Flavio Poletti recently blogged about using Barcode::ZBar for reading QR codes. In a previous life I have written applications for workflows that involved reading QR codes from documents and have also used Barcode::ZBar very effectively…highly recommended.

Back then, iirc I had quite a struggle satisfying all of the dependencies required to get it actually work. I spent a little time after reading his article to see I could successfully build it once more, this time in a Docker container. The result is this project:

docker-barcode-zbar

It was a little difficult piecing together the required packages, but in the end it works!

Next, I may create a webservice from the container and install it on a Fargate cluster. The service will allow you to upload .png files and scan them for QR codes. Stay tuned!
