That all makes sense. But when those 100 binaries end up as 100 OCI images, and then to patch them you need to update those 100 OCI images to have the new version, it does seem like we've gone in a circle a bit.

I mean, there are some advantages, if they all share the same base layer, maybe they share those libs at least on disk via a shared layer. But practically, though you are maybe not back where you started, you are at a place that seems to share some similarities.

This is one of the biggest issues with containers IMO. This and the layering system, which I think is poorly designed both to configure and to actually do the tasks it's meant to(build and delivery caching).

The solutions to this problem in the space have basically been to provide scanners to crack open the containers and detect things with known vulnerabilities. But I have not seen (m)any solutions around these scanners to facilitate the lifecycle of landing fixes.

Even if you provided a tree of a-proved base containers for each deployment lang in your org, you can't just update the base and deploy the world, there's not even tooling to automate working over the "FROM hierarchy" of images where you could detect which need to use new bases.

Because of the difficulty in managing large container hierarchies, in some orgs the later drives a common methodology of making image tags mutable, i.e. `ruby:myorg-v2`, which makes the FROM more like a dynamic link reference that gets updated automatically on the next build. I view this workaround as a regression brought on by the _still_ incredibly poor and complex SDLC tooling around managing images.

It's like for a few years the whole computing world forgot about security updates and went on a container bender, when woke up one morning realizing what they've done, and then started adding various clunky solutions on top: mutable tags, various tooling to take apart container images and inspect the junk in there, notify and scan for issues etc.

You mean like proposing JSON as XML replacement, rebuilding from scratch all the XML tooling including validation, and when almost done with it, replacing JSON with YAML?

[rdtsc]

Exactly! YAML apparently is now terrible as well, but not sure what's next in the pipeline, toml perhaps?

I think it would be funny if we reverted back to s-expressions and started the cycle all over.

You are right. If you put 100 dynamically linked binaries into 100 OCI images, then you have the same security issues all over again. As best practice, I would recommend using a container vulnerability scanner that can identify containers requiring updates (list CVEs). I think all major cloud providers have such a service available, and there are some free and open-source tools available, such as Trivy and Clair. It is also beneficial to use official container images that have frequent patches available for their base images. If you use a base image like 3.9-slim instead of 3.9.19-slim, you can, for example, pin your Python version to 3.9, but you get patches. But this again only works if you do not have a "FROM scratch" image with just a single fully static binary.
