I’m sure plenty of the offenders are legitimate, but it’s completely safe to check private key pairs into code, or to bake them in to images. It entirely depends on what the key pairs are used for. Very common to include key pairs for development/test environments, for example. If it’s a production secret, of course you don’t do this.
We build all our image layers in house from a base nginx or node image. We’re moving to [scratch[(hub.docker.com/_/scratch/) soon to even eliminate going to Docker hub at all.
For home stuff, I don’t super care. I’ll just update as necessary and if something happens and someone gets in, it’s just my stuff.
Of course. In my opinion, what Docker is used for on Hub is a different model than it was originally supposed to solve. It was designed as a solution for enterprise where the development team had no easy control over the production environment, so the solution was to bundle the platform with the software. However, your production team is usually trustworthy, so leaking secrets via the container isn’t an issue (or actually sometimes you wanted the image to include secrets).
The fact that Hub exists is a problem in itself in my opinion. Even things like the AUR - which comes with its own set of problems - is a better solution.
nix provides a solution to build clean Docker images. But then again it only works for packages that are either in nixpkgs already or you have written a derivation for, the latter being probably more effort than a quick and dirty dockerfile.
Well not the Hub itself is the problem, rather the fact it’s being used wrong. You’re not supposed to publish your private images publicly, if you do that’s your problem. The Hub (or Docker) are pretty much completely unrelated to this issue. People who do this are probably also going to leave S3 buckets unsecured, commit passwords to Git and so on and so forth.
This isn’t really surprising and isn’t actually a real security issue with Docker itself or any of the popular public images. Docker Hub is a public registry so people inexperienced with Docker accidentally include secrets in their images and upload it to Docker Hub, this is actually pretty well known and the Docker docs specifically warn people about this.
The most popular images on Docker Hub are official / library images, they are curated and monitored by Docker for best practices and security vulnerabilities. I’m not saying that means you should trust them completely, it’s always best practice to read the source of an image before you use it.
Sane way you cant be sure your soap isnt poision, sure the manufacturing line could have messed up but like… the shady burger joint down the street is a lot more likely to have slipped up. The probability of anything is not zero, but we ignore a hell of a lot of possibilities
There is a nonzero probability of getting hit by a meteor at any time. A woman in Alabama was hit by one while she was inside her home, you’re not even safe indoors!
You all might think I’m a fool for wearing a helmet every time I leave my definitely meteor-proof house, but I’m not taking any chances.
Wait so who is the atmosphere and who are the solar winds in this metaphor? I’m having trouble seeing the point through all the pedantry over allegorical choice
This doesn’t mean that YOUR secrets are exposed by using the image, btw - this means that whomever built that image would be accidentally exposing their secrets.
Unless you built the image and added your secrets to it and then uploaded it to a public Docker registry. But again, that’s not a flaw in Docker.
Is this even a legitimate problem? Lots of people, myself included, have a "local" configuration. All of the services and credentials mentioned in the config are running on my personal machine for testing only during active development. None of those credentials refer to any sort of "real" service that's on 24/7 and accessible via the internet. It's effectively dummy data to the rest of the world and I imagine there are a ton of false positives like what I just described.
