Containerization & Kubernetes

The goal of this project is to containerize existing applications and services and deploy them on Kubernetes clusters, and by doing so, improve the scalability, reliability, and performance of the applications and services by leveraging the power of Kubernetes container orchestration platform.

Challenge

The goal of the project is to migrate the existing way of deploying applications and services from platform-native setup applications installed on physical servers or virtual machines to containerized setup deployed on Kubernetes clusters in public and private clouds. The challenge is to design and implement a containerization strategy that is efficient, scalable, and reliable. The project involves identifying the applications and services that can be containerized, creating Docker images for them, and deploying them on Kubernetes clusters.

Solution

Containerization

The stage involves creating Docker images for the applications and services. It includes creating Dockerfiles for building the images and defining the dependencies in the image build hierarchy. The containerization process ensures that the applications and services are packaged in a way that is portable, lightweight, and isolated from the underlying infrastructure.

Automated Builds

Automated builds via GitHub Actions are set up to build Docker images automatically whenever there is a change in the source code or configuration files. The integral part of the automated build process is to run tests, linters, and other quality control checks to ensure that the images are built correctly and meet the quality and security standards.

Deployment to Kubernetes

The final stage involves deploying the Docker images to Kubernetes clusters. The deployment process includes creating Kubernetes manifests for defining the desired state of the applications and services. It relies on Helm package manager for Kubernetes to manage complexity, templating and the deployment lifecycle, such as installing, upgrading, and rolling back releases. The deployment process ensures that the applications and services are running in a scalable, reliable, and performant way.
