Comment on What is Docker?

  PKI.

  Apt and most release signing has a root of trust shipped with the OS and the PGP keys are cross signed on keyservers (web of trust).

  DCT is just TOFU. They disable it because it gives a false sense of security. Docket is just not safe.

    So, if I understand correctly: rather than using prebuilt images from Docker Hub or untrusted sources, the recommended approach is to start from a minimal base image of a known OS (like Debian or Ubuntu), and explicitly install required packages via apt within the Dockerfile to ensure provenance and security. Does that make sense?

      No. Its install the package with apt. Avoid docker completely.

      If the docker image maintainer has a github, open a ticket asking them to publish a Debian package

        I see your point about trusting signed Debian packages, and I agree that’s ideal when possible. But Docker and APT serve very different purposes — one is for OS-level package management, the other for containerization and isolation. That’s actually where I got a bit confused by your answer — it felt like you were comparing tools with different goals (due to my limited knowledge). My intent isn’t just to install software, but to run it in a clean, reproducible, and isolated environment (maybe more than one in the same hosting machine). That’s why I’m considering building my own container from a minimal Debian base and installing everything via apt inside it, to preserve trust while still using containers responsibly! Does this makes sense for you? Thank you again for wasting your time to reply to my dumb messages
