Using Compose with Podman Desktop

Introduction

Podman Desktop is aimed at providing an amazing graphical experience of managing your containers. Developers who have worked on containers may also be fans of the Compose Spec.

Podman Compose is a community-driven tool that allows developers to run multiple containers at the same time and facilitate communication between them. Podman Compose requires a Compose YAML file with definitions about the containers that need to communicate.

If you are new to writing Compose files or Compose Spec, check out this guide for more information.

Get Started

In this tutorial, we will learn about working with containers on Podman Desktop generated using podman-compose. You can find more information about Podman Compose here.

1. Install Podman Compose

For macOS

There are many ways to install podman-compose on your macOS system. One of the easier ways is to use Homebrew. To install podman-compose, simply run the following command

brew install podman-compose

Refer the official installation guide to get the latest version of Podman Compose on your Windows or Linux system.

2. Using Podman Compose to run multiple containers

For this tutorial, we will use the flask-redis project from the awesome-compose repository. This repository consists of many sample projects for you to get started with Podman Compose.

  1. Open your Terminal window
  2. Change to the project directory
cd flask-redis
  1. Run the following command
podman-compose -f compose.yaml up -d

The compose.yaml file contains definitions for multiple containers within the flask-redis project.

3. Manage Compose with Podman Desktop

In order to check if the containers are running as expected, open Podman Desktop and click on the ‘Containers’ option on the left side of the application. You will notice that the containers are bundled together under a Pod named flask-redis (compose) in this case. Here, the compose within the bracket indicates that it is generated from a Compose YAML file.

You can further configure or work with these containers within the Podman Desktop application now that they are visible. Here, clicking on the ‘Open Browser’ button allows us to check if the application is running as expected.
