Building Open-Source DevOps Toolchain

During Transformation Towards Agile & DevOps, DevOps needs a platform where we can define a workflow with different Integrations. Implementing DevOps Culture into your workflow requires using specialized tools. Below is an outline of each key category of tools that need to be in your DevOps Toolkit, and the leading technologies to consider as you build the DevOps toolkit that best supports your team and your organization.

Source Code Management Tools

Everything we build can be expressed through code. But when everything is the code you need to be sure that you can control and perform branching on it – otherwise things could get chaotic. So to avoid that chaos we use SCM Tools that includes -
  • GitHub

GitHub is a web-based Git or Version Control Repository
  • Gitlab

Gitlab provided Git Repository Management, Code Review, Issue Tracking, Activity Feeds and Wikis.

Continuous Integration Tools

Continuous Integration is a fundamental best practice of modern Software Development. Setting up an effective Continuous Integration environment, we can
  • Reduce Integration Issues
  • Improve Code Quality
  • Improve Communication and Collaboration between Team Members
  • Faster Releases
  • Fewer Bugs
  • Continuous Integration using Jenkins

Jenkins is used as Continuous Integration Platform to merge code from individual developers into a single project, multiple times per day and test continuously to avoid any downstream problems.

Overview of Jenkins Features

  • Integration with SCM Tools
  • Secret Management
  • SSH-Based Access Management
  • Scheduling and Chaining of Build Jobs
  • Source Code Change Based Triggers
  • Worker/Slave Nodes
  • Rest API Support
  • Notification Management

Other Continuous Integration tools for consideration

  • TeamCity.
  • Bamboo.
  • Buddy.
  • GitLab CI.
  • CircleCI.
  • TravisCI.

Best Build Tools in DevOps

While building our organization, we have invested much of our time in research as which DevOps Tools we need to include in our DevOps toolkit and which not to. These decisions are based on our years of experience in the IT industry. We've taken great care in selecting, benchmarking and continually improving our tools selection. By sharing our Tools, we hope to foster a discussion within the DevOps community so that we can further improve.
  • Apache Maven For DevOps

Apache Maven is a Software Project Management and Comprehension Tool. Based on the concept of a Project Object Model (POM), Apache Maven can manage a project's build, reporting, and documentation from a central piece of information.
  • Apache Ant

Apache Ant is a Java library and command-line tool whose mission is to drive processes described in build files as targets and extension points dependent upon each other.
  • Gradle Build Tool

Gradle is a build tool with a focus on build automation and support for multi-language development.
  • Grunt - Javascript Task Runner

Grunt is a JavaScript task runner, a tool used to automatically perform frequently used functions such as Minification, Compilation, Unit Testing, Linting, etc.
  • GNU Make

Make is a build automation tool that automatically builds executable.
  • Packer - Build Automated Machine Images

Packer is a free and open-source tool for creating golden images for multiple platforms from a single source configuration.

DevOps Tools For Continuous Testing

To achieve the desired business goals of DevOps, you need to have an accurate, real-time measure of the risks and quality assurance of the features in your Delivery Pipeline and this can only be achieved through extensive and precise testing. Following are the testing tools being used by us to automate and streamline our DevOps Processes
  • Unit Testing With JUnit

JUnit is a simple framework to write repeatable tests.
  • Mocha - JavaScript Test Framework

Mocha is a simple, flexible, fun JavaScript test framework for Node.js.

Artifacts Repository Management Tools

Now that your build pipeline consistently versions your Maven project, you need a place to store your objects which are being produced at the end of this pipeline. These artifacts need to be stored much the same way your source code is stored in your Source Code Management System. This ensures access to previously released versions of your product. An Artifact Repository is designed to store your war/jar/ear/etc., and distribute it to fellow developers via Maven, Ivy, or the like, share your artifact with you deployment tools, and ensure an immutable history of your released products.
  • Using a Standard Artifacts Management System such as Artifactory
  • Caching Third-Party Tools

List of Configuration Management Tools

Configuration management is the process of standardizing resource configurations and enforcing their state across IT infrastructure in an automated yet agile manner.
  • Ansible - Simple IT Automation

Ansible is an agentless configuration management system which relies on SSH protocol.
  • Chef & Puppet

Chef and Puppet are agent-based configuration management system.

Continuous Deployment Tools

Continuous Deployment is a software development practice in which every code change goes through the entire pipeline and is put into production, automatically, resulting in many production deployments every day.
  • Supervisor - Process Control System

The Supervisor is a client/server system that allows its users to monitor and control some processes on UNIX-like operating systems.
  • PM2 - Production Process Manager For Node.JS

PM2 is an advanced, production process manager for Node.js.
  • Forever - CLI Tool

Forever is a simple CLI tool for ensuring that a given script runs continuously.

DevOps Orchestration Tools

Software systems that facilitate the automated management, scaling, discovery, and deployment of container-based applications or workloads.
  • Kubernetes - Container Orchestration

Kubernetes is an orchestration system for Docker containers. It handles scheduling and manages workloads based on user-defined parameters.
  • Orchestration with Docker Swarm

Docker Swarm provides native clustering functionality for Docker containers, which lets you turn a group of Docker engines into a single, virtual Docker engine.
