How Can I Verify the Legitimacy of a Docker Image?

Asked By CuriousCoder99 On

I've been trying to validate a Docker image but I'm not having much luck. The image I'm looking at is from the Docker Hub: drpsychick/airprint-bridge. There's a GitHub repository associated with it that appears to be credible, but I'm unsure if the repository and the image are identical. It never hurts to double-check these things, right? Any assistance with this would be greatly appreciated! By the way, I accidentally referred to it as a container earlier; I meant image!

You can check the GitHub repository since it shows that they’re using CircleCI to publish that image to Docker Hub. Here's a link to the setup: [CircleCI Config](https://github.com/SickHub/docker-cups-airprint/blob/master/.circleci/config.yml). That's a good sign!

Nice to know! Thank you!

I’m the maintainer of the image, and yes, the build process is automated as mentioned. What can I do to enhance trust from your perspective?

Hello! I didn’t expect to see you here! What a nice surprise! The project itself seems trustworthy. I just wanted to hear others' opinions since there’s not much online about it. That you took the time to respond really boosts my confidence in the project. Thanks for reaching out! PS: Please excuse any mistakes in this message. I don't speak German and used Google Translate.

To verify the image, you can run `docker history` on it to see all the commands that were used to create it and its history. For a deeper dive, use the tool called "dive" to inspect the layers. This way, you could also try to find the Dockerfile on GitHub and build it yourself if needed.

Luckily, one exists. I’ll be looking through it later. Thanks for the info!
