With containerization gaining popularity over time and revolutionizing the process of building, shipping, and maintaining applications, it became the need of the hour to effectively manage these containers. Many tools were introduced to manage the lifecycle of these containers in large-scale systems. These tools were called container orchestration tools.
An orchestration tool takes care of provisioning and deployment, allocation of resources, load balancing, service discovery, high availability, and other important aspects of any system. By using container orchestration tools like Docker Swarm, Kubernetes, etc. we can easily describe the configurations such as volume mounts, env variables, image source, CPU, Memory configuration, etc., and use them as blueprints for creating containers.
