Using Docker Compose with Kubernetes

Docker Compose can be used to deploy applications on Kubernetes using the Compose on Kubernetes tool. This article explains how to use Docker Compose with Kubernetes.

Installing Compose on Kubernetes

First, install the Compose on Kubernetes tool:

kubectl apply -f https://github.com/docker/compose-on-kubernetes/releases/download/v0.4.23/installer.yaml

Create a Compose file named docker-compose.yml:

version: '3'
services:
  web:
    image: nginx
    ports:
      - "80:80"

Deploy the Compose file to Kubernetes:
