployment by decreasing app size and subsequently decreasing deployment times, leading to faster user feedback cycles.

Access Control in Kubernetes

RBAC is an exceptional way in Kubernetes to limit access to required users depending upon user requirements. Being introduced recently in Kubernetes 1.20, it has been a game changer so far regarding cluster resource access and stopping privilege escalation in compromised clusters.
