This means the server running Compose becomes a single point of failure. When working with a Docker Compose-based application, the server running the application must be kept running for the application to continue working.
In Kubernetes, multi-cluster or multi-cloud deployments are easier to configure and manage. This presents a network communication challenge when an application workload is distributed across multiple hosts or cloud providers. #Compose’s Single-Cluster LimitationĬontainers in Docker Compose are designed to run on a single host. Here are some factors that may make migration to Kubernetes the best choice for your applications. #Why Move from Docker Compose to Kubernetes?

This article will detail some of the reasons why you should transition from Docker Compose to Kubernetes and provide a step-by-step guide on how to carry out this migration using Kompose, as well as suggestions on other helpful tools for deploying. It is an open-source system for automating deployment, scaling, and management of containerized applications. Kubernetes is categorized as a container orchestrator or container scheduler. Compose makes it easy to define and start up a multi-container application and any accompanying services by using a single YAML file, then running a single command to start and run the entire application.
This problem of managing multiple containers is what prompted container orchestration tools like Docker Compose and Kubernetes.ĭocker Compose is an orchestration tool that simplifies the creation of Docker-based multi-container applications. This can be achieved manually with a few containers, but a large enterprise application would require an entire team dedicated to the task. These containers need to be deployed, managed, connected and updated. Companies with sizable workloads in production could end up running up to thousands of containers over time. However, containerization in an enterprise or production-grade environment presents different levels of complexity in terms of managing containerized applications at scale. In recent years, many companies have turned to containerization for application delivery.
