Podman Container for Converting Disk Images

This Podman container, built from the debian:latest image, is designed to automatically convert VHD, VHDX, and OVA files to QCOW2 format using qemu-img. It runs the conversion script convert.sh every 10 seconds to process new files in the /data/input directory, converting them to QCOW2 format and saving the results to /data/output.

Prerequisites

• Podman installed
• Basic knowledge of container management

Build and Run the Container

1. Build the container:

   podman build -t image-converter .

2. Run the container:

   podman run -d -v /path/to/local/input:/data/input -v /path/to/local/output:/data/output -v  /path/to/local/complete:/data/complete image-converter

   Replace /path/to/local/input and /path/to/local/output and /path/to/local/complete with the paths to your local directories for input and output files.

Directory Structure

• /data/input: Directory where VHD, VHDX, and OVA files should be placed for conversion.
• /data/output: Directory where the converted QCOW2 files will be saved.

Configuration

The container uses a cron job to execute the convert.sh script every minute. The script monitors /data/input for new files and converts any supported files it finds, logging the process to /var/log/convert.log.

convert.sh Script Overview

The convert.sh script performs the following steps:

1. Scans the /data/input directory for supported file types (.vhd, .vhdx, .ova, .raw). #will plan to add more in the future#
2. Converts each file to the QCOW2 format using qemu-img.
3. Logs the conversion status to /var/log/convert.log.

Example Usage

1. Place a .vhd, .vhdx, or .ova file in /path/to/local/input.
2. Check the /path/to/local/output directory after a few seconds for the converted QCOW2 file.
3. Review the log file at /var/log/convert.log for details of each conversion process.

This container is configured to run the convert.sh script as the main process, ensuring continuous file conversion in a loop with a 10-second wait time between scans.
