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.
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.
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
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
It’s actually how people build their images, in which some include sensitive data (when they should definitely not).
It’s the same problem as exposed S3 buckets actually, nothing wrong with docker in itself.
Actually yes, I had a look at them since i wanted to write HelmCharts for the community. That’s also where the community can step up, it can only be better 😊
I actually started looking into creating own Docker images because of how bad Lemmy’s Docker instructions are. I’m not even close to anything usable, though …
I guess it depends, if it’s a secret in use for the image, an attacker might use it to attack a pulled instance if the user deploying it didn’t change the secret. Kind of like an unchanged initial password.
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.
The amount of the internet and cloud infrastructure that is built on public Docker images makes this… worrying.

How can you be sure it doesn’t affect popular images? The probability may be lower, but I don’t think you can rule it out.

You are a fool because no helmet can protect you from a projectile that crossed space, survived entrance in the atmosphere. All that just to hit you

Isn’t it about people pushing their keys to public? I feel like this doesn’t affect the pulling side

aws s3 sync s3://barrys-nudes/ .
Have you seen the instructions on how to build the Lemmy images? That’s some crazy shit …
Actually yes, I had a look at them since i wanted to write HelmCharts for the community. That’s also where the community can step up, it can only be better 😊

I understand! If you need help to do that (or someone to contribute), hit me up ! 😄

Natural selection. Docker apes must suffer.
