Kompose vs Kustomize: What are the differences?

Introduction

Kompose and Kustomize are both tools that help in Kubernetes deployment and management. While they share some similarities, there are key differences between the two.

Package Structure: Kompose converts Docker Compose files into Kubernetes manifests, while Kustomize allows customization of Kubernetes resources through overlays and patches.
Level of Abstraction: Kompose provides a high level of abstraction by converting all Docker Compose features into their Kubernetes equivalents without any manual intervention. On the other hand, Kustomize offers a more fine-grained control by allowing customization of individual resources and parameters.
Complexity: Kompose offers a simpler approach as it directly converts Docker Compose files to Kubernetes manifests, making it easier for beginners or teams transitioning from Docker Compose. In comparison, Kustomize requires understanding and writing of overlays and patches, making it more suitable for advanced users who require granular control over their deployment.
Support for Templates: Kompose supports templating through the use of environment variables and variable substitution, enabling dynamic configuration. Kustomize, however, does not have inbuilt support for templating, although it has the ability to modify resources based on overlays.
Version Compatibility: Kompose is tightly coupled with the Docker Compose version it is based on, making it possible to encounter compatibility issues when there are significant changes between Docker Compose versions. Kustomize, on the other hand, is Kubernetes version-agnostic and can be used with any version of Kubernetes.
Community Support and Documentation: Kompose has a smaller community and limited documentation compared to Kustomize, which has gained wider acceptance and has comprehensive documentation due to being an official Kubernetes project.

In Summary, Kompose simplifies the migration of Docker Compose files to Kubernetes, while Kustomize provides more flexibility by allowing fine-grained customization of Kubernetes resources and parameters.

Detailed Comparison

Kompose	Kustomize
Kubernetes + Compose. Kompose takes a Docker Compose file and translates it into Kubernetes resources.	It introduces a template-free way to customize application configuration that simplifies the use of off-the-shelf applications. Now, built into kubectl as apply -k.
-	Purely declarative approach to configuration customization; Natively built into kubectl; Manage an arbitrary number of distinctly customized Kubernetes configurations; Available as a standalone binary for extension and integration into other services; Every artifact that kustomize uses is plain YAML and can be validated and processed as such

What are some alternatives to Kompose, Kustomize?

Kubernetes

Kubernetes is an open source orchestration system for Docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions.

Rancher

Rancher is an open source container management platform that includes full distributions of Kubernetes, Apache Mesos and Docker Swarm, and makes it simple to operate container clusters on any cloud or infrastructure platform.

Docker Compose

With Compose, you define a multi-container application in a single file, then spin your application up in a single command which does everything that needs to be done to get it running.

Docker Swarm

Swarm serves the standard Docker API, so any tool which already communicates with a Docker daemon can use Swarm to transparently scale to multiple hosts: Dokku, Compose, Krane, Deis, DockerUI, Shipyard, Drone, Jenkins... and, of course, the Docker client itself.

Tutum

Tutum lets developers easily manage and run lightweight, portable, self-sufficient containers from any application. AWS-like control, Heroku-like ease. The same container that a developer builds and tests on a laptop can run at scale in Tutum.

Portainer

It is a universal container management tool. It works with Kubernetes, Docker, Docker Swarm and Azure ACI. It allows you to manage containers without needing to know platform-specific code.

Codefresh

Automate and parallelize testing. Codefresh allows teams to spin up on-demand compositions to run unit and integration tests as part of the continuous integration process. Jenkins integration allows more complex pipelines.

CAST.AI

It is an AI-driven cloud optimization platform for Kubernetes. Instantly cut your cloud bill, prevent downtime, and 10X the power of DevOps.

k3s

Certified Kubernetes distribution designed for production workloads in unattended, resource-constrained, remote locations or inside IoT appliances. Supports something as small as a Raspberry Pi or as large as an AWS a1.4xlarge 32GiB server.

Flocker

Flocker is a data volume manager and multi-host Docker cluster management tool. With it you can control your data using the same tools you use for your stateless applications. This means that you can run your databases, queues and key-value stores in Docker and move them around as easily as the rest of your app.
