Top 10 Beginner DevOps Projects

Here is a list of the top 10 most popular DevOps Projects for Beginners:

 

Dockerising applications

Docker has revolutionised how applications are packaged, deployed, and run across different environments. Dockerising, or containerising, an application involves encapsulating it and its dependencies into a lightweight, portable container. This container provides a consistent and isolated environment, ensuring the application runs consistently regardless of the underlying infrastructure.  

Dockerising applications offer numerous benefits. It eliminates the issue of "it works on my machine" by creating a standardised environment that can be easily reproduced. Developers can package their applications along with all the required libraries, dependencies, and configuration files into a Docker image. This image can then be shared with the operations team or deployed onto any system running Docker, ensuring consistent execution.  

Docker also enables scalability and efficient resource utilisation. Multiple containers can run on a single host, allowing applications to be divided into smaller, independent units that can be easily managed and scaled horizontally.  

Furthermore, Docker promotes faster deployment and continuous integration. With Docker, the process of deploying applications becomes much simpler and faster, as the containers can be started or stopped quickly. This speed and agility are particularly beneficial in environments requiring frequent updates or rollbacks.

Continuous Integration with Jenkins

Continuous Integration (CI) is a Software Development practice that involves regularly merging code changes from multiple developers into a shared repository. Jenkins, a popular open-source automation server, plays a crucial role in implementing CI pipelines.  

Jenkins facilitates CI by automating various tasks, such as building, testing, and deploying applications, in response to code changes. Here's how it works:   

1)  Whenever developers commit changes to the version control repository, Jenkins is triggered to initiate a series of predefined actions.  

2) Jenkins pulls the latest code from the repository and builds the application, compiling source code and resolving dependencies.   

3) It then runs automated tests to verify the integrity of the codebase.   

4) If the tests pass, Jenkins can deploy the application to a testing environment or even to production.  

Additionally, Jenkins integrates with various tools and frameworks to enhance CI capabilities. It can interact with Version Control Systems like Git, perform code analysis using static analysis tools, and generate reports on test coverage and code quality.

Configuration management with Ansible

Ansible is a free configuration management tool that makes automating and managing configurations for applications and infrastructure easier.

Using SSH to build connections with target machines and carry out configuration activities, Ansible runs agentless. To define ideal setups and coordinate actions on distant hosts, it uses strategies that are YAML-based. 

Tasks for installing packages, controlling services, setting up files, and carrying out other system-related tasks can be defined. A formal method is offered by Ansible playbooks, which define the system's desired state.

Its idempotent nature ensures consistent configurations, regardless of the initial system state. It’s great for automating repetitive tasks and maintaining system configurations.

Infrastructure-as-Code with Terraform

Infrastructure-as-Code (IaC) is like treating infrastructure as if it were software code. It’s a way to manage and create servers, databases, and other resources using code.

Terraform, developed by HashiCorp, is a popular IaC tool. It lets you define your desired infrastructure using configuration files. These files describe what resources you want (like servers or databases) and how they should be connected.

Terraform enables you to create and manage resources across different cloud providers (like AWS, Azure, or Google Cloud). It’s like writing a recipe for your infrastructure!

Terraform files use a language called HashiCorp Configuration Language (HCL). They allow you to specify what you need and how it all fits together. Plus, Terraform supports reusable components called modules for better organisation.

By using Terraform, you can create infrastructure blueprints that can be version-controlled, shared, and reproduced in different environments. This reduces manual work and ensures consistent infrastructure setup.

Terraform’s “plan” feature lets you preview changes before applying them, avoiding mistakes or unwanted modifications.
