Converting Docker Images from Portainer to Podman on Podman Desktop: A Comprehensive Guide

Introduction

Portainer is a popular, lightweight management UI for Docker that simplifies container orchestration tasks. However, if you are transitioning to Podman, which offers native support for Linux containers and can be used as an alternative to Docker, it's essential to understand how to migrate your existing Docker images from Portainer to Podman on Podman Desktop.

Step 1: Exporting Docker Images from Portainer

Before moving any images, ensure that you have a backup of the images in Portainer. This step is crucial because once an image is exported and imported into Podman, it will be managed by Podman rather than Portainer.

Open Portainer: Log in to your Portainer instance.
Navigate to Images: Go to the Images section where you can see a list of all Docker images.
Select Image(s): Choose the image or images that you want to export.
Export Image(s): Click on the Export button next to the selected image(s). This will download the image as a .tar file.

Step 2: Importing Images into Podman

Now, let's import these Docker images into Podman using Podman Desktop.

Open Podman Desktop: Launch Podman Desktop on your system.
Import Image(s):

In the Podman Desktop interface, go to Images or Containers.
Click on the + button and select Import from file.
Navigate to the location where you saved the .tar files from Portainer and select them.

Alternatively, you can use the command line for a more streamlined process:

podman load -i /path/to/image.tar

Step 3: Verifying Image Import

After importing the images, it's important to verify that they have been successfully imported into Podman.

List Imported Images: Use the following command in your terminal: bash podman image ls
Inspect an Image (Optional): You can inspect a specific image using: bash podman image inspect <image-name>

Step 4: Running Containers from Imported Images

Once the images are imported, you can run containers based on them.

Run a Container: Use the podman run command to start a container from an imported image: bash podman run -d --name <container-name> <image-name>
Verify Running Containers: List running containers using: bash podman ps

Step 5: Managing Imported Images in Podman Desktop

Podman Desktop provides a user-friendly interface to manage your imported images and containers.

Manage Containers: You can stop, start, or remove containers directly from the Podman Desktop UI.
Manage Images: Use the Images tab to view details about each image, including its size and tags.

Conclusion

Converting Docker images from Portainer to Podman on Podman Desktop involves a straightforward process of exporting images from Portainer and importing them into Podman using either the GUI or command line tools. By following these steps, you can ensure a smooth transition while maintaining control over your containerized applications.

If you encounter any issues during this migration, refer to the official documentation for both Portainer and Podman Desktop for additional support and troubleshooting tips.
