In this guide, we are going to use Docker to configure Jenkins and Tomcat to achieve Continuous Integration/Continuous Deployment. We will install and set up Tomcat and Jenkins using Docker, and thereafter we are going to create a Jenkins Job to deploy your Java application over the Tomcat server....

IntroductionTeams that work with Machine Learning (ML) workloads in production know that added complexity can bring projects for a grinding halt. While deploying simple ML workloads might seem like an easy task, the process becomes a lot more involved when you begin to scale and distribute these loads and implement...

Podman is the command-line interface tool that lets you interact with Libpod, a library for running and managing OCI-based containers. It is important to note that Podman doesn't depend on a daemon, and it doesn't require root privileges. The first part of this tutorial focuses on similarities between Podman and...

Application builds when broken down into multiple smaller service components, are known as Microservices. When compared to the traditional Monolithic way, a Microservice Architecture treats each microservice as a standalone entity/module, essentially helping to ease the maintenance of its code and related infrastructure. Each microservice of an application can...

In a previous article, we discussed How to improve your CI/CD workflow using GitHub Actions. Today we are going a step further. We will work with some additional actions to test our application, before submitting the Docker image and sending a notification to a Slack channel. First of all,...

TL;DR This article explores modern honeypots that leverage containerization by walking through the design of a high-interaction honeypot that can use arbitrary Docker containers to lure malicious attacks. Photo by Clint Patterson / Unsplash Introduction While honeypots have been around for a very long time, this article will attempt to...

Modern project development often requires developers to understand not one or two core technologies, but a whole range of them. It can involve different programming languages, structures, and databases or cloud operating systems. However, one of the main challenges is scaling and configuring the interactions and dependencies of these components...

ADD and COPY copy files to a Docker image. ADD can also extract tar archives and it can download files from URLs and copy them into the Docker image. The best practice is to use COPY....

In an ideal world, Docker containers should be ephemeral without any reliance on external storage. In the microservice world, this is achievable when services are connecting to external databases, queues, and other services. Sometimes though, we need persistent storage, when we're running services such as Jenkins, Prometheus, or Postgres. Fortunately,...

In this guide, we are going to deploy a continuous integration process between Jenkins, GitLab, and SonarQube. The end goal will be to review the code quality through SonarQube for GitLab repository using Jenkins. Following is the process flow we need to manage: Push code to GitLab from the local...
